[IOS]非常不错的导航控制器的应用Demo

2022-03-28 11:34:15

我们在iPhone开发的过程中，估计UINavgationController是最最常用的控件之一吧，截下来我就用一个demo来举例导航控制器的应用。包含了tableview中增删查改的功能。

导航控制器的应用Demo

实现步骤：

1.创建一个Empty项目，命名为Navdemo。

2.创建一个根视图控制器，继承自UINavgationController，命名为FirstViewController。

FirstViewController.h：

#import <UIKit/UIKit.h>
@interface FirstViewController : UITableViewController
@property(nonatomic,retain) NSMutableArray *array;
@end

FirstViewController.m:

#import "FirstViewController.h"
#import "DXWDiscosureButtonViewController.h"
#import "DXWCheckViewController.h"
@interface FirstViewController ()

@end

@implementation FirstViewController
static NSString *CellIdentifier = @"Cell";
- (id)initWithStyle:(UITableViewStyle)style
{
    self = [super initWithStyle:style];
    if (self) {
        self.array = @[[[DXWDiscosureButtonViewController alloc] initWithStyle:UITableViewStylePlain],[[DXWCheckViewController alloc] initWithStyle:UITableViewStylePlain]];
        self.title = @"First";
    }
    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];
    //注册
    [self.tableView registerClass:[UITableViewCell class] forCellReuseIdentifier:@"Cell"];
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

#pragma mark - Table view data source

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
#warning Potentially incomplete method implementation.
    // Return the number of sections.
    return 1;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
#warning Incomplete method implementation.
    // Return the number of rows in the section.
    return [self.array count];
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    //[tableView registerClass:[SecondViewController class] forCellReuseIdentifier:@"aa"];
    
    //这个多一个最后的一个参数，必须要有上面一行注册过的才能这样用，不然的话就去掉最后一个参数
    //UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
    //UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
    //没有注册需要创建
//    if (cell == nil) {
//        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
//    }
    int row = [indexPath row];
    //当有多个view没有继承SecondVIewController的时候,可以这样写
    //[((UITableViewController *)self.array[row] valueForKey:@"Title")];
    
    cell.textLabel.text = ((DXWDiscosureButtonViewController *)self.array[row]).title;
    cell.imageView.image = ((DXWDiscosureButtonViewController *)self.array[row]).image;
    //有右边的>符号
    cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
    return cell;
}

#pragma mark - Table view delegate

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
//     DXWDiscosureButtonViewController *detailViewController = [[DXWDiscosureButtonViewController alloc] init];
    //[detailViewController release];
    int row = [indexPath row];
     [self.navigationController pushViewController:self.array[row] animated:YES];
}

@end

3.修改Delegate，设置根视图控制器

#import "DXWAppDelegate.h"
#import "FirstViewController.h"  //导入根视图控制器头文件
@implementation DXWAppDelegate

- (void)dealloc
{
    [_window release];
    [super dealloc];
}

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
    //创建首页
    FirstViewController *first = [[FirstViewController alloc] initWithStyle:UITableViewStylePlain];
    //创建一个导航栏，其中的首页是FirstViewController
    UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:first];
    //将导航栏作为根视图控制器
    self.window.rootViewController  = nav;
    
    self.window.backgroundColor = [UIColor whiteColor];
    [self.window makeKeyAndVisible];
    return YES;
}

4.创建所有子视图的一个基类控制器，命名为SecondViewController

SecondViewController.h:

#import <UIKit/UIKit.h>

@interface SecondViewController : UITableViewController
@property(nonatomic,retain)UIImage *image;
@end

SecondViewController.m:

#import "SecondViewController.h"

@interface SecondViewController ()

@end

@implementation SecondViewController
static NSString *cellRequestIdentifier = @"CellReuseIdentifier";
- (id)initWithStyle:(UITableViewStyle)style
{
    self = [super initWithStyle:style];
    if (self) {
        //self.title = @"SecondView";
    }
    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];
    //注册
    [self.tableView registerClass:[UITableViewCell class] forCellReuseIdentifier:cellRequestIdentifier];
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

#pragma mark - Table view data source

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
#warning Potentially incomplete method implementation.
    // Return the number of sections.
    return 1;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
#warning Incomplete method implementation.
    // Return the number of rows in the section.
    return 1;
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Cell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
    
    return cell;
}
#pragma mark - Table view delegate

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
  
}

@end

5.创建二级子视图控制器，也就是上图所示的水果选项卡的内容控制器，命名为DXWDiscosureButtonController,继承自SecondViewController。

DXWDiscosureButtonController.h:

#import "SecondViewController.h"

@interface DXWDiscosureButtonViewController : SecondViewController
@property(nonatomic,retain) NSMutableArray *array;
@end

DXWDiscosureButtonController.m:

#import "DXWDiscosureButtonViewController.h"
#import "ThirdViewController.h"
@interface DXWDiscosureButtonViewController ()

@end

@implementation DXWDiscosureButtonViewController

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        self.image = [UIImage imageNamed:@"disclosureButtonControllerIcon"];
        self.title = @"水果";
    }
    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];
    self.array = [[NSMutableArray alloc] initWithObjects:@"apple",@"orange",@"pitch",@"lenmon",@"balana", nil];
}

-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return [self.array count];
}

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Cell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
    }
    int row = [indexPath row];
    cell.textLabel.text = [self.array objectAtIndex:row];
//    cell.imageView.image = ((DXWDiscosureButtonViewController *)self.array[row]).image;
    //有右边的>符号
    cell.accessoryType = UITableViewCellAccessoryDetailDisclosureButton;
    return cell;
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

-(void)dealloc
{
    [self.array release];
    [super dealloc];
}


-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    int row = [indexPath row];
    UIAlertView *a = [[UIAlertView alloc] initWithTitle:@"Title" message:[NSString stringWithFormat:@"你选择了%@",self.array[row]] delegate:self cancelButtonTitle:@"OK" otherButtonTitles: nil];
    [a show];
    
}

//右边的>符号响应事件
-(void)tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath:(NSIndexPath *)indexPath
{
    int row = [indexPath row];
//    UIAlertView *a = [[UIAlertView alloc] initWithTitle:@"Title" message:[NSString stringWithFormat:@"你选择了%@",self.array[row]] delegate:self cancelButtonTitle:@"OK" otherButtonTitles: nil];
//    [a show];
    
    ThirdViewController *thirdViewController = [[ThirdViewController alloc] initWithNibName:@"ThirdViewController" bundle:nil];
    thirdViewController.str = self.array[row];
    [self.navigationController pushViewController:thirdViewController animated:YES];
    [thirdViewController release];
}

@end

6.创建第三级子视图控制器，也就是点击了某个水果选项卡的最右边的那个绿色按钮，会跳转到第三个视图，并且显示你所点击的水果名字，命名为ThirdViewController,继承自普通的ViewController,并且带有xib文件

[IOS]非常不错的导航控制器的应用Demo

ThirdViewController.h:

#import <UIKit/UIKit.h>

@interface ThirdViewController : UIViewController
@property (retain, nonatomic) IBOutlet UILabel *lblshow;
@property (nonatomic,copy) NSString *str;
@end

ThirdViewController.m:

#import "ThirdViewController.h"

@interface ThirdViewController ()

@end

@implementation ThirdViewController

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        self.title = @"ThirdViewController";
    }
    return self;
}


- (void)viewDidLoad
{
    [super viewDidLoad];
    self.lblshow.text = self.str;
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

- (void)dealloc {
    [_lblshow release];
    [super dealloc];
}
@end

7.创建根视图控制器的第二个选项卡的二级视图控制器，也就是选择的省市选项卡，命名为DXWCheckViewController，继承自tableViewController，不带xib文件

[IOS]非常不错的导航控制器的应用Demo

实现的效果是点击某行，这行显示mark

DXWCheckViewController.h:

#import "SecondViewController.h"

@interface DXWCheckViewController : SecondViewController
@property(nonatomic,retain) NSMutableArray *array;
@property(nonatomic,assign) int selectedValue;
@end

DXWCheckViewController.m:

#import "DXWCheckViewController.h"

@interface DXWCheckViewController ()

@end

@implementation DXWCheckViewController

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        self.image = [UIImage imageNamed:@"checkmarkControllerIcon.png"];
        self.title = @"省市";
    }
    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];
    self.selectedValue = -1;
    self.array = [[NSMutableArray alloc] initWithObjects:@"北京",@"上海",@"重庆",@"天津",@"江苏",@"浙江",@"河北",@"湖南",@"河南",@"湖北", nil];
}

-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return [self.array count];
}

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Cell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
    }
    int row = [indexPath row];
    cell.textLabel.text = [self.array objectAtIndex:row];
    //    cell.imageView.image = ((DXWDiscosureButtonViewController *)self.array[row]).image;
    //有右边的>符号
    //cell.accessoryType = UITableViewCellAccessoryDetailDisclosureButton;
    if (self.selectedValue == row) {
        cell.accessoryType = UITableViewCellAccessoryCheckmark;
    }
    else
    {
        cell.accessoryType = UITableViewCellAccessoryNone;
    }
    return cell;
}

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    int row = [indexPath row];
    //方法一：简洁明了的方法
    //self.selectedValue = row;
    //[tableView reloadData];
    //方法二：现货的以前的选中的cell,将其accessoryType设为None
    NSIndexPath *path = [NSIndexPath indexPathForRow:self.selectedValue inSection:0];
    //将轩中行的accessoryType设为Checkmark
    UITableViewCell *oldCell = [tableView cellForRowAtIndexPath:path];
    oldCell.accessoryType = UITableViewCellAccessoryNone;
    //将selectedValue设为当前轩中行
    self.selectedValue = row;
    UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
    cell.accessoryType = UITableViewCellAccessoryCheckmark;
}

-(void)dealloc
{
    [self.array release];
    [super dealloc];
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    
}

@end

8.添加继承自SecondViewController的班级选项卡的二级视图控制器，命名为ButtonViewController

ButtonViewController.h:

#import "SecondViewController.h"

@interface ButtonViewController : SecondViewController
@property(retain,nonatomic) NSArray *array;
@end

ButtonViewController.m:

#import "ButtonViewController.h"

@interface ButtonViewController ()

@end

@implementation ButtonViewController

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        self.image = [UIImage imageNamed:@"rowControlsIcon"];
        self.title = @"班级";
    }
    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];
	self.array = [NSArray arrayWithObjects:@"一班",@"二班",@"三班",@"四班",@"五班",@"六班",@"七班",@"八班",@"九班",@"十班",@"十一班",@"十二班",@"十三班",@"十四班",nil];
}
//行数
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return [self.array count];
}


-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *identifier = @"Identifier";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:identifier];
    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:identifier];
        UIImage *image = [UIImage imageNamed:@"button_up"];//设置button的背景图片
        UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
        [button setBackgroundImage:image forState:UIControlStateNormal];
        
        //button.frame = CGRectMake(0, 0, 150, 30);
        [button sizeToFit];//自适应图片的大小
        [button setTitle:@"详细信息" forState:UIControlStateNormal];
        [button addTarget:self action:@selector(buttonClick:) forControlEvents:UIControlEventTouchUpInside];
        cell.accessoryView = button;
    }
    cell.accessoryView.tag = [indexPath row];
    int row = [indexPath row];
    cell.textLabel.text = self.array[row];
    return cell;
}

-(void)buttonClick:(id)sender
{
    //通过button的上一级可以拿到那个cell，在通过cell来拿到它所在的行数，然后可以获得相应的数据
    UIButton *button = sender;
    UITableViewCell *cell = (UITableViewCell *)[button superview];
    NSIndexPath *indexpath = [self.tableView indexPathForCell:cell];
    int row = [indexpath row];
    NSLog(@"%d班",row+1);
    UIAlertView *a = [[UIAlertView alloc] initWithTitle:@"详细信息" message:[NSString stringWithFormat:@"%d班",row+1] delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
    [a show];
}

@end

9.创建可以移动的tableview效果，命名为MoveViewController，继承自SecondViewController，不带xib

操作：点击Edit按钮之后，可以点击每行右边的按钮进行拖动。

MoveViewController.h:

#import "SecondViewController.h"

@interface MoveViewController : SecondViewController
@property(retain,nonatomic)NSMutableArray *array;
@end

MoveViewController.m:

#import "MoveViewController.h"

@interface MoveViewController ()

@end

@implementation MoveViewController

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        self.title = @"Move";
        self.image = [UIImage imageNamed:@"moveMeIcon"];
        NSArray *arr = @[@"小明",@"小花",@"小李",@"小王",@"小丁",@"小张",@"小康",@"小刘",@"小墩",@"大墩"];
        self.array = [arr mutableCopy];
    }
    return self;
}

-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return [self.array count];
}

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *identifier = @"Identifier";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:identifier];
    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:identifier];
    }
    int row = [indexPath row];
    cell.textLabel.text = self.array[row];
    return cell;
}

- (void)viewDidLoad
{
    [super viewDidLoad];
    //首先要添加右上角的一个edit按钮，按钮按下去可以设置可以编辑
    UIBarButtonItem *button = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemEdit target:self action:@selector(itemButtonClick:)];
    //[button setTitle:@"move"];
	self.navigationItem.rightBarButtonItem = button;
}

-(void)itemButtonClick:(id)sender
{
    //设置可以编辑
    [self.tableView setEditing:!self.tableView.editing];//设置成和当前状态相反的状态
}
//设置编译图标
-(UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath
{
    return UITableViewCellEditingStyleNone;
}

//设置是否可以移动
-(BOOL)tableView:(UITableView *)tableView canMoveRowAtIndexPath:(NSIndexPath *)indexPath
{
    return YES;
}

-(void)tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath *)sourceIndexPath toIndexPath:(NSIndexPath *)destinationIndexPath
{
    id object= self.array[[sourceIndexPath row]];
    [self.array removeObject:self.array[[sourceIndexPath row]]];
    [self.array insertObject:object atIndex:[destinationIndexPath row]];
    NSLog(@"%d",[self.array count]);
}

@end

10.创建一个带删除功能的tableViewController,同样继承自SecondViewController，不带xib

[IOS]非常不错的导航控制器的应用Demo

DelViewController.h:

#import "SecondViewController.h"

@interface DelViewController : SecondViewController
@property(retain,nonatomic)NSMutableArray *array;
@end

DelViewController.m:

#import "DelViewController.h"

@interface DelViewController ()

@end

@implementation DelViewController

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        self.title = @"Delete";
        self.image = [UIImage imageNamed:@"deleteMeIcon"];
        NSArray *arr = @[@"小明",@"小花",@"小李",@"小王",@"小丁",@"小张",@"小康",@"小刘",@"小墩",@"大墩"];
        self.array = [arr mutableCopy];
    }
    return self;
}

-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return [self.array count];
}

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *identifier = @"Identifier";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:identifier];
    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:identifier];
    }
    int row = [indexPath row];
    cell.textLabel.text = self.array[row];
    return cell;
}


- (void)viewDidLoad
{
    [super viewDidLoad];
	//首先要添加右上角的一个edit按钮，按钮按下去可以设置可以编辑
    UIBarButtonItem *button = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemEdit target:self action:@selector(itemButtonClick:)];
    //[button setTitle:@"move"];
	self.navigationItem.rightBarButtonItem = button;
}


-(void)itemButtonClick:(id)sender
{
    //设置可以编辑
    [self.tableView setEditing:!self.tableView.editing];//设置成和当前状态相反的状态
    if (self.tableView.editing) {
        [self.navigationItem.rightBarButtonItem setTitle:@"Done"];
    }
    else
    {
        [self.navigationItem.rightBarButtonItem setTitle:@"Delete"];
    }
}
//设置编译图标
-(UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath
{
    return UITableViewCellEditingStyleDelete;
}

//将数据从数组和tableview中删掉
-(void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
{
    int row = [indexPath row];
    [self.array removeObjectAtIndex:row];
    [self.tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationRight];
}
//可以根据行来设置delete按钮位置上button的标题
-(NSString *)tableView:(UITableView *)tableView titleForDeleteConfirmationButtonForRowAtIndexPath:(NSIndexPath *)indexPath
{
    return @"我要删你";
}

@end

11.创建一个继承自SecondViewController，具有添加功能的视图控制器，命名为AddViewController

AddViewController.h:

#import "SecondViewController.h"

@interface AddViewController : SecondViewController<UIAlertViewDelegate>
@property(retain,nonatomic)NSMutableArray *array;
@property(retain,nonatomic)NSIndexPath *indexPath;
@end

AddViewController.m:

#import "AddViewController.h"

@interface AddViewController ()

@end

@implementation AddViewController

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        self.title = @"Add";
        self.image = [UIImage imageNamed:@"deleteMeIcon"];
        NSArray *arr = @[@"小明",@"小花",@"小李",@"小王",@"小丁",@"小张",@"小康",@"小刘",@"小墩",@"大墩"];
        self.array = [arr mutableCopy];
    }
    return self;
}

-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return [self.array count];
}

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *identifier = @"Identifier";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:identifier];
    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:identifier];
    }
    int row = [indexPath row];
    cell.textLabel.text = self.array[row];
    return cell;
}


- (void)viewDidLoad
{
    [super viewDidLoad];
	//首先要添加右上角的一个edit按钮，按钮按下去可以设置可以编辑
    UIBarButtonItem *button = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemEdit target:self action:@selector(itemButtonClick:)];
    //[button setTitle:@"move"];
	self.navigationItem.rightBarButtonItem = button;
}


-(void)itemButtonClick:(id)sender
{
    //设置可以编辑
    [self.tableView setEditing:!self.tableView.editing];//设置成和当前状态相反的状态
    if (self.tableView.editing) {
        [self.navigationItem.rightBarButtonItem setTitle:@"Done"];
    }
    else
    {
        [self.navigationItem.rightBarButtonItem setTitle:@"Delete"];
    }
}
//设置编译图标
-(UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath
{
    return UITableViewCellEditingStyleInsert;
}

//实现UIAlertView代理协议
-(void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex
{
    //获取AlertView中的数据
    NSString *str = [alertView textFieldAtIndex:0].text;
    //将数据插入到array数组中（位置是点击的位置的下一行）
    [self.array insertObject:str atIndex:[self.indexPath row]+1];
    //用点击位置的下一行创建一个新的NSIndexPath
    int newrow = [self.indexPath row]+1;
    NSIndexPath *index = [NSIndexPath indexPathForRow:newrow inSection:0];
    //在tableView的这个NSIndexPath中插入数据
    [self.tableView insertRowsAtIndexPaths:[NSArray arrayWithObject:index] withRowAnimation: UITableViewRowAnimationFade];
    
}

//添加
-(void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
{
    //获得点击的indexPath
    self.indexPath = indexPath;
    //创建一个UIAlertView,用来获得数据
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"enterstring" message:nil delegate:self cancelButtonTitle:@"ok" otherButtonTitles: nil];
    //带有输入框的UIAlertView
    alert.alertViewStyle = UIAlertViewStylePlainTextInput;
    [alert show];
    
    //添加固定的内容
//    [self.array insertObject:@"aaa" atIndex:[indexPath row]];
//    int row = [indexPath row];
//    [self.array removeObjectAtIndex:row];
//    [self.tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationRight];
}


@end

12.创建一个Person类,具有名字和年龄属性

Person.h:

#import <Foundation/Foundation.h>

@interface Person : NSObject<NSCopying>
@property(copy,nonatomic) NSString *name;
@property(assign,nonatomic) int age;
@end

Person.m:

#import "Person.h"

@implementation Person

-(id)copyWithZone:(NSZone *)zone
{
    Person  *p = [[Person alloc] init] ;  //拷贝函数不需要release,这里用autorelease会报错
    p.name = [self.name copy];
    p.age = self.age;
    return p;
}

-(NSString *)description
{
    NSLog(@"%@,%d",self.name,self.age);
}

@end

13.创建继承自SecondViewcontroller的具有修改功能的tableViewController,命名为ChangeViewController，不带xib文件：

ChangeViewController.h：

#import "SecondViewController.h"
#import "Person.h"

//申明协议,修改自己页面中的内容
@protocol change <NSObject>
//协议1
//-(void)changeData:(id)controller;//这里也可以是子视图的controller对象,然后想获取对象里面的任何值都可以
//协议2

导航控制器的应用Demo

实现步骤：

1.创建一个Empty项目，命名为Navdemo。

2.创建一个根视图控制器，继承自UINavgationController，命名为FirstViewController。

FirstViewController.h：

FirstViewController.m:

3.修改Delegate，设置根视图控制器

4.创建所有子视图的一个基类控制器，命名为SecondViewController

SecondViewController.h:

SecondViewController.m:

5.创建二级子视图控制器，也就是上图所示的水果选项卡的内容控制器，命名为DXWDiscosureButtonController,继承自SecondViewController。

DXWDiscosureButtonController.h:

DXWDiscosureButtonController.m:

6.创建第三级子视图控制器，也就是点击了某个水果选项卡的最右边的那个绿色按钮，会跳转到第三个视图，并且显示你所点击的水果名字，命名为ThirdViewController,继承自普通的ViewController,并且带有xib文件

ThirdViewController.h:

ThirdViewController.m:

7.创建根视图控制器的第二个选项卡的二级视图控制器，也就是选择的省市选项卡，命名为DXWCheckViewController，继承自tableViewController，不带xib文件

DXWCheckViewController.h:

DXWCheckViewController.m:

8.添加继承自SecondViewController的班级选项卡的二级视图控制器，命名为ButtonViewController

ButtonViewController.h:

ButtonViewController.m:

9.创建可以移动的tableview效果，命名为MoveViewController，继承自SecondViewController，不带xib

MoveViewController.h:

MoveViewController.m:

10.创建一个带删除功能的tableViewController,同样继承自SecondViewController，不带xib

DelViewController.h:

DelViewController.m:

11.创建一个继承自SecondViewController，具有添加功能的视图控制器，命名为AddViewController

AddViewController.h:

AddViewController.m:

12.创建一个Person类,具有名字和年龄属性

Person.h:

Person.m:

13.创建继承自SecondViewcontroller的具有修改功能的tableViewController,命名为ChangeViewController，不带xib文件：

ChangeViewController.h：

ChangeViewController.m：

14.创建可以保存修改值的三级子试图控制器，带有xib
