第六篇、抽屉效果+UITabBarController(主流框架)

依赖于第三方的框架RESideMenu

1.AppDelegate.m中的实现

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch. //在AppDelegate.h中声明属性,初始化tabBarController
self.tabBar = [[UITabBarController alloc] init]; ViewController* vc1 = [[ViewController alloc] init];
vc1.tabBarItem = [[UITabBarItem alloc] initWithTabBarSystemItem:UITabBarSystemItemBookmarks tag:];
UINavigationController* nav1 = [[UINavigationController alloc] initWithRootViewController:vc1]; ViewController1* vc2 = [[ViewController1 alloc] init];
vc2.tabBarItem = [[UITabBarItem alloc] initWithTabBarSystemItem:UITabBarSystemItemContacts tag:];
UINavigationController* nav2 = [[UINavigationController alloc] initWithRootViewController:vc2]; self.tabBar.viewControllers = @[nav1,nav2]; //初始化leftVC
LeftController* left = [[LeftController alloc] init]; //初始化RESideMenu
RESideMenu* menu = [[RESideMenu alloc] initWithContentViewController:self.tabBar leftMenuViewController:left rightMenuViewController:nil];
self.window.rootViewController= menu;
return YES;
}

2.left左侧菜单

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
AppDelegate* GHDelegate = (AppDelegate* )[UIApplication sharedApplication].delegate;
ViewController1_1* vc = [[ViewController1_1 alloc] init]; //通过GHDelegate.tabBar.selectedIndex获得当前tabbaritem对应的nav,进行页面跳转
NSArray *arrControllers = GHDelegate.tabBar.viewControllers; if (GHDelegate.tabBar.selectedIndex==) {
UINavigationController* nav = (UINavigationController* )[arrControllers objectAtIndex:];
//隐藏sideMenuViewController
[self.sideMenuViewController hideMenuViewController];
//隐藏底部
vc.hidesBottomBarWhenPushed = YES;
[nav pushViewController:vc animated:YES];
}else{
UINavigationController* nav = (UINavigationController* )[arrControllers objectAtIndex:];
[self.sideMenuViewController hideMenuViewController];
vc.hidesBottomBarWhenPushed = YES;
[nav pushViewController:vc animated:YES];
} }

3.RESideMenu常见的属性设置

- (void)awakeFromNib
{
self.parallaxEnabled = NO; //视图差效果
self.scaleContentView = YES; //中心视图缩放功能打开
self.contentViewScaleValue = 0.95; //侧滑出现时缩放比
self.scaleMenuView = NO; //侧滑出来的视图是否支持缩放
self.contentViewShadowEnabled = YES; //中心视图阴影效果,打开显得有层次感。
self.contentViewShadowRadius = 4.5; //中心视图阴影效果Radius
self.panGestureEnabled = NO; //关闭拖动支持手势 //使用storyboard初始化中心视图和左视图。
self.contentViewController = [self.storyboard instantiateViewControllerWithIdentifier:@"contentViewController"]; //tabbar controller self.leftMenuViewController = [self.storyboard instantiateViewControllerWithIdentifier:@"leftMenuViewController"];
}

4.设置基本导航控制器

#import "LHLNavigationViewController.h"

@interface LHLNavigationViewController () <UIGestureRecognizerDelegate>

@end

@implementation LHLNavigationViewController

+ (void)load
{
UINavigationBar *navBar = [UINavigationBar appearanceWhenContainedIn:self, nil];
// 设置导航条字体
NSMutableDictionary *attr = [NSMutableDictionary dictionary];
attr[NSFontAttributeName] = [UIFont systemFontOfSize:];
[navBar setTitleTextAttributes:attr]; // 设置背景图片
[navBar setBackgroundImage:[UIImage imageNamed:@"navigationbarBackgroundWhite"] forBarMetrics:UIBarMetricsDefault];
} - (void)pushViewController:(UIViewController *)viewController animated:(BOOL)animated{ if (self.childViewControllers.count > ) { // 非根控制器
    // 自定义UIBarButtonItem的分类方法
UIBarButtonItem *item = [UIBarButtonItem backItemWitnImage:[UIImage imageNamed:@"navigationButtonReturn"] heighlightImage:[UIImage imageNamed:@"navigationButtonReturnClick"] target:self action:@selector(back) title:@"返回"];
viewController.hidesBottomBarWhenPushed = YES;
viewController.navigationItem.leftBarButtonItem = item;
} [super pushViewController:viewController animated:animated]; } - (void)back
{
[self popViewControllerAnimated:YES];
} - (void)viewDidLoad {
[super viewDidLoad];

  // 全屏返回手势
UIPanGestureRecognizer *pan = [[UIPanGestureRecognizer alloc] initWithTarget:self.interactivePopGestureRecognizer.delegate action:@selector(handleNavigationTransition:)];
pan.delegate = self;
self.interactivePopGestureRecognizer.enabled = NO;
[self.view addGestureRecognizer:pan]; }
/*
<UIScreenEdgePanGestureRecognizer: 0x7f7f98c97430;
state = Possible; delaysTouchesBegan = YES;
view = <UILayoutContainerView 0x7f7f98f19d00>;
target= <(action=handleNavigationTransition:,
target=<_UINavigationInteractiveTransition 0x7f7f98c96ee0>)>
*/ #pragma mark - UIGestureRecognizerDelegate
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch
{
return self.childViewControllers.count > ;
} - (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
} @end

5.设置UITabBarViewController

#import "LHLTabBarController.h"
#import "LHLEssenceViewController.h"
#import "LHLFriendTrendViewController.h"
#import "LHLMeViewController.h"
#import "LHLNewViewController.h"
#import "LHLPublishViewController.h"
#import "LHLTabBar.h"
#import "LHLNavigationViewController.h" @interface LHLTabBarController () @end @implementation LHLTabBarController // load方法只会调用一次
+ (void)load
{
// 设置某个类中的 UITabBarItem 按钮的颜色
UITabBarItem *item = [UITabBarItem appearanceWhenContainedIn:self, nil];
NSMutableDictionary *attrs = [NSMutableDictionary dictionary];
attrs[NSForegroundColorAttributeName] = [UIColor blackColor];
[item setTitleTextAttributes:attrs forState:UIControlStateSelected]; // 设置字体的尺寸:只有正常状态下设置才有效果
NSMutableDictionary *attrsNor = [NSMutableDictionary dictionary];
attrsNor[NSFontAttributeName] = [UIFont systemFontOfSize:];
[item setTitleTextAttributes:attrsNor forState:UIControlStateNormal];
} #pragma mark - 初始化
- (void)viewDidLoad {
[super viewDidLoad]; // 1.创建所有子控制器
[self setUpAllChildControllers]; // 2.2设置tabBar按钮的标题
[self setUpAllTitles]; // 3.使用自定义tabBar
[self setUpTabBar]; } #pragma mark - 自定义方法
- (void)setUpAllChildControllers
{
// 2.1.设置tabBar的子控制器
// 精华
LHLEssenceViewController *essenceVC = [[LHLEssenceViewController alloc] init];
LHLNavigationViewController *nav = [[LHLNavigationViewController alloc] initWithRootViewController:essenceVC];
[self addChildViewController:nav]; // 新帖
LHLNewViewController *newVC = [[LHLNewViewController alloc] init];
LHLNavigationViewController *nav1 = [[LHLNavigationViewController alloc] initWithRootViewController:newVC];
[self addChildViewController:nav1]; // 关注
LHLFriendTrendViewController *trendVC = [[LHLFriendTrendViewController alloc] init];
LHLNavigationViewController *nav3 = [[LHLNavigationViewController alloc] initWithRootViewController:trendVC];
[self addChildViewController:nav3]; // 我
LHLMeViewController *meVC = [[LHLMeViewController alloc] init];
LHLNavigationViewController *nav4 = [[LHLNavigationViewController alloc] initWithRootViewController:meVC];
[self addChildViewController:nav4]; } - (void)setUpAllTitles
{
// 精华
UINavigationController *nav = self.childViewControllers[];
[self setTitleButton:nav title:@"精华" image:@"tabBar_essence_icon" selectImage:@"tabBar_essence_click_icon"]; // 新帖
UINavigationController *nav1 = self.childViewControllers[];
[self setTitleButton:nav1 title:@"新帖" image:@"tabBar_new_icon" selectImage:@"tabBar_new_click_icon"]; // 关注
UINavigationController *nav3 = self.childViewControllers[];
[self setTitleButton:nav3 title:@"关注" image:@"tabBar_friendTrends_icon" selectImage:@"tabBar_friendTrends_click_icon"]; // 我
UINavigationController *nav4 = self.childViewControllers[];
[self setTitleButton:nav4 title:@"我" image:@"tabBar_me_icon" selectImage:@"tabBar_me_click_icon"];
} - (void)setTitleButton:(UINavigationController *)nav title:(NSString *)aTitle image:(NSString *)aImage selectImage:(NSString *)aSelectImage
{
nav.tabBarItem.title = aTitle;
nav.tabBarItem.image = [UIImage imageRenderOriginalWithName:aImage];
nav.tabBarItem.selectedImage = [UIImage imageRenderOriginalWithName:aSelectImage];
} - (void)setUpTabBar
{
LHLTabBar *tabBar = [[LHLTabBar alloc] init];
// 利用KVC对系统的tabBar进行赋值: KVC的原理是通过访问属性进行赋值,不是通过setter方法进行赋值
[self setValue:tabBar forKeyPath:@"tabBar"];
} @end

6.分类文件

#import "UIBarButtonItem+item.h"

@implementation UIBarButtonItem (item)
+ (UIBarButtonItem *)itemWitnImage:(UIImage *)aImage heighlightImage:(UIImage *)aSelectImage target:(id)aTarget action:(SEL)aAction

[plusButton setBackgroundImage:[UIImage imageNamed:@"tabBar_publish_icon"] forState:UIControlStateNormal];
[plusButton setBackgroundImage:[UIImage imageNamed:@"tabBar_publish_click_icon"] forState:UIControlStateHighlighted];
[plusButton sizeToFit];
[self addSubview:plusButton];
_plusButton = plusButton;

return _plusButton;
} - (void)layoutSubviews
{
[super layoutSubviews]; // 布局子控件
NSInteger count = self.items.count + ;
CGFloat btnW = self.lhl_width / count;
CGFloat btnH = self.lhl_height; NSInteger i = ;
for (UIButton *tabBarButton in self.subviews) {
