我们要实现的效果如下。

1.修改ControlView.h，即添加变量dict，用于存储TabelView的数据源。

#import <UIKit/UIKit.h>

@interface IkrboyViewController5 : UIViewController{

    NSMutableDictionary *dict;

}

@end

2.在ControlView.m添加如下修改

- (void)viewDidLoad

{

    [super viewDidLoad];

    [self initTableViewData];

	// Do any additional setup after loading the view.

}

-(void)initTableViewData{

    NSBundle *bundle = [NSBundle mainBundle];

    NSString *plistPath = [bundle pathForResource:@"user_head" ofType:@"plist"];

    NSArray *dataArr = [[NSArray alloc] initWithContentsOfFile:plistPath];

    //将所有数据分为三组

    NSMutableArray *arr1 = [NSMutableArray array];

    NSMutableArray *arr2 = [NSMutableArray array];

    NSMutableArray *arr3 = [NSMutableArray array];

    dict = [NSMutableDictionary dictionary];

    [dict setObject:arr1 forKey:@"Group1"];

    [dict setObject:arr2 forKey:@"Group2"];

    [dict setObject:arr3 forKey:@"Group3"];

    //设置划分数据的依据，即根据index分三组，index为0-1的为第一组，2-4为第二组，5为第三组

    for(NSInteger index = 0; index < [dataArr count]; index++){

        NSDictionary *item = [dataArr objectAtIndex:index];

        if(index<2){

            [arr1 addObject:item];

        }

        else if(index>=2&&index<5){

            [arr2 addObject:item];

        }

        else if(index>=5){

            [arr3 addObject:item];

        }

    }

}

3.初始化TableView

//分为多少个分组

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView

{

	return [[dict allKeys] count];

}

//每个分组的数据单元个数

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section

{

    switch(section)

    {

        case 0:

        {

            return [[dict objectForKey:@"Group1"] count];

        }

        case 1:

        {

            return [[dict objectForKey:@"Group2"] count];

        }

        case 2:

        {

            return [[dict objectForKey:@"Group3"] count];

        }

    }

    return 0;

}

//分组的标题，不实现下面的方法，不显示分组标题

- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section

{

    //dict allKeys取出的key arr无顺序，需进行排序

    NSArray *arr = [[dict allKeys] sortedArrayUsingSelector:@selector(compare:)];

	return [arr objectAtIndex:section];

}

//列表右侧的索引提示，不实现下面的方法，不显示右侧索引

-(NSArray *) sectionIndexTitlesForTableView: (UITableView *) tableView

{

    //dict allKeys取出的key arr无顺序，需进行排序

    NSArray *arr = [[dict allKeys] sortedArrayUsingSelector:@selector(compare:)];

    return arr;

}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

{

    static NSString *CellIdentifier = @"myTableCell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

    NSUInteger row = [indexPath row];

    NSUInteger section = [indexPath section];

    NSArray *arr;

    switch (section) {

        case 0:

            arr = [dict objectForKey:@"Group1"];

            break;

        case 1:

            arr = [dict objectForKey:@"Group2"];

            break;

        case 2:

            arr = [dict objectForKey:@"Group3"];

            break;

        default:

            break;

    }

    NSDictionary *rowDict = [arr objectAtIndex:row];

    cell.textLabel.text =  [rowDict objectForKey:@"itemName"];

    NSLog(@"cell.label.text =  %@",[rowDict objectForKey:@"itemName"]);

    NSString *imagePath = [rowDict objectForKey:@"itemImagePath"];

    cell.imageView.image = [UIImage imageNamed:imagePath];

    NSLog(@"cell.image.image  =  %@",imagePath);

    cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;

    return cell;

}

//选中Cell响应事件

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

    [tableView deselectRowAtIndexPath:indexPath animated:YES];//选中后的反显颜色即刻消失

    NSUInteger row = [indexPath row];

    NSUInteger section = [indexPath section];

    NSArray *arr;

    switch (section) {

        case 0:

            arr = [dict objectForKey:@"Group1"];

            break;

        case 1:

            arr = [dict objectForKey:@"Group2"];

            break;

        case 2:

            arr = [dict objectForKey:@"Group3"];

            break;

        default:

            break;

    }

    NSDictionary *rowDict = [arr objectAtIndex:row];

    NSString *userName =  [rowDict objectForKey:@"itemName"];

    NSLog(@"userName=%@",userName);

}
