我們要實現的效果如下。

1.修改ControlView.h，即添加變量dict，用于存儲TabelView的數據源。

Cpp代碼  

1. #import <UIKit/UIKit.h>  
2.   
3. @interface IkrboyViewController5 : UIViewController{  
4.     NSMutableDictionary *dict;  
5. }  
6.   
7. @end  

#import <UIKit/UIKit.h>@interface IkrboyViewController5 : UIViewController{    NSMutableDictionary *dict;}@end

 2.在ControlView.m添加如下修改

Cpp代碼  

1. - (void)viewDidLoad  
2. {  
3.     [super viewDidLoad];  
4.     [self initTableViewData];  
5.     // Do any additional setup after loading the view.  
6. }  
7.   
8. -(void)initTableViewData{  
9.     NSBundle *bundle = [NSBundle mainBundle];  
10.     NSString *plistPath = [bundle pathForResource:@"user_head" ofType:@"plist"];  
11.     NSArray *dataArr = [[NSArray alloc] initWithContentsOfFile:plistPath];  
12.     //將所有數據分為三組  
13.     NSMutableArray *arr1 = [NSMutableArray array];  
14.     NSMutableArray *arr2 = [NSMutableArray array];  
15.     NSMutableArray *arr3 = [NSMutableArray array];  
16.       
17.     dict = [NSMutableDictionary dictionary];  
18.     [dict setObject:arr1 forKey:@"Group1"];  
19.     [dict setObject:arr2 forKey:@"Group2"];  
20.     [dict setObject:arr3 forKey:@"Group3"];  
21.       
22.     //設置劃分數據的依據，即根據index分三組，index為0-1的為第一組，2-4為第二組，5為第三組  
23.     for(NSInteger index = 0; index < [dataArr count]; index++){  
24.         NSDictionary *item = [dataArr objectAtIndex:index];  
25.         if(index<2){  
26.             [arr1 addObject:item];  
27.         }  
28.         else if(index>=2&&index<5){  
29.             [arr2 addObject:item];  
30.         }  
31.         else if(index>=5){  
32.             [arr3 addObject:item];  
33.         }  
34.     }  
35. }  

- (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];    //將所有數據分為三組    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"];        //設置劃分數據的依據，即根據index分三組，index為0-1的為第一組，2-4為第二組，5為第三組    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

Cpp代碼  

1. //分為多少個分組  
2. - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView  
3. {  
4.     return [[dict allKeys] count];  
5. }  
6. //每個分組的數據單元個數  
7. - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section  
8. {  
9.     switch(section)  
10.     {  
11.         case 0:  
12.         {  
13.             return [[dict objectForKey:@"Group1"] count];  
14.         }  
15.         case 1:  
16.         {  
17.             return [[dict objectForKey:@"Group2"] count];  
18.         }  
19.         case 2:  
20.         {  
21.             return [[dict objectForKey:@"Group3"] count];  
22.         }  
23.     }  
24.     return 0;  
25. }  
26. //分組的標題，不實現下面的方法，不顯示分組標題  
27. - (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section  
28. {  
29.     //dict allKeys取出的key arr無順序，需進行排序  
30.     NSArray *arr = [[dict allKeys] sortedArrayUsingSelector:@selector(compare:)];  
31.     return [arr objectAtIndex:section];  
32. }  
33. //列表右側的索引提示，不實現下面的方法，不顯示右側索引  
34. -(NSArray *) sectionIndexTitlesForTableView: (UITableView *) tableView  
35. {  
36.     //dict allKeys取出的key arr無順序，需進行排序  
37.     NSArray *arr = [[dict allKeys] sortedArrayUsingSelector:@selector(compare:)];  
38.     return arr;  
39. }  
40.   
41. - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath  
42. {

59.             break;

73.       
74.     return cell;  
75. }  
76.   
77. //選中Cell響應事件  
78. - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{  
79.     [tableView deselectRowAtIndexPath:indexPath animated:YES];//選中后的反顯顏色即刻消失  
80.     NSUInteger row = [indexPath row];  
81.     NSUInteger section = [indexPath section];  
82.     NSArray *arr;  
83.       
84.     switch (section) {  
85.         case 0:
