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。
Cpp代码
#import <UIKit/UIKit.h> @interface IkrboyViewController5 : UIViewController{ NSMutableDictionary *dict; } @end
#import <UIKit/UIKit.h>
@interface IkrboyViewController5 : UIViewController{
NSMutableDictionary *dict;
}
@end
2.在ControlView.m添加如下修改
Cpp代码
- (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]; } } }
- (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
Cpp代码
//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); }
//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);
}
