ios学习记录-UITableView

在.h文件中加上

UIViewController<UITableViewDelegate,UITableViewDataSource>//一个是代理，一个是数据源，

在viewDidLoad中初始化

tabView=[[UITableView alloc] initWithFrame:self.view.bounds];
    tabView.dataSource=self;//数据处理
    tabView.delegate=self;//事件代理
    tabView.allowsSelection=YES;
    array=[[NSMutableArray alloc] initWithObjects:@"a",@"b", nil];
    [self.view addSubview:tabView];

//table的行数
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{

    
    return array.count;
}
- (void) tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath:(NSIndexPath *)indexPath{
    /* Do something when the accessory button is tapped */ NSLog(@"Accessory button is tapped for cell at index path = %@", indexPath);
    UITableViewCell *ownerCell = [tableView cellForRowAtIndexPath:indexPath];
    NSLog(@"Cell Title = %@", ownerCell.textLabel.text);
}


- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath {
    return YES;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
    UITableViewCell *ownerCell = [tableView cellForRowAtIndexPath:indexPath];
    NSLog(@"Cell Title = %@", ownerCell.textLabel.text);

}

-(void)setEditing:(BOOL)editing animated:(BOOL)animated{//设置是否显示一个可编辑视图的视图控制器。
    [super setEditing:editing animated:animated];
    [self.tabView setEditing:editing animated:animated];//切换接收者的进入和退出编辑模式。
}
//可滑动删除
-(UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath{
//    if( (0 == indexPath.section) ){
//        return UITableViewCellEditingStyleDelete;
//    }else{
//        return UITableViewCellEditingStyleNone;
//    }
     return UITableViewCellEditingStyleDelete;
}

{
    if(editingStyle == UITableViewCellEditingStyleDelete)
    {
        
        [self.array removeObjectAtIndex:indexPath.row];
        [tabView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationLeft];
    }
