iphone - uitableview 触摸事件

Question

我在里面创建了一个按钮UITableViewCell，当我单击一个按钮时，我想用索引值转到作者视图控件。

 tapped  = [UIButton buttonWithType:UIButtonTypeCustom];

[tapped setFrame:CGRectMake(0, 0, 320, 100)];
[tapped setTitle:@"button" forState:UIControlStateNormal];

NSInteger tet;

tet = indexPath.row; 
[tapped addTarget:self action:@selector(tapped:) forControlEvents: UIControlEventTouchDown];

[Cell addSubview:tapped];

Answer 1

您应该使用 indexPath.row 标记按钮。

tapped.tag = indexPath.row;

在您的事件处理代码中，您应该使用该标签来查找索引。

-(void) tapped:(UIButton *)sender
{
    UIButton *btn = (UIButton *)sender;
    int index = btn.tag;
    //Do rest...
}

Answer 2

尝试这个

-(void) tapped:(UIButton *)sender
{
    UITableViewCell *clickedCell = (UITableViewCell *)[[sender superview] superview];
    NSIndexPath *indexPath = [myTableView indexPathForCell:clickedCell];
    int section = indexPath.section;
    // You get easily your index path row
    int row = indexPath.row;
    // push your controller 

}

首先更新你的代码

使用你的活动UIControlEventTouchUpInside

tapped  = [UIButton buttonWithType:UIButtonTypeCustom];

[tapped setFrame:CGRectMake(0, 0, 320, 100)];
[tapped setTitle:@"button" forState:UIControlStateNormal];

NSInteger tet;

tet = indexPath.row; 
[tapped addTarget:self action:@selector(tapped:) forControlEvents: UIControlEventTouchUpInside];

[Cell addSubview:tapped];

Answer 3

您可以按如下方式标记按钮：

tapped.tag = indexPath.row

而在 tapped 方法中，您可以按如下方式使用它：

-(IBAction)tapped:(id)sender
{
 UIButton *btn = (UIButton *)sender;
int index = btn.tag;

}

根据您的要求使用此索引...
