objective-c - Objective-C : UITable Method "didSelectRowAtIndexPath" does not work if label is added to cell

Question

在我的实现中，我必须向单元格添加自定义标签。但是，我意识到这样做，自定义标签覆盖的单元格区域不会对用户的“点击”使用react，因此不会触发方法“didSelectRowAtIndexPath”。

CustomOHAttributLabel *questionLabel = [[CustomOHAttributLabel alloc]initWithFrame:CGRectMake(10, (60-labelHeight)/2, 280, labelHeight)];        

[cell.contentView addSubview:questionLabel];

有没有办法让整个单元格区域响应用户的触摸，即使在向其添加自定义标签后也是如此？

Answer 1

制作一个自定义按钮并将其放在 lavel 和 onClick 上调用相同的代码，请参阅此

CustomOHAttributLabel *questionLabel = [[CustomOHAttributLabel alloc]initWithFrame:CGRectMake(10, (60-labelHeight)/2, 280, labelHeight)];

UIButton *btn=[UIButton buttonWithType:UIButtonTypeCustom];
    btn.frame=CGRectMake(10, (60-labelHeight)/2, 280, labelHeight);
    [btn addTarget:self action:@selector(doSomeThing) forControlEvents:UIControlEventTouchUpInside];

[cell.contentView addSubview:questionLabel];
[cell.contentView addSubview:btn];



-(void)doSomeThing
{
  //write code which you write in didSelectRowAtIndexPath method
}


- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
   [self doSomeThing];
}
