ios - 带有Tap Gesture Recognizer的UILabel无法正常工作

Question

我使用UICollectionViewCell设计了一个XIB，在该自定义单元中，我有一个UILabel已启用其用户交互功能。

当我设计viewcontroller时，在我的cell中，这是我的代码。

UITapGestureRecognizer *buyNowTapped = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(buyNowClicked:)];
buyNowTapped.numberOfTapsRequired = 1.0;
cell.buy.tag = indexPath.row;
cell.buy.userInteractionEnabled = YES;
[cell.buy addGestureRecognizer:buyNowTapped];

-(void)buyNowClicked : (id)sender
{
  UIButton *button;
  UILabel *label;
  if([sender isKindOfClass:[UIButton class]])
  {
      button = (UIButton *)sender;
      [self buyService:button.tag];
  }
  else if ([sender isKindOfClass:[UILabel class]])
  {
    label = (UILabel *)sender;
    [self buyService:label.tag];
  }
}

但是添加的轻击手势不起作用。

Answer 1

使用标签属性创建定制单元并使用

-(void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath
{
    NSLog(@"%ld", (long)indexPath.row);
}

注意:在某处添加了TapGestureRecognizer，它防止选择单元格 didselectitematindexpath
