再次遇到UIImageView的触地事件问题

Question

如果我的故事板包含

   View      
     |_my UIIMageView 1 
     |
     |_my UIImageView 2

我可以按照此post

的解决方案来处理触地事件

但是，如果我的故事板改为

   Scroll View      
     |_my UIIMageView 1 
     |
     |_my UIImageView 2

现在我无法在其中一个UIImageView上检测到触碰事件...... 请帮我解决这个问题..

Answer 1

可能不是您正在寻找的答案，但您应该考虑使用UIButtons而不是UIImageViews。

每个UIButton都有一个UIImageView以及它的所有触摸事件。

Answer 2

我用过：

    UITapGestureRecognizer *touch;

    UIImageView *anImageView = [[UIImageView alloc] initWithFrame:CGRectMake(20, 20, 100, 100)];
    anImageView.image = [UIImage imageNamed:@"iad.png"];
    [anImageView setUserInteractionEnabled:TRUE];
    anImageView.tag = 1001 ;

    touch = [[[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(test)] autorelease];
    touch.numberOfTapsRequired = 1;
    [anImageView addGestureRecognizer:touch];
    [scrollView addSubview:anImageView];
    [anImageView release];

- (void) test:(UIGestureRecognizer *)sender
{

     UIImageView *imageView = (UIImageView *)sender.view;

     switch (imageView.tag)
     {
        case 1001: 
         // your code
        break;

        case 1002:
         // your code
         break;
      }
 }
