Question

我添加了两个uiimageview，一个在另一个subview uiview（imageview1,imageview2）上。在第一个视图中，顶部uiimageview被隐藏（imageview2），而在第二个视图中，底部imageview被隐藏（imageview1）。

分配点击手势：

UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(oneTap:)];
UITapGestureRecognizer *singleTap1 = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(oneTap:)];

将uiimageview的用户互动设置为YES。

[singleTap setNumberOfTapsRequired:1];
[singleTap1 setNumberOfTapsRequired:1];

//向uiimageview添加手势

分别添加点击手势识别器和选择器。

[imageview1 addGestureRecognizer:singleTap];
[imageview2 addGestureRecognizer:singleTap1];

但我的水龙头无法辨认。

任何人都能告诉我错误在哪里吗？

Answer 1

在添加手势识别器之前尝试设置setUserInteractionEnabled:YES。

[imageview1 setUserInteractionEnabled:YES]
[imageview2 setUserInteractionEnabled:YES]

[imageview1 addGestureRecognizer:singleTap];
[imageview2 addGestureRecognizer:singleTap1];

在您发表评论后，我建议您在检测到点击事件之前将您的观点置于顶部。因为父imageView在上面并且捕获了这些点击。

[yourparentview bringSubviewToFront:imageview1];
[yourparentview bringSubviewToFront:imageview2];

Answer 2

UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(oneTap:)];
singleTap.numberOfTapsRequired = 1;
singleTap.numberOfTouchesRequired = 1;
singleTap.delegate = self;
[imageview1 addGestureRecogniser:singleTap];
[singleTap1 release];

imageview1.userInteractionEnabled = YES; //disabled by default

点击手势在uiimageview上无法识别
