iPhone - 如何捕捉 UIWebView 或 UIImageView 的点击
我有一个像这样生成的视图：
oneView = [[UIView alloc] initWithFrame:CGRectMake(x, y , w, h)];
oneView.tag = i;
UITapGestureRecognizer* recognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleSingleTap2:)];
[recognizer setNumberOfTouchesRequired:1];
[oneView addGestureRecognizer:recognizer];
recognizer.delegate = self;
[recognizer release];
- (void)handleSingleTap2:(UITapGestureRecognizer *)recognizer {
int viewID = recognizer.view.tag;
NSLog(@"id : %d", viewID);
}
这有效，但是如果我用 UIWebView 或 UIImageView 分配替换 UIView 分配，则不再触发触摸事件。
我怎样才能让它发挥作用？
I have a View generated like this :
oneView = [[UIView alloc] initWithFrame:CGRectMake(x, y , w, h)];
oneView.tag = i;
UITapGestureRecognizer* recognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleSingleTap2:)];
[recognizer setNumberOfTouchesRequired:1];
[oneView addGestureRecognizer:recognizer];
recognizer.delegate = self;
[recognizer release];
- (void)handleSingleTap2:(UITapGestureRecognizer *)recognizer {
int viewID = recognizer.view.tag;
NSLog(@"id : %d", viewID);
}
This works, but if I replace the UIView alloc with a UIWebView or UIImageView alloc, then touch event is not triggerred anymore.
How may I make it work ?

设置 userInteractionEnabled=YES 并且如果需要 multipleTouchEnabled=YES
set userInteractionEnabled=YES and if needed multipleTouchEnabled=YES
关于您关于
UIWebView的问题，我建议您看看drawnonward的答案：UIGestureRecognizer 在 UIWebView 上工作吗？
对于 UIImageView 部分，请参阅此教程：
UIImageView-with-zooming-tapping
我无法将代码粘贴到此处，但我认为这将使该区域保持干净且更易于操作阅读。
Regarding your question about the
UIWebViewI suggest you have a look at drawnonward's Answer :Does UIGestureRecognizer work on a UIWebView?
And for the UIImageView Part see this Tutorial:
UIImageView-with-zooming-tapping
I could not paste the code here but i think this will keep this area cleaner and easier to read.
您必须重写
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer;委托函数并返回 YES;
you must override
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer;delegate function and return YES;
