Question

我在UIWebView添加了长按手势。但我希望UIWebView能够在识别出我的长按之前处理标准的Tap事件。（两个手势应该在Long Tap上处理 - 一个简单的Tap和我的Long Tap）。怎么做？

我认为需要在UIWebView上将Tap事件发送到TouchBegin。这是对的吗？

Answer 1

正确的代码：

- (void)viewDidLoad {
    UILongPressGestureRecognizer* gesture = [[[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(handleLongPress:)] autorelease];
    gesture.delegate = self;
    [myWebView addGestureRecognizer:gesture];
}

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer {
    return YES;
}

Answer 2

请参阅本节UIGestureRecognizerDelegate

http://developer.apple.com/library/ios/#documentation/uikit/reference/UIGestureRecognizerDelegate_Protocol/Reference/Reference.html

你发现当2个手势同时工作时会调用它。

gestureRecognizer:shouldRecognizeSimultaneouslyWithGestureRecognizer:

如何在UIWebView上的长按手势上创建Tap事件？
