iphone - 处理 UIWebview 内的触摸

Question

我创建了 UIWebView 的子类，并实现了touchesBegan、touchesMoved 和 touchesEnded 方法。

但是 webview 子类不处理 touch 事件。

UIWebView 子类中是否有处理触摸事件的方法？？？

Answer 1

无需子类化，只需添加 UITapGestureRecognizer :

UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(didTapMethod)];
[tap setNumberOfTapsRequired:1]; // Set your own number here
[tap setDelegate:self]; // Add the <UIGestureRecognizerDelegate> protocol

[self.myWebView addGestureRecognizer:tap];

添加 <UIGestureRecognizerDelegate>在头文件中添加协议(protocol)，并添加此方法:

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