处理 UIWebview 内部的触摸

Handling touches inside UIWebview(处理 UIWebview 内部的触摸)

问题描述

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

I have created a subclass of UIWebView , and have implemented the touchesBegan, touchesMoved and touchesEnded methods.

但是 webview 子类没有处理 touch 事件.

but the webview subclass is not handling the touch events.

UIWebView子类里面有没有办法处理触摸事件???

Is there any method to handle the touch events inside the UIWebView subclass ???

推荐答案

不需要子类化，只需添加一个 UITapGestureRecognizer :

No subclassing needed, just add a 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];

在头文件中添加<UIGestureRecognizerDelegate>协议，并添加这个方法:

Add the <UIGestureRecognizerDelegate> protocol in the header file, and add this method:

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