在UIWebView中检测ontouchend或onClick事件

Question

如何在UIWebView中检测onclick或ontouchend事件？ 或者这甚至可能吗？

谢谢。

Answer 1

子类UIWebView和实现

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{   
    //Do your code here

    [super touchesBegan:touches withEvent:event];
}

修改

您可以拦截使用此UIWebViewDelegate方法按下的URL：

- (BOOL)webView:(UIWebView*)webView shouldStartLoadWithRequest:(NSURLRequest*)request navigationType:(UIWebViewNavigationType)navigationType 
{
    NSURL *url = request.URL;
    NSString *link = url.absoluteString;
    NSLog(@"Link pressed: %@", link);

    return YES;
}

Answer 2

尝试这种方式：

 -(void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
    {

        UITouch *touch  = [touches anyObject];

    CGPoint currentLocation = [touch locationInView:webView];

    if(CGRectContainsPoint([webView frame], currentLocation)){

//perfrom action
}
}
