在UIWebView中检测ontouchend或onClick事件

Question

如何检测UIWebView中的onclick或ontouchend事件？ 或者这甚至可能吗？

谢谢。

Answer 1

子类的UIWebView并实施

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

    [super touchesBegan:touches withEvent:event]; 
}

可以拦截利用该UIWebViewDelegate方法按下网址：

- (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

试试这个方法：

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

     UITouch *touch = [touches anyObject]; 

    CGPoint currentLocation = [touch locationInView:webView]; 

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

//perfrom action 
} 
}
