How to implement touch events in uiwebview?

I have tried various solutions provided on this site and others to implement touch events on uiwebview. But still I am not abl开发者_运维百科e to do this. Actually, i have created a article reader application. Here, I have added a uiwebview on the normal uiview. Now, I want to trace some user touch events on that particular webview. When I do this on normal view, it works perfectly. But if I try it on webview. it stops working. The solutions I tried before are

1. implementing touch methods like touchbegan touchended touchmoved touch cancelled

2 implementing uigesturerecognizer 3 implementing window touch events like send event

Now If anyone can help me or tell me where I am doing wrong or a new solution(other than this), then I will be thankful.

Put a transparent UIVIew on top of your UIWebView to capture touches. You can then act on them or optionally pass them down to the UIWebView using the touchesBegan deletage method.

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    [self.myUIWebView touchesBegan:touches withEvent:event];
}

Check this previous post for details: iOS - forward all touches through a view

I subclassed UIWebView and just "leeched" onto its gesture recognizers in subviews 2 levels deep (you could go recursively but thats enough for iOS6-7). Then you can do whatever you want with the touch location and gesture recognizer's state.

for (UIView* view in self.subviews) {
    for (UIGestureRecognizer* recognizer in view.gestureRecognizers) {
        [recognizer addTarget:self action:@selector(touchEvent:)];
    }
    for (UIView* sview in view.subviews) {
        for (UIGestureRecognizer* recognizer in sview.gestureRecognizers) {
            [recognizer addTarget:self action:@selector(touchEvent:)];
        }
    }
}
