Your question is similar to this one. A gesture recognizer on the UIWebView's embedded scroll view is capturing the gesture first. Add the following after you add the gesture recognizer to webView.

[webView.scrollView.panGestureRecognizer requireGestureRecognizerToFail:Swiperight];

Keep in mind that this will prevent users from panning to the left. If you don't want to do that then use UIScrollViewDelegate methods to detect when your user swipes or pans.
