• 解决右滑返回与scroll滑动的冲突

let gestureArray: [AnyObject] = self.navigationController!.view.gestureRecognizers!
// 当是侧滑手势的时候设置scrollview需要此手势失效即可
for gesture in gestureArray {
 if gesture.isKindOfClass(UIScreenEdgePanGestureRecognizer.self)
 {
   self.scroll.panGestureRecognizer.requireGestureRecognizerToFail(gesture as! UIGestureRecognizer)
   break
 }
}
