[mainScrollView.panGestureRecognizer requireGestureRecognizerToFail:self.navigationController.interactivePopGestureRecognizer];
//scrollview 與 右滑手勢沖突問題解決
UIScreenEdgePanGestureRecognizer *screenEdgePanGestureRecognizer = self.navigationController.screenEdgePanGestureRecognizer;
[mainScrollView.panGestureRecognizer requireGestureRecognizerToFail:screenEdgePanGestureRecognizer];
