iOS開發解決頁面滑動返回跟scrollView左右划沖突

-(BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer
{
    // 首先判斷otherGestureRecognizer是不是系統pop手勢
    if ([otherGestureRecognizer.view isKindOfClass:NSClassFromString(@"UILayoutContainerView")]) {
        // 再判斷系統手勢的state是began還是fail，同時判斷scrollView的位置是不是正好在最左邊
        if (otherGestureRecognizer.state == UIGestureRecognizerStateBegan && self.contentOffset.x == 0) {
            return YES;
        }
    }
    
    return NO;
