iOS 当使用FD_FullscreenPopViewController的时候遇到scrollView右滑手势没法使用的解决

   当咱们在ViewController中有scrollView的时候, 可能会遇到右滑没法响应返回手势, 有如下解决办法:

  自定义scrollView, 实现该scrollView的如下方法便可:

@implementation GOfflineContentScrollView

 

-(BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer

{

    // 首先判断otherGestureRecognizer是否是系统pop手势

    if ([otherGestureRecognizer.view isKindOfClass:NSClassFromString(@"UILayoutContainerView")]) {

        // 再判断系统手势的state是began仍是fail，同时判断scrollView的位置是否是正好在最左边

        if (otherGestureRecognizer.state == UIGestureRecognizerStateBegan && self.contentOffset.x == 0) {

            return YES;

        }

    }

    return NO;

}
