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

当我们在ViewController中有scrollView的时候, 可能会遇到右滑无法响应返回手势, 有以下解决办法:

自定义scrollView, 实现该scrollView的以下方法即可:

@implementation GOfflineContentScrollView

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

{

// 首先判断otherGestureRecognizer是不是系统pop手势

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

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

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

return YES;

}

}

return NO;

}
