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;
}
