ios - 如何在 UIScrollView 中使用系统弹出手势？

Question

我在UINavigationController中有一个UIScrollView，但我发现当我触摸scrollView时无法使用系统的弹出手势，我应该如何解决冲突？

Answer 1

已修复，自定义左侧导航项导致此问题，我添加代码

if ([self.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {
            self.navigationController.interactivePopGestureRecognizer.delegate = nil;
        }

但在某些情况下仍然不起作用，应该修改为

if ([self.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {
            self.navigationController.interactivePopGestureRecognizer.delegate = self;
        }
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer
{
    return YES;
}

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldBeRequiredToFailByGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer
{
    return [gestureRecognizer isKindOfClass:UIScreenEdgePanGestureRecognizer.class];
}
