在 UINavigationController 中隐藏导航栏时不向后滑动

No Swipe Back when hiding Navigation Bar in UINavigationController(在 UINavigationController 中隐藏导航栏时不向后滑动)

问题描述

我喜欢将视图嵌入到 UINavigationController 中继承的滑动包.不幸的是，我似乎无法找到隐藏 NavigationBar 的方法，但仍然让触摸屏向后滑动 gesture.我可以编写自定义手势，但我不喜欢而是依赖 UINavigationController 向后滑动 gesture.

I love the swipe pack thats inherited from embedding your views in a UINavigationController. Unfortunately i cannot seem to find a way to hide the NavigationBar but still have the touch pan swipe back gesture. I can write custom gestures but I prefer not to and to rely on the UINavigationController back swipe gesture instead.

如果我在情节提要中取消选中它，则向后滑动不起作用

if I uncheck it in the storyboard, the back swipe doesn't work

或者，如果我以编程方式隐藏它，同样的场景.

alternatively if I programmatically hide it, the same scenario.

- (void)viewDidLoad
{
    [super viewDidLoad];
    [self.navigationController setNavigationBarHidden:YES animated:NO]; // and animated:YES
}

有没有办法隐藏顶部 NavigationBar 仍然可以滑动?

Is there no way to hide the top NavigationBar and still have the swipe?

推荐答案

一个可行的方法是将 interactivePopGestureRecognizer 的 UINavigationController 委托设置为 nil 像这样:

A hack that is working is to set the interactivePopGestureRecognizer's delegate of the UINavigationController to nil like this:

[self.navigationController.interactivePopGestureRecognizer setDelegate:nil];

但在某些情况下，它可能会产生奇怪的效果.

But in some situations it could create strange effects.
