当我通过调用滚动时隐藏我的导航栏:self.navigationController?.setNavigationBarHidden(true, animated: true)
I am hiding my navigation bar when I scroll by calling: self.navigationController?.setNavigationBarHidden(true, animated: true)
唯一的问题是导航栏没有完全隐藏.
The only problem is that the navbar doesnt get hidden all the way.
更奇怪的是，如果我推到一个新的 VC 并返回，现在尝试滚动导航栏会一直隐藏，这正是我想要的.
Whats even stranger is if I push to a new VC and go back and now try to scroll the navigation bar gets hidden all the way which is what I want.
如果重要的话，我会在 VC2 上隐藏导航栏，然后在我退出到 VC 1 时显示它.
If it matters I am hiding the navigation bar on VC2 then showing it when I exit back to VC 1.
这是我第一次尝试隐藏导航栏时的样子，它不会一直向上/底层视图显示太多.
This is what it looks when I try to hide the navbar first time, it doesnt go up all the way/underlying view showing too much.
如果我推到下一个 VC 并返回并现在尝试隐藏导航栏，它可以工作
If I push the to next VC and go back and now try to hide the navigationbar it works
我的视图对顶部布局有 0 的约束，因此它拥抱顶部
The my view has a constraint of 0 to top layout so its hugging the top
那么在隐藏导航栏时，如何让我的视图始终像第二张图片一样?
So how can I make my view always be like in the second image when hiding my navigation bar?
试试这个代码...
注意:这是解决您的问题的简单方法.如果您想要更多自定义外观导航栏和状态栏外观.您应该阅读我之前的评论...

将导航控制器属性 hidesBarsOnSwipe 设置为 true
Set navigation controller property hidesBarsOnSwipe to true
override func viewDidAppear(animated: Bool) {
super.viewDidAppear(animated)
navigationController?.hidesBarsOnSwipe = true
}
