问题描述
我通常会隐藏状态栏
override func prefersStatusBarHidden() -> Bool {
return true
}
但Xcode给我一个错误，说方法不会覆盖其超类中的任何内容。
but Xcode is giving me an error, saying "Method does not override anything from its superclass".
如果我删除覆盖，Xcode会给出不同的错误：使用Objective-C选择器'prefersStatusBarHidden'的方法'prefersStatusBarHidden（）'与来自超类'UIViewController'的'prefersStatusBarHidden'的getter冲突，使用相同的Objective-C选择器
If I delete the override, Xcode gives a different error: "Method 'prefersStatusBarHidden()' with Objective-C selector 'prefersStatusBarHidden' conflicts with getter for 'prefersStatusBarHidden' from superclass 'UIViewController' with the same Objective-C selector"
我还在Target的常规设置中选中了隐藏状态栏：
I also have "Hide Status Bar" checked in my Target's general settings:
但状态栏仍然显示。
我发现另一个Stack Overflow回答中的这个方法
I found this method in another Stack Overflow answer
UIApplication.shared.setStatusBarHidden(true, with: .none)
但是这也不会隐藏状态栏。
but that doesn't hide the status bar either.
在Xcode 8 Beta 1中，我使用了第一种和第二种方法，它可以隐藏状态栏（第一种方法没有返回错误）。我现在可以用Xcode 8 Beta 4隐藏状态栏吗？
In Xcode 8 Beta 1, I used the first and second methods, which worked to hide the status bar (the first method did not return an error). What can I do now to hide the status bar, with Xcode 8 Beta 4?
注意：状态栏显示在Simulator设备和物理设备上，所有设备都运行iOS 10 。
Note: The status bar shows up on Simulator devices and physical devices, all running iOS 10.
推荐答案
我们需要在Swift 3上覆盖属性本身（这是Xcode 8 Beta 4中的新功能）：
We need to override the property itself on Swift 3 (this is new in Xcode 8 Beta 4):
override var prefersStatusBarHidden: Bool {
return true
}
