Can't Hide Status Bar—Swift 3,
提问by owlswipe
I usually hide the status bar with
我通常隐藏状态栏
override func prefersStatusBarHidden() -> Bool {
return true
}
but Xcode is giving me an error, saying "Method does not override anything from its superclass".
但是 Xcode 给了我一个错误，说“方法不会覆盖其超类中的任何内容”。
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"
如果我删除override，Xcode 会给出一个不同的错误：“方法 'prefersStatusBarHidden()' 与 Objective-C 选择器 'prefersStatusBarHidden' 与来自超类 'UIViewController' 的 getter 冲突，使用相同的 Objective-C 选择器”
I also have "Hide Status Bar" checked in my Target's general settings:
我还在目标的常规设置中选中了“隐藏状态栏”：
but the status bar still shows up.
但状态栏仍然显示。
I found this method in another Stack Overflow answer
我在另一个 Stack Overflow 答案中找到了这个方法
UIApplication.shared.setStatusBarHidden(true, with: .none)
but that doesn't hide the status bar either.
但这也不会隐藏状态栏。
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?
在 Xcode 8 Beta 1 中，我使用了第一种和第二种方法，它们可以隐藏状态栏（第一种方法没有返回错误）。我现在可以做些什么来隐藏状态栏，使用 Xcode 8 Beta 4？
Note: The status bar shows up on Simulator devices and physical devices, all running iOS 10.
注意：状态栏显示在模拟器设备和物理设备上，所有设备都运行 iOS 10。

We need to override the property itself on Swift 3 (this is new in Xcode 8 Beta 4):
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）：
override var prefersStatusBarHidden: Bool {
return true
}
updated Swift 5+
更新 Swift 5+
override var prefersStatusBarHidden: Bool { true }
