Swift UIApplication.setStatusBarStyle不起作用 [英] Swift UIApplication.setStatusBarStyle Doesn't work

问题描述

这是我在 UIViewController 的子类中的实现：

Here's my implementation in a subclass of UIViewController:

override func viewWillAppear(animated: Bool) {
    super.viewWillAppear(animated)
    UIApplication.sharedApplication().setStatusBarStyle(UIStatusBarStyle.LightContent, animated: false)
}

我尝试将其放入AppDelegate初始化代码中（使用传入的UIApplication实例），但状态栏仍为黑色..

I tried putting it in AppDelegate initialisation code (using the passed in UIApplication instance), however the status bar is still black..

这是iOS 8的错误还是我做错了？

Is this a bug with iOS 8 or am I doing it wrong?

注意：我可能违反某人的法律这里通过讨论ios 8 ..它是一个普遍的问题，当编译时对ios 7也不起作用。

Note: I may be breaking someone's law's here by discussing ios 8.. Its a general problem that, when compiled doesn't work for ios 7 either.

更新：仍然不起作用，即使有价值在Info.plist和中的代码 - didFinishLaunchingWithOptions

Update: Still doesn't work, even with value in Info.plist and code in - didFinishLaunchingWithOptions

推荐答案

你真的应该在您的视图控制器上实现 preferredStatusBarStyle ：

You really should implement preferredStatusBarStyle on your view controller(s):

override func preferredStatusBarStyle() -> UIStatusBarStyle {
    return .LightContent
}
