状态栏样式 - Swift 3 - 随时更改

Question

我发现很难以编程方式更改状态栏样式.

我看到如何使用(在ViewController.swift中)的组合为每个ViewController静态设置它:

override var preferredStatusBarStyle: UIStatusBarStyle {
    return UIStatusBarStyle.default
}

和(在info.plist中):

View controller-based status bar appearance = YES

...

我想随时改变它!

1.更改info.plist行查看基于控制器的状态栏外观并将其设置为NO

2.Change在appDelegate.swift在didFinishLaunchingWithOptions

UIApplication.shared.statusBarStyle = .lightContent

Answer 2

经过大量的挖掘后找到了答案!

设置(在info.plist中):

View controller-based status bar appearance = NO

并删除(在ViewController.swift中):

override var preferredStatusBarStyle: UIStatusBarStyle {
    return UIStatusBarStyle.default
}

...

现在你可以使用(在ViewController.swift中):

UIApplication.shared.setStatusBarStyle(UIStatusBarStyle.lightContent, animated: true)

并且,要初始为每个ViewController设置样式,请使用viewDidAppear:

override func viewDidAppear(_ animated: Bool) {
    UIApplication.shared.setStatusBarStyle(UIStatusBarStyle.lightContent, animated: false)
}
