ios - 状态栏样式-Swift 3-随时更改

我发现很难以编程方式更改状态栏样式。

我看到了如何使用(在ViewController.swift中)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

...

我想随时更改它!

最佳答案

经过大量的挖掘找到了答案!

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
}

...

现在您可以使用(在ViewController.swift中):

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

并且，要最初为每个ViewController设置样式，请使用viewDidAppear:

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