ios - Swift 3.0中如何用代码控制Status Bar样式

Question

我使用代码:

override var preferredStatusBarStyle: UIStatusBarStyle {
    return UIStatusBarStyle.lightContent
}

然后我添加

<key>UIViewControllerBasedStatusBarAppearance</key><false/>

在 Info.plist 中。

但是StatusBar还是黑色风格!为什么？

UINavigationController 覆盖 View Controller 的首选状态栏样式。您可以通过子类化 UINavigationController 将控制权交还给 View Controller :

class BaseNavigationController: UINavigationController {

var statusBarStyle: UIStatusBarStyle?

override var preferredStatusBarStyle: UIStatusBarStyle {
    return statusBarStyle ?? .default
}

然后您可以在 View Controller 中设置 statusBarStyle 属性:

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)

    if let navigationController = navigationController as? BaseNavigationController {
        navigationController.statusBarStyle = preferredStatusBarStyle
    }
}

override var preferredStatusBarStyle: UIStatusBarStyle {
    return .default // any style you want
}
