以前寫過，忘了，回憶一下

第一步，infoPlist里面加一個這個

第二步，navigationController，和tabBarController 加上幾行代碼

/// UINavigationController
override var childViewControllerForStatusBarStyle: UIViewController? {
    return self.topViewController
}
override var childViewControllerForStatusBarHidden: UIViewController? {
    return self.topViewController
}
/// UITabBarController
override var childViewControllerForStatusBarStyle: UIViewController? {
    return self.selectedViewController
}
override var childViewControllerForStatusBarHidden: UIViewController? {
    return self.selectedViewController
}

第三步， 該怎么設置就怎么設置吧, 沒啥好說的了。。。

      /// In Controller
override var preferredStatusBarStyle: UIStatusBarStyle {
    return .lightContent
}
override var prefersStatusBarHidden: Bool {
    return false
}
