ios - 从应用程序调用时更改状态栏的颜色

Question

我正在设置导航栏和状态栏。

static func setParamsBars(){
    let bounds = UIScreen.main.bounds

    UIApplication.shared.statusBarView?.backgroundColor = .clear

    UINavigationBar.appearance().tintColor = UIColor.white
    UINavigationBar.appearance().titleTextAttributes = [NSForegroundColorAttributeName : UIColor.white, NSFontAttributeName: UIFont(name: "SFUIDisplay-Regular", size: 18)!]

    let imagebar : UIImage = UIImage(color: UIColor(red: 136.0/255.0, green: 136.0/255.0, blue: 136.0/255.0, alpha: 0.8), size: CGSize(width: bounds.size.width, height: 84))!
    UINavigationBar.appearance().setBackgroundImage(imagebar, for: .default)
    UINavigationBar.appearance().shadowImage = UIImage()
    UINavigationBar.appearance().isTranslucent = true
}

并在 didFinishLaunchingWithOptions中调用此函数

我的第一个屏幕

我打了电话

然后，当我返回到应用程序时，状态栏会更改颜色


然后，我添加了以下代码。保证:

func applicationDidBecomeActive(_ application: UIApplication) {
    AppEventsLogger.activate(application)

    print("applicationDidBecomeActive")
    //AppDelegate.setParamsBars()
    //UINavigationBar.appearance().clipsToBounds = false
    //UINavigationBar.appearance().isTranslucent = true

    UIApplication.shared.statusBarView?.backgroundColor = .clear

}

Answer 1

尝试如下扩展UIApplication:

(并且您可以使用每个ViewController进行更改)

override var preferredStatusBarStyle: UIStatusBarStyle {
return .lightContent
}
