swift - Setting statusbarStyle (deprecated in iOS 9.0)

Question

Just downloaded the new xCode 10.0 and saw that the old statusBarStyle has been deprecated since iOS 9.0.

Warning: Setter for 'statusBarStyle' was deprecated in iOS 9.0: Use -[UIViewController preferredStatusBarStyle]

Deprecated code: UIApplication.shared.statusBarStyle = .default

I tried using self.preferredStatusBarStyle, but found out the property is only a getter. So anyone knows how to set the statusBarStyle?

Edit

I want to change the statusBarStyle inside a function, where a user can switch between different themes. For example:

func changeStatusBar(toDarkMode: Bool) {
    if toDarkMode {
        // Set to light statusBarStyle
    } else { 
        // Set to default
    }
}

Answer 1

Set your darkMode variable using the same code you have now, then use it in the computed variable that the system is expecting:

var darkMode = false
override var preferredStatusBarStyle : UIStatusBarStyle {
    return darkMode ? .default : .lightContent
}

Depending on the context you may need to force a refresh of the screen for it to take effect. You would do that with the following call:

setNeedsStatusBarAppearanceUpdate()
