set custom color of status bar in swift?

问题

On a view controller, i want to set the color of status bar black but I am not able to change it. I am using below code for this purpose.

 func setUpUI() {
        self.navigationController?.setNavigationBarHidden(true, animated: false)
        UIApplication.shared.statusBarStyle = UIStatusBarStyle.default
    }

I have also added the value in info.plist

回答1:

You just override the return value of the status bar, like this:

override var preferredStatusBarStyle: UIStatusBarStyle {
   return .lightContent
}

回答2:

Use below code for swift 4 and Xcode 9.2.

1) In

info.plist Set

View controller-based status bar appearance Key to

NO

2) In

AppDelegate

didFinishLaunchingWithOptions

set Below Code

let statusBar: UIView = UIApplication.shared.value(forKey: "statusBar") as! UIView
    if statusBar.responds(to:#selector(setter: UIView.backgroundColor)) {
        statusBar.backgroundColor = UIColor.red
    }
    UIApplication.shared.statusBarStyle = .lightContent
