From  https://stackoverflow.com/questions/45372550/preferredstatusbarstyle-is-not-working If you want to set status bar style, application level then set  UIViewControllerBasedStatusBarAppearance  to  NO  in your  .plist  file. And in your  appdelegate >  didFinishLaunchingWithOptions  add following ine. [ UIApplication sharedApplication ] setStatusBarStyle : UIStatusBarStyleLightContent animated : YES ]; if you wan to set status bar style, at view controller level then follow these steps: Set the  UIViewControllerBasedStatusBarAppearance  to  YES  in the  .plist  file, if you need to set status bar style at UIViewController level only. In the viewDidLoad add function -  setNeedsStatusBarAppearanceUpdate override preferredStatusBarStyle in your view controller. - - ( void ) viewDidLoad { [ super viewDidLoad ]; [ self setNeedsStatusBarAppearanceUpdate ]; } - ( UIStatusBarStyle ) preferredStatusBarStyle { return UIStatusBarStyleLightContent ; }
