Hide Status Bar In iOS 8 app

Question

I have tried

[[UIApplication sharedApplication] setStatusBarHidden:YES];  

This does nothing.

And I have looked in my Info.plist file for "View controller-based status bar appearance" but it's not there.

How can I hide the white status bar at the top of the screen (with the clock and battery charge) inside my app for Xcode 6? Thank you!

You need to override this method on each view controller unless you have that plist entry.

Objective-C

-(BOOL)prefersStatusBarHidden{     return YES; } 

Swift 2

override func prefersStatusBarHidden() -> Bool {     return true } 

Swift 3+

override var prefersStatusBarHidden: Bool {     return true } 

And don't forget to set (if you present a view controller by calling the presentViewController:animated:completion: method):

Objective-C

vcToBeShownWithoutStatusbar.modalPresentationCapturesStatusBarAppearance = YES; 

Swift

vcToBeShownWithoutStatusbar.modalPresentationCapturesStatusBarAppearance = true

If you change status bar from some container view controller (eg. UINavigationController or UIViewController with child view controllers) and you would like to change view controller responsible for status bar you should use childViewControllerForStatusBarHidden: property. Eg:

Set first view controller instance always responsible for status bar management

Objective-C

- (UIViewController *)childViewControllerForStatusBarHidden {     return childViewControllers.first; // or viewControllers.first } 

Swift 2

override var childViewControllerForStatusBarHidden() -> UIViewController? {     return childViewControllers.first // or viewControllers.first } 

Swift 3+

override var childViewControllerForStatusBarHidden: UIViewController? {     return childViewControllers.first // or viewControllers.first } 

Set container view controller responsible for status bar management

Objective-C

- (UIViewController *)childViewControllerForStatusBarHidden {     return nil; } 

Swift 2

override func childViewControllerForStatusBarHidden() -> UIViewController? {     return nil } 

Swift 3+

override var childViewControllerForStatusBarHidden: UIViewController? {     return nil }
