How to hide iOS status bar

Question

In my iOS video app status bar is hidden in some view controllers. I have done this using following code.

[[UIApplication sharedApplication] setStatusBarHidden:YES];

• It works for iOS 5 and iOS 6 , but not in iOS 7.

• I tried with this in particular view controller,

Eg:

-(BOOL)prefersStatusBarHidden { return YES; }

It works well, but I cant show status bar again in the parent view controller.

Answer 1

In the Plist add the following properties.

Status bar is initially hidden = YES

View controller-based status bar appearance = NO

now the status bar will hidden.

Answer 2

Here is the Swift version (pre iOS9):

override func viewWillAppear(animated: Bool) {
    super.viewWillAppear(animated)
    UIApplication.sharedApplication().setStatusBarHidden(true, withAnimation: UIStatusBarAnimation.None)
}

override func viewWillDisappear(animated: Bool) {
    super.viewWillDisappear(animated)
    UIApplication.sharedApplication().setStatusBarHidden(false, withAnimation: UIStatusBarAnimation.None)
}

This also works (iOS7+):

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

You also need to call:

setNeedsStatusBarAppearanceUpdate()

in say viewDidLoad().

Note that if you use a SplitView controller, or some other container view controller, you also need to have it return your class when its sent childViewControllerForStatusBarHidden. One way to do this is have a public weak var for say statusController, and return it in this overridden method.

FIXED SOLUTION FOR SWIFT 3+ (iOS 9, 10)

1- In info.plist set below property

2- Paste below code to Root controller , To

 private var isStatusBarHidden = true {
        didSet {
            setNeedsStatusBarAppearanceUpdate()
        }
    }

    override var prefersStatusBarHidden: Bool {
        return isStatusBarHidden
    }

You can call isStatusBarHidden = true and isStatusBarHidden = false where you want to hide/show status bar

Answer 4

• UIApplication.setStatusBarX are deprecated as of iOS9
• It's deprecated to have UIViewControllerBasedStatusBarAppearance=NO in your info.plist
• So we should be using preferredStatusBarX in all our view controllers

But it gets more interesting when there's a UINavigationController involved:

• If navigationBarHidden = true, the child UIViewController's preferredStatusBarX are called, since the child is displaying the content under the status bar.
• If navigationBarHidden = false, the UINavigationController's preferredStatusBarX are called, after all it is displaying the content under the status bar.
• The UINavigationController's default preferredStatusBarStyle uses the value from UINav.navigationBar.barStyle. .Default = black status bar content, .Black = white status bar content.
• So if you're setting barTintColor to some custom colour (which you likely are), you also need to set barStyle to .Black to get white status bar content. I'd set barStyle to black before setting barTintColor, in case barStyle overrides the barTintColor.
• An alternative is that you can subclass UINavigationController rather than mucking around with bar style.
• HOWEVER, if you subclass UINavigationController, you get no control over the status bar if navigationBarHidden = true. Somehow UIKit goes direct to the child UIViewController without asking the UINavigationController in this situation. I would have thought it should be the UINavigationController's responsibility to ask the child >shrugs<.
• And modally displayed UIViewController's only get a say in the status bar if modalPresentationStyle = .FullScreen.
• If you've got a custom presentation style modal view controller and you really want it to control the status bar, you can set modalPresentationCapturesStatusBarAppearance = true.

Answer 5

For better understanding add some photos with comments:

App before any changes

Found in your Project Navigator folder named Supporting Files and click on *.plist file

After you will get different setting of your app showed. You need to add 2 keys UIStatusBarHidden and UIViewControllerBasedStatusBarAppearance. You can do this simply clicking on + button

After pressing + you can choose one of the key - just start to type.

Correct version:

And finally application after applying this changes:

Answer 6

Try this simple method:

---

Objective-C:

- (void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated]
    [[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationNone];
}

- (void)viewWillDisappear:(BOOL)animated
{
    [super viewWillDisappear:animated]
    [[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:UIStatusBarAnimationNone];
}

---

Swift:

override func viewWillAppear(animated: Bool) 
{
    super.viewWillAppear(animated)
    UIApplication.sharedApplication().setStatusBarHidden(true, withAnimation: UIStatusBarAnimation.None)
}

override func viewWillDisappear(animated: Bool) 
{
    super.viewWillDisappear(animated)
    UIApplication.sharedApplication().setStatusBarHidden(false, withAnimation: UIStatusBarAnimation.None)
}
