How to hide the status bar programmatically in iOS 7?

Question

In ios7, how can I hide the statusbar programmatically? I am using XCode 4.6.1 (ios6.1) and I want to implement this in XCode itself.

Answer 1

If you need to hide/show it on a given view controller dynamically you can do something like this.

(Although I recommend just using - (BOOL)prefersStatusBarHidden to return your preference if you don't need it to change.)

// view controller header 
@interface MyViewController : UIViewController  {
    BOOL shouldHideStatusBar;
}
@end


@implementation

- (BOOL)prefersStatusBarHidden {
    return shouldHideStatusBar; // backed by your instance variable
}

- (void)setPrefersStatusBarHidden:(BOOL)hidden {
    shouldHideStatusBar = hidden;

    // Don't call this on iOS 6 or it will crash since the 
    // `setNeedsStatusBarAppearanceUpdate` method doesn't exist
    [self performSelector:@selector(setNeedsStatusBarAppearanceUpdate)];

    // [self setNeedsStatusBarAppearanceUpdate]; // (if Xcode 5, use this)
}

@end

Try this

[[UIApplication sharedApplication] setStatusBarHidden:YES];

Answer 3

My experience is that you need both the code and the value in the info.plist file in iOS 9 / Xcode 7.3.

Add this to your viewDidLoad method.

[[UIApplication sharedApplication] setStatusBarHidden:YES];

Add this to your info.plist file as a boolean value and set it to NO:

View controller-based status bar appearance

Answer 4

If using iOS 9.0+ and Swift. If you want to have status bar hidden in some view controllers but not all - make sure to have View controller-based status bar appearance value in Info.plist set to YES else same parameters will be used across all view controllers.

And override prefersStatusBarHidden in subclass of UIViewController

override var prefersStatusBarHidden: Bool {
    get {
        return true
    }
}

Similar can be done to change preferredStatusBarStyle

override var preferredStatusBarStyle: UIStatusBarStyle {
    get {
        return .lightContent
    }
}

Answer 5

Swift 4.1

step1. Set View controller-based status bar appearance in your info.plist to YES

step2. Type some code in your UIViewController, status bar will hide when you present the UIViewController.

private var statusBarIsHidden = false

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)

    statusBarIsHidden = true
    setNeedsStatusBarAppearanceUpdate()
}
override var prefersStatusBarHidden: Bool {
    return statusBarStatus
}

In case of iOS >= 7.0 use following code :

Syntax:

// Present in UIViewController of UIKit Frameworks
- (BOOL)prefersStatusBarHidden NS_AVAILABLE_IOS(7_0); // Defaults to NO

Usage:

- (BOOL)prefersStatusBarHidden {
    return YES;
}

---

In iOS < 7.0 use following code :

Syntax:

// Present in UIApplication of UIKit Frameworks
- (void)setStatusBarHidden:(BOOL)hidden withAnimation:(UIStatusBarAnimation)animation NS_AVAILABLE_IOS(3_2);

Usage:

[[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:UIStatusBarAnimationNone];
