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

in iOS7 you should implement in your viewController

- (BOOL)prefersStatusBarHidden {
    return YES;
}

Answer 2

you can hide status bar to set the key value "View controller-based status bar appearance" NO in plist. This is easiest way.

or You can hide in code by using property statusBarHidden of UIApplication class.

[[UIApplication sharedApplication] setStatusBarHidden:YES];

Swift 3.0

Hide status bar for any particular view controller

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

Hide Status bas across the application

UIApplication.shared.isStatusBarHidden = true

and set the key value "View controller-based status bar appearance" NO in info plist of project.

This doesn't work on iOS 7. The correct answer is by @user2826529 – Madalynmadam

Works for me. Ensure you set the property he mentions in the plist appropriately. – Norwegian

Far the best solution. Forget all the stuff above. Apple made it way too complicated. – Dancer

Override code works perfectly in iOS 13, Xcode 11.3, Swift 5. UIApplication.shared.isStatusBarHidden is deprecated. – Derinna

Answer 3

- (void)viewDidLoad
{
    [super viewDidLoad];
    if ([self respondsToSelector:@selector(setNeedsStatusBarAppearanceUpdate)])
    {
        [self prefersStatusBarHidden];
        [self performSelector:@selector(setNeedsStatusBarAppearanceUpdate)];
    }
    else
    {
        // iOS 6
        [[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationSlide];
    }
}

// Add this method
- (BOOL)prefersStatusBarHidden {
    return YES;
}

It did not work for me. I have used this same but the status bar always shown. Please help.. – Paederast

[[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationSlide]; This will work and there is a property in info.plist where you can hide the status bar. – Cogitable

After hiding the statusbar, how can it be shown again? Because I want to alter the statusbar visible status programmatically. – Giorgia

There is no need to perform the selector. – Dehydrogenase

@AndrasHatvani The question specified using Xcode 4, which means that he doesn't have the iOS 7 API. He uses performSelector to avoid "no method found" warning. – Plano

@Giorgia See my answer if you still need to do this. – Plano

Answer 4

To hide for a specific ViewController (and then turn back on) when View controller-based status bar appearance set to NO:

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

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

Answer 5

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

Answer 6

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];

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
}

Answer 9

If anyone wanted the most updated way to do it (Swift 2.1 and latest Xcode 7.2)

1. Set "View controller based status bar appearance to NO in your info.plist"

2. UIApplication.sharedApplication().statusBarHidden = true // put inside app delegate somewhere (applicationWill or DidFinishLaunchingWithOptions:

Answer 10

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 11

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 12

on swift 4:

    UIApplication.shared.isStatusBarHidden = ..true/false

Setter for 'isStatusBarHidden' was deprecated in iOS 9.0: Use -[UIViewController prefersStatusBarHidden] – Selfdenial
