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

iOS 9 onwards :

As statusBarHidden method was Deprecated from iOS9 you need to add two values in plist as below :

<key>UIStatusBarHidden</key>
<true/>
<key>UIViewControllerBasedStatusBarAppearance</key>
<false/>

or by User Interface Please refre below image :

As statusBarHidden is Deprecated from iOS9 :

@property(readwrite, nonatomic,getter=isStatusBarHidden) BOOL statusBarHidden NS_DEPRECATED_IOS(2_0, 9_0, "Use -[UIViewController prefersStatusBarHidden]") __TVOS_PROHIBITED;

Answer 2

Add following line in viewdidload

  [[UIApplication sharedApplication] setStatusBarHidden:YES
                                        withAnimation:UIStatusBarAnimationFade];

and add new method

  - (BOOL)prefersStatusBarHidden {
          return YES;
  }

also change info.plist file View controller-based status bar appearance" = NO

its works for me

Add the following to your Info.plist:

<key>UIStatusBarHidden</key>
<true/>
<key>UIViewControllerBasedStatusBarAppearance</key>
<false/>

Answer 4

I did the following and it seems to work (even in iOS 8):

- (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated
{
    if ([self respondsToSelector:@selector(setNeedsStatusBarAppearanceUpdate)]) {

        [[UIApplication sharedApplication] setStatusBarHidden:YES];
    }
}

- (BOOL)prefersStatusBarHidden {
    return YES;
}

Answer 5

Try that;

[[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationNone];

Answer 6

To answer the Susitha's question: use setNeedsStatusBarAppearanceUpdate. This will make a call to prefersStatusBarHidden to refresh with your desired status bar state. Try this:

    @property (nonatomic, getter=isHideStatusBar) BOOL hideStatusBar; // Give this a default value early

    - (BOOL)prefersStatusBarHidden {
        return self.isHideStatusBar;
    }

    - (void)someMethod {
    // triggered by an event or user action
    [self setHideStatusBar:YES];
    [self setNeedsStatusBarAppearanceUpdate];
    }

If you want to see the status bar again, set your property hideStatusBar (or whatever you call it) to NO. Call preferStatusBarHidden indirectly by making another call to

[self setNeedsStatusBarAppearanceUpdate]
