How can I hide the status bar in iOS 7.1?

Question

In iOS 7.0, I hid the status bar in my apps by adding

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

to the info.plist. I just updated my testing iPad to iOS 7.1, and the status bar is now back in all of my apps. How can I hide it in both 7.0 and 7.1?

Update: This is only happening in iPhone apps running on the iPad, I don't see this problem on the iPhone or in the simulator.

Answer 1

In the view controllers in which you want the status bar hidden, add the following method

- (BOOL)preferStatusBarHidden {
  return YES;
}

Then you can call

[self setNeedsStatusBarAppearanceUpdate];

which will fire the change to the status bar. This call can be done inside of an animation block which will animate the change.

Answer 2

Try adding the following

   - (void)viewWillAppear:(BOOL)animated{
        NSLog(@"View will appear");
        [[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationNone];

    }

    - (void)viewWillDisappear:(BOOL)animated{

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

Answer 3

I can reproduce the problem with a single-view iPhone-only app running in iPhone-compatibility mode in the simulator. But only when selecting an iPad non-retina on iOS 7.1.

My findings:

• The status bar will not be hidden, whatever you specified in the plist or in code.
• The problem doesn't occur on retina iPads
• The problem doesn't occur on iOS 7 or iOS 6

I tried these keys in the .plist:

<key>UIStatusBarHidden</key>
<true/>
<key>UIStatusBarHidden~ipad</key>
<true/>

and

<key>UIViewControllerBasedStatusBarAppearance</key>
<false/>
<key>UIViewControllerBasedStatusBarAppearance~ipad</key>
<false/>

I also tried the ViewController based-solution as mentioned by @Irfan to no avail.

There also seems no way to detect if the statusbar is shown as [UIApplication sharedApplication].statusBarFrame returns {0, 0, 0, 0}
