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.

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
