ios - setStatusBarHidden not working

Question

In my UIViewController, I have:

- (void)viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];
    [[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationNone];
    [self.view sizeToFit];
}

Yet the view looks like this:

I'm sure this code runs. I load the view from a xib. I haven't done anything else to the status bar like change its style. What could be wrong?

Even when I set `application.statusBarHidden = YES" in my app delegate, I see:

Answer 1

In your app's plist, if you have "View controller-based status bar appearance" set to YES, put this code in the view controller in which you hide the status bar:

- (BOOL)prefersStatusBarHidden {
    return YES;
}

Else if "View controller-based status bar appearance" is set to NO, call the following whenever you want to hide the status bar.

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