Get iPhone Status Bar Height

Question

I need to resize some elements in relation to the height of the iPhone's Status Bar. I know that the status bar is usually 20 points high but this isn't the case when it's in tethering mode. It gets doubled to 40. What is the proper way to determine it's height? I've tried

[[UIApplication sharedApplication] statusBarFrame]

but it gives me 20 x 480 in landscape which is correct but then it gives me 320 x 40 in portrait. Why isn't it giving me the opposite of that (40 x 320)?

@Andy when tethering is active the status bar height increases to 40px — Kyle Decot, Jul 02 '14 at 15:28

The statusBarFrame returns the frame in screen coordinates. I believe the correct way to get what this corresponds to in view coordinates is to do the following:

- (CGRect)statusBarFrameViewRect:(UIView*)view 
{
    CGRect statusBarFrame = [[UIApplication sharedApplication] statusBarFrame];

    CGRect statusBarWindowRect = [view.window convertRect:statusBarFrame fromWindow: nil];

    CGRect statusBarViewRect = [view convertRect:statusBarWindowRect fromView: nil];

    return statusBarViewRect;
}

Now in most cases the window uses the same coordinates as the screen, so [UIWindow convertRect:fromWindow:] doesn't change anything, but in the case that they might be different this method should do the right thing.

Calling this method in `-[UIViewController viewWillAppear:]` didn't work. Two issues: 1. The view's window is `nil` then. 2. Even when I preceded the call to `-[UIWindow convertRect:fromWindow:]` with `if (view.window)`, when I popped back to the view controller in landscape mode, the statusBarFrame had width & height switched and the call to `-[UIView convertRect:fromView:]` didn't switch them back correctly. – ma11hew28 May 20 '13 at 23:50
@MattDiPasquale Why not call it in `viewDidAppear:` instead? – ThomasW May 21 '13 at 00:50

Because, I'm adjusting `self.collectionView.contentInset` based on `[UIApplication sharedApplication].statusBarFrame`. If I adjust it after the view appears, then you can see it jump. So, I must adjust it before the view appears. – ma11hew28 May 23 '13 at 00:06

Did you do it like this:

CGRect rect;

rect = [[UIApplication sharedApplication] statusBarFrame];
NSLog(@"Statusbar frame: %1.0f, %1.0f, %1.0f, %1.0f", rect.origin.x, rect.origin.y, rect.size.width, rect.size.height);

Yes I am. I mentioned that in my initial question. – Kyle Decot Apr 01 '11 at 08:57

You can also use NSStringFromCGRect: `NSLog(@"Statusbar frame: %@", NSStringFromCGRect(rect));` – progrmr Jul 26 '11 at 14:18

EDIT The iOS 11 way to work out where to put the top of your view content is UIView's safeAreaLayoutGuide See UIView Documentation.

DEPRECATED ANSWER If you're targeting iOS 7+, The documentation for UIViewController advises that the viewController's topLayoutGuide property gives you the bottom of the status bar, or the bottom of the navigation bar, if it's also visible. That may be of use, and is certainly less hack than many of the previous solutions.

This method works for portrait & landscape orientation.

-(float) statusBarHeight
{
    CGSize statusBarSize = [[UIApplication sharedApplication] statusBarFrame].size;
    return MIN(statusBarSize.width, statusBarSize.height);
}

// example call
float statusBarHeight = [self statusBarHeight];

could you please provide more details on your solution, thanks! – Alex Netkachov Jun 28 '14 at 22:09
This can be used in your ViewController implementation. For example in the 'viewDidLoad' method. – David Douglas Jun 28 '14 at 22:29

You could test which is the lesser of the two values, that will be the real height.

Thanks! [I implemented this idea](http://stackoverflow.com/a/16598350/242933). It's great! – ma11hew28 May 23 '13 at 00:09

Swift 2:

let statusBarHeight = UIApplication.sharedApplication().statusBarFrame.height

Swift 3 or Swift 4:

let statusBarHeight = UIApplication.shared.statusBarFrame.height

Advice: Don't forget to inject the UIApplication.shared do not just use the singleton in your code.

Why wouldn't I want to use the singleton? – Kyle Decot Jan 19 '17 at 20:07

Here is the Swift version if anyone needs it:

var screenStatusBarHeight: CGFloat {
    return UIApplication.sharedApplication().statusBarFrame.height
}

This is included as a standard variable in:
