How to programmatically get iOS status bar height

Question

I know that currently the status bar  with the time  battery  and network connection  at the top of the iPhone iPad is 20 pixels for non-retina screens and 40 pixels for retina screens  but to future proof my app I would like to be able to determine this without hard coding values  Is it possible to figure out the height of the status bar programmatically

User · Answer

While the status bar is usually 20pt tall, it can be twice that amount in some situations:

when you're in the middle of a phone call (that's a pretty common scenario);
when the voice recorder, or Skype, or a similar app, is using the microphone in the background;
when Personal Hotspot is activated;

Just try it, and you'll see for yourself. Hardcoding the height to 20pt will usually work, until it doesn't.

So I second H2CO3's answer:

statusBarHeight = [[UIApplication sharedApplication] statusBarFrame].size.height;

Go with Martin s suggestion to the question  Get iPhone Status Bar Height   CGFloat AACStatusBarHeight         CGSize statusBarSize     UIApplication sharedApplication  statusBarFrame  size      return MIN statusBarSize width  statusBarSize height       And in Swift  func statusBarHeight   - gt  CGFloat       let statusBarSize   UIApplication shared statusBarFrame size     return Swift min statusBarSize width  statusBarSize height      It seems like a hack  but it s actually pretty solid  Anyway  it s the only working solution   Old Answer  The following code  which would go in your custom subclass of UIViewController  almost worked to support landscape  But  I noticed a corner case  when rotating from right   unsupported upside-down   left  for which it didn t work  switched height  amp  width    BOOL isPortrait   self interfaceOrientation    UIInterfaceOrientationPortrait  CGSize statusBarSize    UIApplication sharedApplication  statusBarFrame size  CGFloat statusBarHeight    isPortrait   statusBarSize height   statusBarSize width

For iOS 13 you can use   UIApplication shared keyWindow  windowScene  statusBarManager  statusBarFrame height

User · Answer

UIApplication shared statusBarFrame height was deprecated in iOS 13   statusBarFrame  was deprecated in iOS 13 0  Use the statusBarManager property of the window scene instead   You can retrieve status bar height in iOS 13 like follows  let statusBarHeight   view window  windowScene  statusBarManager  statusBarFrame height  NB  It s optional so make sure you have correct fallback

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

UIApplication sharedApplication  statusBarFrame size height  But since all sizes are in points  not in pixels  status bar height always equals 20   Update  Seeing this answer being considered helpful  I should elaborate   Status bar height is  indeed  equals 20 0f points except following cases    status bar has been hidden with setStatusBarHidden withAnimation  method and its height equals 0 0f points  as  Anton here pointed out  during an incoming call outside of Phone application or during sound recording session status bar height equals 40 0f points    There s also a case of status bar affecting the height of your view  Normally  the view s height equals screen dimension for given orientation minus status bar height  However  if you animate status bar  show or hide it  after the view was shown  status bar will change its frame  but the view will not  you ll have to manually resize the view after status bar animation  or during animation since status bar height sets to final value at the start of animation    Update 2  There s also a case of user interface orientation  Status bar does not respect the orientation value  thus status bar height value for portrait mode is  UIApplication sharedApplication  statusBarFrame size height  yes  default orientation is always portrait  no matter what your app info plist says   for landscape -  UIApplication sharedApplication  statusBarFrame size width  To determine UI s current orientation when outside of UIViewController and self interfaceOrientation is not available  use  UIApplication sharedApplication  statusBarOrientation   Update for iOS7  Even though status bar visual style changed  it s still there  its frame still behaves the same  The only interesting find about status bar I got      I share  your UINavigationBar s tiled background will also be tiled to status bar  so you can achieve some interesting design effects or just color your status bar  This  too  won t affect status bar height in any way

Using following single line code you can get status bar height in any orientation and also if it is visible or not   define STATUS BAR HIGHT        UIApplicationsharedApplication  statusBarHidden   0              UIApplicationsharedApplication  statusBarFrame size height  gt  100                UIApplicationsharedApplication  statusBarFrame size width                UIApplicationsharedApplication  statusBarFrame size height           It just a simple but very useful macro just try this you don t need to write any extra code

I just found a way that allow you not directly access the status bar height  but calculate it   Navigation Bar height - topLayoutGuide length   status bar height  Swift   let statusBarHeight   self topLayoutGuide length-self navigationController  navigationBar frame height   self topLayoutGuide length is the top area that s covered by the translucent bar  and self navigationController  navigationBar frame height is the translucent bar excluding status bar  which is usually 44pt  So by using this method you can easily calculate the status bar height without worring about status bar height change due to phone calls

Swift 3 or Swift 4   UIApplication shared statusBarFrame height

User · Answer

Don t forget that the status bar s frame will be in the screen s coordinate space  If you launch in landscape mode  you may find that width and height are swapped  I strongly recommend that you use this version of the code instead if you support landscape orientations   CGRect statusBarFrame    self window convertRect  UIApplication sharedApplication  statusBarFrame toView view     You can then read statusBarFrame s height property directly   View  in this instance should be the view in which you wish to make use of the measurements  most likely the application window s root view controller   Incidentally  not only may the status bar be taller during phone calls  it can also be zero if the status bar has been deliberately hidden
