Resize for in-call status bar?

Question

How can I make my view resize in response to the in-call status bar from my nib?

I figured it would just be setting the resize properties, but they're not enabled for the root UIView.

(I think my main problem here is I don't know what any of this is called; I can't find any reference to the in-call status bar in any of the documentation except where it talks about the simulator menu command.)

Answer 1

You're looking for -[UIApplication statusBarFrame] and, in your UIApplicationDelegate, you should implement this delegate method to be notified of when the status bar's frame changes:

- (void)application:(UIApplication *)application didChangeStatusBarFrame:(CGRect)oldStatusBarFrame

Answer 2

What do you mean when you say that 'the resize properties aren't enabled for the root UIView'?

The in-call status bar doesn't have any particular special designation, and I don't think there are any APIs or notifications around it. Instead, your views should simply be set up to autoresize correctly.

Try creating a new navigation-based app in Xcode and study the autoresize settings on the table view in RootViewController.xib. Hopefully you'll see a delta between what Apple's set and what you've set in your project.

Answer 3

For views like UITableView you'll typically need to change the table cell height, and there's no other way to do it except to implement application:didChangeStatusBarFrame:. But it's no biggie, and you can set the row height to non-integer values if you need to.

Answer 4

The solution is to ensure you have made your window key:

[window makeKeyAndVisible];

If you don't do that the subview does not get resized automatically, but there are no other symptoms as far as I know.
