Toggle In-Call Status Bar. Toggles the status bar between its normal state and its in-call state. The status bar is taller in its in-call state than in its normal state. This command shows you how your application’s user interface looks when the user launches your application while a phone call is in progress.
Just run your application in the simulator and then go to Hardware->Toggle In-Call Status Bar. The Status Bar will grow. Pick the same menu option to get the Status Bar back to its original size.
Always try to keep the layout of the subviews of a container flexible. Using the autoresizing feature is a good approach.
