Stephen Ball from Embarcadero has a post up where he implements full screen mode for IOS apps built with Delphi XE7 Firemonkey. Basically TForm has a FullScreen property which you can set that sets your application to full screen depending on the platform. On Windows (and probably OSX) the app takes up the entire screen. On Android it turns off the notification bar at the top of the screen. But on IOS currently the Fullscreen property doesn’t make any changes. What Stephen created was a new interface which upgrades the Fullscreen property so that on IOS it also goes into full screen mode (by changing the form border style). The interface is like a class helper because it injects itself into the existing functionality and changes it so that your code stays the same but has new functionality. The blog post also explains how to create interfaces like this for your own use. All of this code also works under Appmethod of coarse.
