StatusBarHidden - ParkinT/RubyMotion_Life GitHub Wiki

You can set the StatusBar (the black bar at the top) to be hidden, while your application is running, with this command

UIApplication.sharedApplication.setStatusBarHidden true, animated:false

But suppose you want the app to load with no visible StatusBar initially? That requires a PList entry.

Add this to your Rakefile in the Motion::Project::App.setup block

app.info_plist['UIStatusBarHidden'] = true
