title: My iOS App is having a Black Screen after Splash Screen, but it shows the status bar. iOS SDK 5.1
body: <p>I am using the Tab Bar View App, and am using a storyboard, my Xcode Version is 4.3.3.
  Basically my app used to load fine, but then I added a third view and third view controllers and it wouldn't load properly so I deleted them and now it won't load properly:/ It loads the splash screen but it doesn't go any further.</p>
  
  <p>Here is my AppDelegate.h</p>
