I have an App that was created a long time ago and updated it to use Storyboards. All the views have been rebuilt and hooked up. However, the App does not use the entire h
Your app has been compiled with iOS 5 or earlier and you are viewing it on a device with iOS 6 or up.
set target of your application as iOS 7 in Xcode and use Auto layout constraints to make it work on both devices. I will suggest you to have multiple storyboard if you want to support iOS 5 or earlier because they don't have auto layout constraints.
You need to compile your code with iOS 6 + SDK and use Auto layout constraints.
//Edit: if you are already using iOS 6+ as your deployment target for your project
If your iOS is set to 6 and up check your storyboard settings if your storyboard's deployment target is iOS 6 and up.
