How the apps already build for iPhone 4 and 5 will shown in iPhone 6 and 6 plus

Question

As the apple has announced the two more screen sizes iPhone 6 and 6 plus. What will happen to apps already in app store build for iPhone 4 and 5. Will they be stretched or t

Answer 1

If you have uploaded apps from XCode 5.x apple will take care and they will be scaled and stretched to fit them in iPhone and iPhone 6. If you want to take advantage of new devices you will have to use XCode 6 and add launch images on your project with these steps.

If you have not added launch images for iPhone 6 and 6 plus (and do not have Launch Screen File for iOS 8) , than your apps will be streached to fit in new devices , once you add them app will not be streached and you will have to manage it.

So with Xcode 5.x , you can be absoulatly sure that iOS will take care and streach your app to look just like thy look in iPhone 5 or 5S.
