If you have a strange problem like your iOS 7 with XCode 5 has shifted here or there and have been really annoyed? Don’t panic.
All you need to do is compile your code with iOS 6 SDK but on XCode 5. The bad thing is that you’ll not get iOS 7 only features (Which at the moment you may not need because you need to obviously support iOS 6), so here’s the trick:
Step 1: Import iOS 6 SDK into XCode 5

Step 2: Restart your XCode 5
Step3: After that please change your settings to Project > Build Settings > Architecture  > BaseSDK > iOS 6.1
Step 4:  Clean and Build
Use Xcode with iOS 6 SDK
