title: although ios 6.1 as base sdk xcode 5 build ipa for ios 7
body: <p>i changed the base sdk for iOS 6.1 in xcode 5 .</p>
  
  <p>When i simulate my project on a iOS 6.1 simulator or on a iOS 6.1 device
  all works fine. But when i build a ipa and install it on a iOS 7 device
  the device use the iOS 7 sdk and my hole app looks weird. I changed my base
  sdk for iOS 6.1, so why use my device the iOS 7 sdk?</p>
  
  <p>I read that iOS 7 use the iOS 6.1 sdk for old published apps.
  What do i have to do that iOS 7 also do that for my app?
  My only idea is to install xcode 4 again...</p>
