title: ios 7 simulator wouldn't fallback user interface for apps compiled against ios 6.1 sdk
body: <p>Our ios6.1-sdk-compiled app has been running fine on ios 6.1 iphone 4, 4s &amp; 5 devices. When running the app on ios7 iphone 5s the user interface still looks like ios 6 (black buttons etc) but we're fine with most of it, except we found a bug. I'm guessing this is because changes on API implementation on ios7. </p>
  
  <p>When our app is compiled against ios7-sdk on xcode 5 everything falls apart. UI objects are misaligned, label's can't be read etc. Hence we want to compile our code against ios6.1 sdk but run it on ios 7.</p>
  
  <p>On Xcode 5 I've installed ios 6.1 sdk <a href="https://stackoverflow.com/questions/12523888/how-can-i-add-older-version-of-ios-sdk-in-xcode-4-5">by copying it from Xcode 4.6.3 dmg as described on this post</a> and updated Base SDK to ios 6.1 on build settings, however when running the app on ios 7 simulator the user interface wouldn't fall back to ios 6.1. It does however fall back to ios 6.1 if the app is tested against a physical iphone running ios 7.</p>
  
  <p>How can I make ios 7 simulator falls back user interface when running ios6-sdk-compiled apps so we can reproduce the bug on simulator?</p>
