title: UITextView with attributed text in iOS 6.1 with base SDK iOS 6.1 doesn't work
body: <p>My App uses deployment target 5.0, Base SDK 6.1, XCode 5 and runs on a device with iOS 7. I have a <code>UITextView</code> with Attributed text in my Storyboard (edited the attributed text in the Storyboard). </p>
  
  <p>My problem is that I only see the attributed text when I build with base SDK 7.0. On 6.1 or 6.0 (in the simulator) I do not see the attributed text, while it should be supported from 6.0+ (before iOS 7 and XCode 5, it worked). I get the warnings on my storyboard (correctly) that "Attributed Text on iOS versions prior to 6.0", but this shouldn't keep iOS 6.0 from displaying Attributed text, right?</p>
