title: iOS7 automatically sets the button to “Back” instead of previous screen’s title
body: <p>My app is supposed to run both on iOS 7 and iOS 6 but I am seeing a bit of different behavior with iOS 7. As per my observations iOS7 automatically sets the button to “Back” instead of previous screen’s title when the title is too long. Has anyone faced the same issue. Any clue?</p>
  
  <p>iOS 6 --> Back button title reads "Customer Details" and screen title is "Details"
  iOS 7 --> Back button title reads "Back" and screen title is "Details"</p>
