Alarm Date Picker Xcode

We have an app that user a date picker to set the alarm in the third view. It was responding in xcode 4.2 and updating the first view and setting the alarm. Since xcode 4.5 we are unable to get the alarm to set and update the first view. Once fixed, also want the alarm to play in background mode. There is a radio contained in the app that is set up and works in background mode. Many thanks for the interest.
