Ios settings bundle not updating

how do i get the textfield to automatically update from the settings bundle and not just one way this is the code i am using in the view did load Utlized notification to fire up ui Application Will Enter Foreground Notificion from the delegate, this is called whenever the app is brought into the foreground, i then set the selector to a method i implemented in my own class file called update My Tex, this method updated the required textfield.
