Answer 1

Options:

1) Create a model object either as a singleton or owned by the app delegate. Update it in the second controller. Load and display it when the view of the first controller appears.

2) Have the second controller send a notification when the button is clicked and attach the text as the notification's object. Put code in the first controller to listen for the notification and use the attached text.

Answer 2

I second Phillip's answer.

However, I would suggest using an NSLocalNotification and avoiding using a Singleton. From what you've described the notification would do the trick just fine, where as the Singleton would be overkill.
