controlling user in iphone

Question

Hey guys,

I don't know anything about how to control the user for accessing music (I have 80 to 90 songs in my application) but I want the user to access only 3 songs when the user downloads my application. These 3 songs must be available for one day only - after that it is locked for the user (the user didn't have permission to access the music) until the user logs in.

Help me out from this give hint to solve this.

Answer 1

Add a database to your app (core data/sqlite). Add a reference to your songs along with a Date field, and tracking field. When a song is requested for play add date stamp in database. Check date stamp, if date stamp is greater than 24 hours old, present alert message to user. You can check either the tracking field (number of times played) or date field.
