I am building an alarm app using local notifications.
I want to add settings inside my app.
So for this I have created the whole view,now I am confused how to store data for multiple alarms?
Whether i should use NSUserDefaults or sqlite.
You have all the choices:
a) Use NSUserDefaults by doing some simple Key amendments like with keys like SettingAttr = Value, e.g. “MyAlarm0Start” = 10:23:12, “MyAlarm1Start” = … and for instance the number “MyAlarmCount” = 2
or use
b) a complete data model by CoreDate or SqlLite.
I think this strongly depends on how much data you want to store.
Concerning iTunes library am do not understand what you wanted to know.
Edit: Picking things from your media library is handled via the “Media Player Framework”, see Apple Doc IPod Library Access.
