I am making an iOS app in which I need the user to be able to add a multiple names. These names will then be stored and displayed 1 at a time in a label. When the device is shaked the label will then display the next name in the list. I have looked into Core Data and NSArrays but i don't know the best way of doing this?
Thanks

If you only need those names to be stored for a short period of time (the app's execution time, for instance) use NSArray-s, if you want the data to persist, even if you close the app, then you should save it with Core Data, or, more simple, with NSUserDefaults.
Hope it helped you somehow :)

Can the names be put in by the user using a text field and then edited at a later date?
Thanks

6,535 PointsNot sure if I understand correctly you question, but I think you want to create the names during the app's execution, right? Yes, it's possible. Make sure you use NSMutableArray for that.

1,331 PointsIf I store the list in an array will the list be deleted if the app is in the background whilst multitasking?
Pavel Palancica
6,535 PointsYes, it should be in memory and available for using the data inside it, even if the app goes into background (if using multitasking).
