Question

need to save some persistent data. the data would only contain 3 or 4 arrays with 100-200 single value entries.

(array) data
(
  (
    (dictionary) key -> value
  )
  (
    (dictionary) key -> value
  (
  //etc
)

these are just simple lists to show in pickers.

so far i’ve used NSUserDefault to store single dictionary values, and i’m wondering if it would suffice for this new data or do i need to consider using Core Data?

at this point in time, i don’t see my program needing to sore more data then this.

Answer 1

Really depends on task.

You should answer on these questions:

1. How often this data should be changed?
2. How often this data should be queried ?
3. What kind of queries do you want to use on this data?

As far as I see, if you just need to show them in pickers, you obviously can use NSUserDefaults, or plist file to save this data between launches.

And NSArray/NSDictionary to use it in app.
