Question

I need store just 10 arrays in my app, which I can change from time to time. What would the best way to do this be?

I have been looking into writing to a plist, is this a good idea?

Each of the 10 arrays will have 10 objects (just strings).

Answer 1

You could create an NSDictionary (or rather the mutable version in your case) and populate it with your arrays. Then you could write them to disk with

writeToFile:atomically:

At start you could check whether your path is valid (meaning your dict exists) and assign it to your iVar in code for example with

initWithContentsOfFile:

The advantage is that the underlying representation is a plist for the NSDictionary (or NSMutableDictionary). So you are good to go here as well and as your objects within the arrays conform to NSCoding they all know how to encode them for writing to disk.
