Depending on the size and complexity of the dataset you can use Core Data or a property list. For Core Data see the examples mentioned in the documentation (look for NSManagedObjectContext class).

For property lists use [NSKeyedArchiver archiveRootObject:myArray toFile:path] to save an array to disk.

The folder to store the file at can be determined with:

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
