I am doing a test tonight as I am learning the iPhone. Is the saving system the same as creating an application on the OS X platform? I have 3 columns and many rows in the photo shown. I would save each colums as an NSArray containing NSStrings. Then take the 3 NSArrays and save them into an NSDictionary which I then write to a plist file which I save in the Documents Directory in my Sandbox on the iPhone. Is my understanding correct?
