I'd like to use the features of NSUserDefaults for saving state. I do currently have that working. But I want to copy this plist file and apply it to the same app on another device. 

Is there some way to pass a file name to NSUserDefaults or do I need to use some other class? Or is it fine to share the plist with the same app another device?

The app on device1 and device2 is the same app. I'm not trying to share data between different apps.
