Can I use iCloud to sync the NSUserDefaults plist file

ios cocoa-touch ios5 sync icloud

I was wondering if it was possible to use iCloud to sync an app's preferences file between devices. The preference file I am talking about is the com.domain.appname.plist file created by NSUserDafults to store the app's preferences.

I would like to have the option of keeping my app's preferences file in sync between two different devices (an iPad and an iPhone, for example). Is this an acceptable use of iCloud syncing? Or would I need to convert the plist file into a different type of document, store it on the cloud, and convert it back into the app's preferences file upon retrieving it?

thanks!

Similar to MKiCloudSync, I also have a library on GitHub called SDCloudDefaults. Rather than sync automatically, there's a new object that you use instead of NSUserDefaults that saves to both iCloud and NSUserDefaults. This means you can decide which elements are stored locally and which are stored in the cloud.

(I found MKiCloudSync after I'd implemented it. I think it's clever but I don't want to sync everything to iCloud so my solution still works better for me.)
