how to deal with (A Document being saved by MyApp) files?

Question

My application uses iCloud. My application stores all its data in 1 document and there should never be more than this 1 document. However, sometimes my NSMetadataQuery returns 2 documents:

0: Documents/(A Document being saved bt MyApp)/MyDoc.ext
1: Documents/MyDoc.ext

This happens mostly when the user opens the app shortly after the iOS device was rebooted.

When inspecting these 2 docs, it is document 0 that is the one with the most recent updates, so this is the one we want.

What is the reason of this "A Document Being Saved" ending up there and being the most recent one and how do I deal with this correctly, so Documents/MyDoc.ext will be the one that has the most recent content.

Thanks, -r

I think Stuart's comment provides most of the answer you'll get. The fact alone that the document is called "(A Document Being Saved by )" and not "(A Document Saved by ) strongly suggests he's right.
I guess it's now up to you to figure out why saving the document crashes or never finishes or gets terminated or whatever. It could be a timeout, if your app takes too long saving the document when going to the background, a crash, or something else - I don't think you've provided enough information for anyone to give you a really precise answer.
