With the coming update, our iOS app is supposed to export data to a text file in the iCloud and to import data from it. The implementation is mostly completed and we started beta-testing. Everything seems to be working fine for all but one of the beta-testers.

What I gather from debugging output collected by the TestFlight API, one of the testers somehow managed to get the file into the UIDocumentStateSavingError state. So far, we could not manage to pop the file out of that state no matter what we had him try.

This is what happens on the tester's device:

  • iCloud access is successfully detected using URLForUbiquityContainerIdentifier.
  • An NSMetadataQuery is started to locate the file and returns exactly one result.
  • An subclass of UIDocument is created for the resulting URL using initWithFileURL:.
  • The document is in the UIDocumentStateSavingError state. Also, this is the only state flag that is set.
  • The call to openWithCompletionHandler: returns failure to the handler and loadFromContents:ofType:error: on the UIDocument is not called.

We then made a new version of the app that continues as follows:

  • The app tries to delete the erroneous file using [[NSFileManager defaultManager] removeItemAtURL:doc.fileURL error:&err].
  • The resulting NSError indicates that "The operation couldn’t be completed. No such file or directory".

Deleting the file was about the last thing we could come up with in order to resolve the file's state. Any hints on how to solve this or on what might be causing the error in the first place would be very much appreciated!

  • Thanks for the hint, it actually might. I'll check on that when I find the time. – cg. Mar 29 '12 at 13:21
  • It has been a long time but I am curious if you ever found a solution? – Daniel Galasko Sep 03 '20 at 09:22
