Can a single instance of a UIDocument not be opened and closed multiple times? It seems that I can open, close, and re-open a document, but as soon as I try to call closeWithCompletionHandler: on it a second time I get an exception:
Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'closeWithCompletionHandler called while document is already closing'
Prior to the call the documentState is Normal.
Hopefully I’m just overlooking something obvious…
Instead of re-opening a closed document with openWithCompletionHandler, create a fresh UIDocument subclass instance and initialize it first with initWithFileURL and then open it.
