openWithCompletionHandler prob in 5.1 sim

问题

I'm puzzled. I'm finding that the UIDocument method openWithCompletionHandler works in the iOS 5 and IOS 6 sims, but not in the one for iOS 5.1.

Any thoughts on how I work around this? Is it just one of those things where the sim falls down but the real environment doesn't?

Thanks.

Steve

I see something similar. In openWithCompletionHandler the completion handler is never called. In saveToURL, the app freezes completely. As for you this only happens in the 5.1 simulator. 5.0 and now 6.1 are fine.
