问题 Will the UIApplicationDelegate call performFetchWithCompletionHandler if device is not connected to the internet ?

问题 My app is crashing any time I present a UIActivityViewController , only on iOS9. I've isolated the code down to this: (Cleared everything from the AppDelegate minus setting my test view controller as the root and only VC).

I'm more inclined to believe this is an issue with memory exhaustion more specifically and possible virtual memory exhaustion.

I don't know enough about iOS internals to entirely what's going on here but wondering if there's others out there who have
