Verifying if a MCOOperation has finished, not canceled but finished.

Verifying if a MCOOperation has finished, not canceled but finished.

Hey there,

I was wondering if there was a way to verify if an MCOOperation has 
finished or not. I ask because I’ve had issues where I think a number of 
the MCOOperations I’ve kicked off never have their completion blocks 
called and I would like to have some code that checks the MCOOperations 
that I’ve spawned and validate if there is a problem or not.
