So they
Hi Shane,
NSOperationQueue will not let you re-run a previously run NSOperation Object.
What I did to get around the problem was to create my own NSObject that does
what I want. I then wrapped the object with an NSOperation object to run. Once
complete, I can simply re-use my NSObject by wrappin
From the docs for NSOperation:
... "An operation object is a single-shot object—that is, it executes its task
once and cannot be used to execute it again."

I have an NSOperation object that has been placed in an
NSOperationQueue. I then execute that NSOperation and all works
normal.
What I'd like to do is then run that task again, however, when I do
run it I get the following error when trying to add that object to the
queue again.
Caught NSInvalid
