    From the apple documentation for addOperation: it is clear that you cannot add an operation which is executing into a NSOperationQueue.

    This is what mentioned there,

    An operation object can be in at most one operation queue at a time and this method throws an NSInvalidArgumentException exception if the operation is already in another queue. Similarly, this method throws an NSInvalidArgumentException exception if the operation is currently executing or has already finished executing.

    That is the default behavior of NSOperationQueue. You need to make sure that the NSOperation is not executing before adding to queue. There are various properties such as isExecuting, isFinished etc.. to check this.
