    Please, read documentation.

    https://developer.apple.com/library/mac/#documentation/Cocoa/Reference/NSOperationQueue_class/Reference/Reference.html

    • (void)addOperation:(NSOperation *)operation

    Parameters

    operation

    The operation object to be added to the queue. In memory-managed applications, this object is retained by the operation queue. In
    garbage-collected applications, the queue strongly references the
    operation object.

    Discussion

    Once added, the specified operation remains in the queue until it
    finishes executing.
