Create a thread to be added with NSInvocationOperation what framework it

NSInvocationOperation * theOp = [[NSInvocationOperation alloc] initWithTarget: self selector: @ selector (myTaskMethod :) object: data];

[[MyAppDelegate sharedOperationQueue] addOperation: theOp];
Why sharedOperationQueue This method shows not found, is the need to add any framework, or do something else.
