Run NSOperation on Main Thread

I built a NSOperation to run on a background 开发者_Go百科thread, but I have since optimized the operation such that I might be better suited running it in the main thread. Is there a way to direct my NSOperation to run on the main thread instead of a background thread so that I can test things out without significant refactoring?

You can do this in the NSOperationQueue by using mainQueue
