I just finished writing a new article for Cocoa Is My Girlfriend. I am building on the work Marcus did on his first article called Cocoa Tutorial: NSOperation and NSOperationQueue. In my article I’m taking a slightly more practical approach where I provide a flicker free method for grabbing images from a currently playing QuickTime movie. The NSOperation grabs the image data from the movie and saves it out to a folder in the filesystem specified by the user.
I think it is pretty cool. I hope it will help others see the power and flexibility of NSOperation and NSOperationQueue.
