A quick google appeared:

• Concurrency Programming Guide for Operations and Threads.
• NSOperationQueue class reference
• An example (aptly named) of the NSOperationSample , straight from Apple, and
• a descriptive post from the excellent Cocoa Is My Girlfriend blog with a small, well-explained example, with snippet code.
