The dealloc method gets called when the controller is being removed from memory. This method is called when the controller is about to be removed from existence (you should release everything and perform general cleanup).

The viewDidUnload method is called when the view is being destroyed. After this method is called the controller may continue to exist. In this method you should release anything that supports the view and that is no longer needed.

If you would like to see exactly when they are called you can put in NSLog() statements and monitor the log.
