What is meant by .delegate=self? http://stackoverflow.com/questions/4211947/what-is-meant-by-delegate-self such delegates. In the example of flying above somewhere in the code for flying it would have to say UIAccelerometer sharedAccelerometer setDelegate self . Note that UIAccelerometer is a singleton. In the case of bigTop it would have to set the delegate somewhere..
