I'm looking to build an incredibly simple application for iOS with a button that starts and stops an audio signal. The signal is just going to be a sine wave, and it's going to check my model (an instance variable for the volume) throughout its playback and change its volume accordingly.

My difficulty has to do with the indefinite nature of the task. I understand how to build tables, fill them with data, respond to button presses, and so on; however, when it comes to just having something continue on indefinitely (in this case, a sound), I'm a little stuck! Any pointers would be terrific!

Thanks for reading.
