I am currently in the early stages of learning how to build a basic iPhone app with Xcode. I read where the easiest way to learn is to watch Youtube apps on Xcoding. I took that advice and found a video by Matt Heaney on how to build a simple helicopter game. I completed his 3 video series and built my own copter game using a sub instead. But now I want to learn how I can add sound to my new app. Does anyone know where I can go to learn how to add a simple audio file to my newly created app? I've looked on line, and so far I have not come across a good source. Any help would be appreciated. Thank you. PS - Also, I started to do the same game for the iPad, but kept running into an error that says something like I don't have an identifier, or entry points. Do I have to have an Apple Developer Account to be able to make an iPad app, or is my problem something else?
