   Hi, I want to use the SimpleAudioEngine to play background music in my game, i wrote my code like this:

   [[SimpleAudioEngine sharedEngine] playBackgroundMusic:@"bg"];

   when i test, there is an error says : .objc_class_name_SimpleAudioEngine, referenced from:

   it seems i did not include the framework in the right way. besides, i see in the api that it needs AVFoundation.framework, but i can't find it.

   can somebody tell me how to do this? where can i find some tutorials for this SimpleAudioEngine?
   thanks a lot

   first off, you should include the extenstion in the file name e.g. @"bg.caf"
   There are known issues with AVFoundation framework, google it...
   You should add the framework from this path:

   /Developer/platforms/iphone.os/SDK/Library/Frameworks

   Should be something simillar, sorry if I forgot one of folders. You can search for the framework on your computer (thought of that?).
