Hey all, I'm Matt. I'm new to the forum, but I'll get right down to my problem. I am trying to make a simple application to play songs from the iPod library. Currently, there are two buttons on the form; one is to select a song, which will start playing after you select it. The second is to pause or play the song, depending on the current playback state. My problem is, when I do anything, the app will crash. This includes selecting a new song, pausing/playing the song, even adjusting the volume with the outside buttons. I have included the program in this thread so you guys can take a look. Thanks much for any help you can provide! EDIT: Forgot to mention, I'm running on an iPhone 3G, 3.1.3. And no, I am not compiling for iPhone 3.2. Thanks!
