Question

I am currently trying out this code:

NSString *path = [[NSBundle mainBundle] pathForResource:@'dream' ofType:@'m4a'];   AVAudioPlayer* theAudio=[[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL];   theAudio.delegate = self;   [theAudio play]; 

However, the SDK says that the ViewController does not implement the AVAudioPlayer Delegate.

Any body any ideas on how to play a WAV (or M4a) using the 2.2 SDK?

Answer 1

You need to add <AVAudioPlayerDelegate> to the end of your controller’s class declaration, along these lines:

 @interface MyViewController : UIViewController <AVAudioPlayerDelegate> 

This’ll probably generate some more warnings about delegate methods you need to implement – follow those and you’ll be good to go.
