NSSound on the iphone

Question

I've been looking for a while how to play sound on the iphone, and I think it's something along the lines of:

[[NSSound soundNamed:@"cat.mp3"] play];

But the NSSound is on the AppKit ... any suggestions ? I know there is a really simple answer to this, but today my searches are not rendering any result ...

Answer 1

Audio Toolbox system sounds are great for short async playback.

// Initialize
CFBundleRef mainBundle;
mainBundle = CFBundleGetMainBundle ();

// Init each sound
CFURLRef      tapURL;
SystemSoundID tapSound;
tapURL = CFBundleCopyResourceURL(mainBundle, CFSTR("tap"), CFSTR("aif"), NULL);
AudioServicesCreateSystemSoundID(tapURL, &tapSound);

// Play the sound async
AudioServicesPlaySystemSound(tapSound);

I haven't gotten MP3s to work with AudioServicesPlaySystemSound. But it plays AIF files perfectly.

Answer 2

the new AVFoundation class is the easiest way to play sound on the iPhone, though it is for firmware 2.2 only:

AVAudioPlayer *audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL];  
[audioPlayer play];

you just need this import in the class that uses it:

#import <AVFoundation/AVAudioPlayer.h>

Answer 3

...any chance that this framework allows the app to control playback speed? something along the lines of speeding up the tempo on a song?

Thanks!
