Using system Sound to play sounds
- by Shoaibi
Here is the code:
-(void)stop
{
NSLog(@"Disposing Sounds");
AudioServicesDisposeSystemSoundID (soundID);
//AudioServicesRemoveSystemSoundCompletion (soundID);
}
static void completionCallback (SystemSoundID mySSID, void* myself) {
NSLog(@"completion Callback");
}
- (void) playall: (id) sender {
[self stop];
AudioServicesAddSystemSoundCompletion (soundID,NULL,NULL,
completionCallback,
(void*) self);
OSStatus err = kAudioServicesNoError;
NSString *aiffPath = [[NSBundle mainBundle] pathForResource:@"slide1" ofType:@"m4a"];
NSURL *aiffURL = [NSURL fileURLWithPath:aiffPath];
err = AudioServicesCreateSystemSoundID((CFURLRef) aiffURL, &soundID);
AudioServicesPlaySystemSound (soundID);
NSLog(@"Done Playing");
}
Output:
Disposing Sounds
Done Playing
In actual no sound gets play at all and completion call back isn't called as well. Any idea what could be wrong here?
I want to stop any previous sound before playing current.
