Play a short sound in iOS

by

Every single one of the other answers leaks memory (unless ARC is enabled for one of the answers)… oddly, the answer originally marked as correct has a call to retainCount for no apparent reason.

If you alloc/init something, it needs to be released (unless you are using ARC).

If you call AudioServicesCreateSystemSoundID() you have to dispose of the resulting sound.

See the Audio UI Sounds example.

Basically:

@interface MyClass:UI*ViewController // fixed
{
     SystemSoundID mySound;
}
@implementation MyClass
- (void) viewDidLoad {
    [super viewDidLoad];
    AudioServicesCreateSystemSoundID(.... URL ...., &mySound);
}

- (void) playMySoundLikeRightNowReally {
    AudioServicesPlaySystemSound(mySound);
}

- (void) dealloc {
   AudioServicesDisposeSystemSoundID(mySound);
   [super dealloc]; // only in manual retain/release, delete for ARC
}
@end

For completeness:
add AudioToolbox.framework
#import <AudioToolbox/AudioToolbox.h>
