[[NSSound soundNamed:@"Hero"] play];

There are some predefined system sounds, for the system sound ID in the range 1000 to 2000 (decimal), as shown below (from 2.0 to 5.0 beta). The system sounds are all stored in

SystemSoundID myAlertSound;
NSURL *url = [NSURL URLWithString:@"/System/Library/Audio/UISounds/begin_video_record.caf"];
AudioServicesCreateSystemSoundID((__bridge CFURLRef)(url), &myAlertSound);
AudioServicesPlaySystemSound(myAlertSound);

NSString *path = [[NSBundle bundleWithIdentifier:@"com.apple.UIKit"] pathForResource:@"Tock" ofType:@"aiff"];
if (path) {
SystemSoundID theSoundID;
OSStatus error = AudioServicesCreateSystemSoundID((__bridge CFURLRef)[NSURL fileURLWithPath:path], &theSoundID);
if (error == kAudioServicesNoError) {
AudioServicesPlaySystemSound(theSoundID);
}else{
NSLog(@"Failed to create sound ");
}
