How to play an Audio Alert

Just like playing a standard sound file, you can also choose to play an alert. The difference is that this will make the iPhone vibrate if it’s set to silent. The code is nearly identical to the standard sound file with the exception of the very last line of code:

SystemSoundID soundID;
NSString *soundFile = [[NSBundle mainBundle]pathForResource:@"yourfile" ofType:@"wav"];
AudioServicesCreateSystemSoundID((__bridge CFURLRef)[NSURL fileURLWithPath:soundFile], &soundID);
AudioServicesPlayAlertSound(soundID);

This snippet assumes you’re using a file called yourfile.wav which needs to present in your project. You’ll also need to import the AudioToolbox Framework and import it in your header file.
