How to play system button click sound on iPad?

Question

I need to play some system sound when users click button in my application which is running on iPad. How to implement it in iOS?

Answer 1

If you want to play a short sound (shorter than 30 sec), you can do it easily like this:

Note: You'll have to add AudioToolbox framework and import it (#import <AudioToolbox/AudioToolbox.h>)

SystemSoundID mySSID;

NSString *path = [[NSBundle mainBundle] pathForResource:@"beep" ofType:@"wav"];
AudioServicesCreateSystemSoundID((CFURLRef)[NSURL fileURLWithPath: path], &mySSID); 

AudioServicesPlaySystemSound(mySSID);

Also note that the file can be:

• No longer than 30 seconds in duration
• In linear PCM or IMA4 (IMA/ADPCM) format
• Packaged in a .caf, .aif, or .wav file

Answer 2

You should use AVAudioPlayer.

There's a great tutorial here on using AVAudioPlayer to play sounds. A very simple example of it's use:

NSURL *url = [NSURL fileURLWithPath:[NSString stringWithFormat:@"%@/audiofile.mp3",dataPath];

NSError *error;
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error];

if (audioPlayer == nil)
    NSLog([error description]);
else
    [audioPlayer play];
