iphone - Best ways to play simple sound effect in iOS

Question

I'm finding a number of conflicting data about playing sounds in iOS. What is a recommended way to play just a simple "ping" sound bite every time the user touches the screen?

Answer 1

I use this:

Header file:

#import <AudioToolbox/AudioServices.h>

@interface SoundEffect : NSObject
{
    SystemSoundID soundID;
}

- (id)initWithSoundNamed:(NSString *)filename;
- (void)play;

@end

Source file:

#import "SoundEffect.h"

@implementation SoundEffect

- (id)initWithSoundNamed:(NSString *)filename
{
    if ((self = [super init]))
    {
        NSURL *fileURL = [[NSBundle mainBundle] URLForResource:filename withExtension:nil];
        if (fileURL != nil)
        {
            SystemSoundID theSoundID;
            OSStatus error = AudioServicesCreateSystemSoundID((__bridge CFURLRef)fileURL, &theSoundID);
            if (error == kAudioServicesNoError)
                soundID = theSoundID;
        }
    }
    return self;
}

- (void)dealloc
{
    AudioServicesDisposeSystemSoundID(soundID);
}

- (void)play
{
    AudioServicesPlaySystemSound(soundID);
}

@end

You will need to create an instance of SoundEffect and direct call the method play on it.
