2) Click on the Build Phases tab in the main panel
3) Click on the + in the Link Binary with Libraries section 
4) Select the AVFoundation.framework and click on the Add button


*** Step 2: ***

Inside your ViewController.h file:

#import <AVFoundation/AVFoundation.h> 

@interface ViewController : UIViewController

@property (strong, nonatomic) AVAudioPlayer *audioPlayer;


*** Step 3: ***

Inside your ViewController.m file:
(probably inside your viewDidLoad method)
(replace @"MyFilename" with the filename)


NSURL *url = [NSURL fileURLWithPath:
      [[NSBundle mainBundle] pathForResource:@"MyFilename" ofType:@"mp3"]]; 

NSError *error;

_audioPlayer = [[AVAudioPlayer alloc] 
       initWithContentsOfURL:url error:&error]; 


if (error) 
{ 
    NSLog(@"Error in AudioPlayer"); 
} 
else 
{
    [_audioPlayer prepareToPlay];
	[_audioPlayer play]; 
}


How to play an audio file in iOS5

#import <AVFoundation/AVFoundation.h>
// you need to add the AudioToolbox.framework to use this
// and you need to add the sound files to the project
#include <AudioToolbox/AudioToolbox.h>

// this is for playing mp3's etc.
// define these variables in your .h file
AVAudioPlayer *player;
NSString *pathForExplosionSound;

// use this code for setting up the player
pathForExplosionSound = [[NSBundle mainBundle] pathForResource:@"explosion" ofType:@"mp3"];

NSError *error;

if (![[NSFileManager defaultManager] fileExistsAtPath:self.pathForExplosionSound])
return NO;

player = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:self.pathForExplosionSound] error:&error];

[player prepareToPlay];

// methods to call
[player play];

[player pause];

// use this to reset it (don't call stop)
if ([player isPlaying]==YES)
[player setCurrentTime:0];

// stops the player and releases it from memory
[player stop];

// use this to reset it
[player setCurrentTime:0];

// Don't forget to release it
// at the very end
// since we did an alloc
[player release];

@interface ViewController : UIViewController 

@property (strong, nonatomic) AVAudioPlayer *audioPlayer;


*** Step 3: ***

Inside your ViewController.m file:
(probably inside your viewDidLoad method)


NSURL *url = [NSURL fileURLWithPath:
      [[NSBundle mainBundle] pathForResource:@"MyFilename" ofType:@"mp3"]]; 

NSError *error;

       initWithContentsOfURL:url error:&error]; 


if (error)

} 
else 
{
    _audioPlayer.delegate = self; 
    [_audioPlayer prepareToPlay];
	[_audioPlayer play];
}


*** Step 4: ***

You can add these methods to the ViewController.m file:

-(void)audioPlayerDidFinishPlaying: (AVAudioPlayer *)player successfully:(BOOL)flag 
{ 

} 

-(void)audioPlayerDecodeErrorDidOccur: (AVAudioPlayer *)player error:(NSError *)error 
{ 

} 

-(void)audioPlayerBeginInterruption:(AVAudioPlayer *)player 
{ 

} 

-(void)audioPlayerEndInterruption:(AVAudioPlayer *)player 
{
