I have a very simple app that is supposed to only play an audio file on view. Instead my Xcode is crashing.
I am using Xcode version 6. I have implemented the AVFoundation Framework
- (void)viewDidLoad
{
[super viewDidLoad];
NSString *audioPath = [[NSBundle mainBundle] pathForResource:#"Crowd_cheering"
ofType:#"m4a" ];
NSURL *audioURL = [NSURL fileURLWithPath:audioPath];
NSError *error;
self.player = [[AVAudioPlayer alloc] initWithContentsOfURL:audioURL error:&error];
[self.player play];
}
//Try like this with error condition:
NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle]
pathForResource:#"Moderato"
ofType:#"mp3"]];
NSError *error;
_audioPlayer = [[AVAudioPlayer alloc]
initWithContentsOfURL:url
error:&error];
if (error)
{
NSLog(#"Error in audioPlayer: %#",
[error localizedDescription]);
} else {
_audioPlayer.delegate = self;
[_audioPlayer prepareToPlay];
}
//Before that add import AVFoundation/AVFoundation.h and add delegate AVAudioPlayerDelegate
//then Implement the AVAudioPlayerDelegate Protocol Methods like this
-(void)audioPlayerDidFinishPlaying:(AVAudioPlayer *)player successfully:(BOOL)flag
{
}
-(void)audioPlayerDecodeErrorDidOccur:(AVAudioPlayer *)player error:(NSError *)error
{
}
-(void)audioPlayerBeginInterruption:(AVAudioPlayer *)player
{
}
-(void)audioPlayerEndInterruption:(AVAudioPlayer *)player
{
}
Make sure u connected ur play button properly or not and also check whether you Added an Audio File to the Project Resources properly.

My app has looped background music that plays over the initial view controller.
- (void)viewDidLoad {
[super viewDidLoad];
NSURL *url = [NSURL fileURLWithPath: [NSString stringWithFormat:#"%#/bgMusic.mp3", [[NSBundle mainBundle] resourcePath]]];
NSError *error;
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error];
audioPlayer.numberOfLoops = -1;
[audioPlayer play];
}
When leaving the initial view controller I want the music to stop, so I used the code below, but instead it restarts.
- (void)viewWillDisappear:(BOOL)animated
{
[super viewWillDisappear:animated];
[audioPlayer stop];
}
In my viewcontroller.h file I have:
- (void)startBackgroundMusic;
- (void)stopBackgroundMusic;
#property (strong, nonatomic) AVAudioPlayer *audioPlayer;
In my viewcontroller.m I have:
- (void)startBackgroundMusic
{
NSError *err;
NSURL *file = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:#" DK" ofType:#"mp3"]];
_audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:file error:&err];
if (err) {
NSLog(#"error in audio play %#",[err userInfo]);
return;
}
[_audioPlayer prepareToPlay];
_audioPlayer.numberOfLoops = -1;
[_audioPlayer setVolume:.5];
[_audioPlayer play];
}
- (void) stopBackgroundMusic {
[_audioPlayer pause];
}
In my MyScene.m file when I click a switch I have off I run:
[vc stopBackgroundMusic];
and I also have:
ViewController *vc;
declared above with viewcontroller.h imported.
This doesn't work. It plays fine but I just can't stop it. It seems easy to accomplish but maybe I'm missing something.
AVAudioPlayer successfully calls play method and is working properly in the simulator but it is not playing sound. The device has iOS 7.1.1. This is the code that I have used.
NSBundle *mainBundle = [NSBundle mainBundle];
NSString *filePath = [mainBundle pathForResource:#"miata-hn" ofType:#"wav"];
NSData *fileData = [NSData dataWithContentsOfFile:filePath];
NSError *error = nil;
/* Start the audio player */
self.playerAudio = [[AVAudioPlayer alloc] initWithData:fileData error:&error];
self.playerAudio.volume = 1;
if (error)
{
NSLog(#"error localized description %#",[error localizedDescription]);
}
if (self.playerAudio != nil)
{
/* Set the delegate and start playing */
self.playerAudio.delegate = self;
if ([self.playerAudio prepareToPlay] && [self.playerAudio play])
{
NSLog(#"player success");
}
else
{
NSLog(#"sound player failed to play audio");
}
}
else
{
/* Failed to instantiate AVAudioPlayer */
}
I got The solution. After adding this line of code the audio is audible in app.
AVAudioSession should be activated.
**
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayback error:&error];
[[AVAudioSession sharedInstance] setActive:YES error:&error];
**
Try using:
NSURL *fileURL = [[NSURL alloc] initFileURLWithPath:soundFilePath];
AVAudioPlayer *newPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:fileURL error:nil];
For some reason, the cleanupPlayer method is a little buggy and isn't releasing the audio player correctly. My application crashes from time to time, and I suspect it's due to a memory issue. Also, when I try to play an audio file twice (on button click), the second time the audio sometimes cuts out. I'm a bit of a newbie, so any help would be greatly appreciated!
Here is a snippet of code:
.h file:
#property (retain,nonatomic)AVAudioPlayer *player;
.m file:
-(void)playSound:(NSString *)fileName
{
// Play
NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:fileName ofType:kSoundFileType]];
_player = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:nil];
_player.delegate = self;
[_player prepareToPlay];
[_player play];
}
- (void)audioPlayerDidFinishPlaying:(AVAudioPlayer *)player successfully:(BOOL)flag
{
[self cleanupPlayer];
}
-(void)cleanupPlayer
{
if(_player != nil) {
[_player release];
}
try this...
-(void)playSound:(NSString *)fileName
{
if (_player.isPlaying) {
[_player stop];
}
NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:fileName ofType:#"mp3"]];
_player = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:nil];
_player.delegate = self;
[_player prepareToPlay];
[_player play];
}
- (void)audioPlayerDidFinishPlaying:(AVAudioPlayer *)player successfully:(BOOL)flag
{
[self cleanupPlayer];
}
-(void)cleanupPlayer
{
_player =nil;
}
I'm trying to play remote .mp3 file
but its giving the following error.
The operation couldn’t be completed. (OSStatus error -43.)
here is my code :
- (void)viewDidLoad
{
[super viewDidLoad];
isPlaying = NO;
/*
NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle]
pathForResource:#"Dar-e-Nabi-Per" ofType:#"mp3"]];
*/
NSURL *url = [NSURL
URLWithString:#"http://megdadhashem.wapego.ru/files/56727/tubidy_mp3_e2afc5.mp3"];
NSError *error;
audioPlayer = [[AVAudioPlayer alloc]
initWithContentsOfURL:url
error:&error];
if (error)
{
NSLog(#"Error in audioPlayer: %#",
[error localizedDescription]);
}
else
{
audioPlayer.delegate = self;
[audioPlayer prepareToPlay];
}
}
Can anyone please guide me where i'm doing mistake
For steaming audio from a remote server, use AVPlayer instead of AVAudioPLayer.
AVPlayer Documentation
Sample Code:
- (void)playSampleSong:(NSString *)iSongName {
NSString *aSongURL = [NSString stringWithFormat:#"http://megdadhashem.wapego.ru/files/56727/tubidy_mp3_e2afc5.mp3"];
// NSLog(#"Song URL : %#", aSongURL);
AVPlayerItem *aPlayerItem = [[AVPlayerItem alloc] initWithURL:[NSURL URLWithString:aSongURL]];
AVPlayer *anAudioStreamer = [[AVPlayer alloc] initWithPlayerItem:aPlayerItem];
[anAudioStreamer play];
// Access Current Time
NSTimeInterval aCurrentTime = CMTimeGetSeconds(anAudioStreamer.currentTime);
// Access Duration
NSTimeInterval aDuration = CMTimeGetSeconds(anAudioStreamer.currentItem.asset.duration);
}
Use this to play song from URL
NSData *songData=[NSData dataWithContentsOfURL:url];
self.player = [[AVAudioPlayer alloc] initWithData:songData error:nil];
self.player.numberOfLoops=0;
_player.delegate=self;
[_player prepareToPlay];
[_player play]
