I am using AVFoundation to play wav files. But i could not make it play. Also no errors or warnings showed up.
XCode is 4.2 and device is iOS 5.
- (IBAction) playSelectedAlarm:(id)sender {
UIButton *button = (UIButton *)sender;
int bTag = button.tag;
NSString *fileName = [NSString stringWithFormat:#"%d23333", bTag];
NSLog(#"%#", fileName);
NSString *path = [[NSBundle mainBundle] pathForResource:fileName ofType:#"wav"];
NSURL *fileURL = [[NSURL alloc] initFileURLWithPath: path];
AVAudioPlayer *theAudio=[[AVAudioPlayer alloc] initWithContentsOfURL:fileURL error:NULL];
theAudio.volume = 1.0;
theAudio.delegate = self;
[theAudio prepareToPlay];
[theAudio play];
}
Here is the solution;
I set AVAudioPlayer in header file..
#property (nonatomic, retain) AVAudioPlayer *theAudio;
i guess 'retain' is solved my problem. Because after i sending "play", it sends "release" to balance the alloc. When AVAudioPlayer is deallocated it stops playing audio.
I have had the same issue with Xcode 4.5. Making the AVAudioPlayer into a strongly typed property made it play.
So the following code needs added to the #interface:
#property (nonatomic, strong) AVAudioPlayer *theAudio;
The #implementation would then become:
- (IBAction) playSelectedAlarm:(id)sender {
UIButton *button = (UIButton *)sender;
int bTag = button.tag;
NSString *fileName = [NSString stringWithFormat:#"%d23333", bTag];
NSLog(#"%#", fileName);
NSString *path = [[NSBundle mainBundle] pathForResource:fileName ofType:#"wav"];
NSURL *fileURL = [[NSURL alloc] initFileURLWithPath: path];
self.theAudio=[[AVAudioPlayer alloc] initWithContentsOfURL:fileURL error:NULL];
self.theAudio.volume = 1.0;
self.theAudio.delegate = self;
[self.theAudio prepareToPlay];
[self.theAudio play];
}

I am trying to play a sound when I click a button, the sound clip is 10 sec, the application runs fine and when I click the button nothing happens there are no errors or nothing, this is my code
.m file
#import "ViewController.h"
#import <AVFoundation/AVFoundation.h>
- (IBAction)Play:(id)sender {
AVAudioPlayer *audioPlayer;
NSString *audioPath = [[NSBundle mainBundle]pathForResource:#"Blesgaes" ofType:#"mp3"];
NSURL *audioURL =[NSURL fileURLWithPath:audioPath];
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:audioURL error:nil];
[audioPlayer play];
}
.h file
#import <AVFoundation/AVFoundation.h>
#interface ViewController : UIViewController
- (IBAction)Play:(id)sender;
I have added AVFoundation framework and I have followed these steps

http://code-and-coffee.blogspot.in/2012/09/how-to-play-audio-in-ios.html
Any ideas what I am doing wrong.
Below is the simple code:-
- (IBAction)playAudio:(id)sender {
AVAudioPlayer *audioPlayer;
NSString *audioPath = [[NSBundle
mainBundle] pathForResource:#"Woof"
ofType:#"mp3"];
NSURL *audioURL = [NSURL
fileURLWithPath:audioPath];
NSError *audioError = [[NSError alloc] init];
audioPlayer = [[AVAudioPlayer alloc]
initWithContentsOfURL:audioURL
error:&audioError];
if (!audioError) {
[audioPlayer play];
NSLog(#"Woof!");
}
else {
NSLog(#"Error!");
}
}
I'm following in a tutorial on how to play mp3 sounds when pressing a button.
I created a button (playSound).
I added it to the view controller interface:
- (IBACTION)playSound:(id)sender;
in the implementation I declared the needed header files and I wrote the following:
#import "AudioToolbox/AudioToolbox.h"
#import "AVFoundation/AVfoundation.h"
- (IBAction)playSound:(id)sender {
//NSLog(#"this button works");
AVAudioPlayer *audioPlayer;
NSString *audioPath = [[NSBundle mainBundle] pathForResource:#"audio" ofType:#"mp3"];
//NSLog(#"%#", audioPath);
NSURL *audioURL = [NSURL fileURLWithPath:audioPath];
//NSLog(#"%#", audioURL);
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:audioURL error:nil];
[audioPlayer play];
}
I'm not getting any errors. the NSlogs are logging the URL fine, and now I have no clue where to look further. I also checked if my MP3 sound was maybe damaged, but that was also not the case. all i hear is a little crackling noise for 1 second. then it stops.
You declared a local variable audioPlayer to hold a pointer to the player. As soon as your button handler returns the player is being released before it has a chance to play your sound file. Declare a property and use it instead of the local variable.
In YourViewController.m file
#interface YourViewController ()
#property (nonatomic, strong) AVAudioPlayer *audioPlayer;
#end
or in YourViewController.h file
#interface YourViewController : UIViewController
#property (nonatomic, strong) AVAudioPlayer *audioPlayer;
#end
Then replace audioPlayer with self.audioPlayer in your code.
try this its working for me
in .h
AVAudioPlayer * _backgroundMusicPlayer;
in .m
NSString *backgroundMusicPath = [[NSBundle mainBundle] pathForResource:#"Theme" ofType:#"mp3"];
NSURL *backgroundMusicURL = [NSURL fileURLWithPath:backgroundMusicPath];
NSError *error;
_backgroundMusicPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:backgroundMusicURL error:&error];
[_backgroundMusicPlayer setDelegate:self]; // We need this so we can restart after interruptions
[_backgroundMusicPlayer setNumberOfLoops:-1];
[_backgroundMusicPlayer play];
Edited
NSString *soundFilePath = [[NSBundle mainBundle] pathForResource:#"Name of your audio file"
ofType:#"type of your audio file example: mp3"];
NSURL *soundFileURL = [NSURL fileURLWithPath:soundFilePath];
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:soundFileURL error:nil];
audioPlayer.numberOfLoops = -1;
audioPlayer.delegate=self;
[audioPlayer play];
Try this and let me know. Make sure you set the delegate for audioPlayer.
Firstly re add your music file in your project , then try this code
With the log you can see error.
NSError *error;
NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:#"bg_sound" ofType:#"mp3"]];
AVAudioPlayer *audioPlayer = [[AVAudioPlayer alloc]
initWithContentsOfURL:url
error:&error];
if (error){
//Print Error
NSLog(#"Error in audioPlayer: %#",
[error localizedDescription]);
} else {
audioPlayer.delegate = self;
[audioPlayer prepareToPlay];
[audioPlayer setNumberOfLoops: -1];
[audioPlayer play];
audioPlayer.volume=1.0;
}
Make sure your music files are properly added in project
Its simple: My video player shows up, but never plays anything. The file I am trying to play exist already (checked).
I am just starting with a new "Single View" project.
#import "ViewController.h"
#import <MediaPlayer/MediaPlayer.h>
#interface ViewController ()
#property (nonatomic, strong) MPMoviePlayerController *player;
#end
#implementation ViewController
- (void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];
NSString *documentsDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString *filepath = [NSString stringWithFormat:#"%#/Videos/fileSequence0.ts", documentsDirectory];
NSLog(#"!! %i", [[NSFileManager defaultManager] fileExistsAtPath:filepath]);
NSURL *fileURL = [NSURL fileURLWithPath:filepath];
_player = [[MPMoviePlayerController alloc] initWithContentURL:fileURL];
[_player.view setFrame: CGRectMake(0, 0, 500, 500)];
[self.view addSubview:_player.view];
[_player play];
}
#end
Use below written code just before executing play statement.
_player.numberOfLoops=0;
_player.delegate=self;
[_player prepareToPlay];
.ts extension not works with ios. try some other extension videos ie. .mp4 . if problem arises then try to use [_player prepareToPlay];
try this one- Convert your url into NSdata
NSString* resourcePath = self.audioStr; //your video file formet should be .mp4
NSData *_objectData = [NSData dataWithContentsOfURL:[NSURL URLWithString:resourcePath]];
NSError *error = [[NSError alloc] init];
NSLog(#"url is %#",resourcePath);
_player = [[MPMoviePlayerController alloc] initWithData:_objectData error:&error];
[_player.view setFrame: CGRectMake(0, 0, 500, 500)];
[_player prepareToPlay];
_player.controlStyle = MPMovieControlStyleFullscreen;
_player.shouldAutoplay = NO;
[_player setFullscreen:YES animated:YES];
[self.view addSubview:_player.view];
[_player play];
hope it will help u
After updating to xCode 4.6 my audio player crashes with no error logs. I cannot log the error as it crashes on play. I get no message on the debugger only a thread/ breakpoint on play.Anyone any ideas?
NSError *error;
NSString *stringPath1 = [[NSBundle mainBundle] pathForResource:#"beep" ofType:#"mp3"];
NSURL *url1 = [NSURL fileURLWithPath:stringPath1];
playerForRecording = [[AVAudioPlayer alloc] initWithContentsOfURL:url1 error:&error];
[playerForRecording setDelegate:self];
[playerForRecording play];
http://i1107.photobucket.com/albums/h385/snksnk1/stack%20overflow/ScreenShot2013-02-05at54421PM_zps72842a8f.png
I'm using the same compiler and this works for me:
NSError *error;
NSString *stringPath1 = [[NSBundle mainBundle] pathForResource:#"beep" ofType:#"mp3"];
NSURL *url1 = [NSURL fileURLWithPath:stringPath1];
NSAssert(url1, #"URL is valid.");
self.player = [[AVAudioPlayer alloc] initWithContentsOfURL:url1 error:&error];
if(!self.player)
{
NSLog(#"Error creating player: %#", error);
}
[self.player play];
Of course, in the .h, are the lines:
#import <AVFoundation/AVFoundation.h>
#interface myProgramViewController : UIViewController<AVAudioPlayerDelegate>
...
#property (nonatomic, strong) AVAudioPlayer* player;
with, in the .m, the corresponding:
#synthesize player = mPlayer;
Hope this helps.
I want to play a sound when a button is pressed. I tried this:
-(void)PlayClick
{
NSURL* musicFile = [NSURL fileURLWithPath:[[NSBundle mainBundle]
pathForResource:#"BubblePopv4"
ofType:#"mp3"]];
AVAudioPlayer *click = [[AVAudioPlayer alloc] initWithContentsOfURL:musicFile error:nil];
[click play];
}
…and imported #import <AudioToolbox/AudioToolbox.h> and #import <AVFoundation/AVFoundation.h>
but for some reason the sound is not playing. The name and type are right because the file I added to the project is "BubblePopv4.mp3". The volume on the iPad is on maximum, and the sound plays fine on iTunes! Any ideas?
Leave it, Don't do it in a new Class, simple stuff for you:
- (void)playSoundWithOfThisFile:(NSString*)fileNameWithExtension {
// Eg - abc.mp3
AVAudioPlayer *audioPlayerObj;
NSString *filePath;
filePath= [[NSString stringWithFormat:#"%#", [[NSBundle mainBundle] resourcePath]] retain];
if(!audioPlayerObj)
audioPlayerObj = [AVAudioPlayer alloc];
NSURL *acutualFilePath= [NSURL fileURLWithPath:[NSString stringWithFormat:#"%#/%#",filePath,fileNameWithExtension]];
NSError *error;
[audioPlayerObj initWithContentsOfURL:acutualFilePath error:&error];
[audioPlayerObj play];
}
Do this:
In .h file:
Use this delegate - <AVAudioPlayerDelegate>
#import "AVFoundation/AVAudioPlayer.h"
AVAudioPlayer *audioPlayerObj;
NSString *filePath;
In .m file , In some method:
filePath= [[NSString stringWithFormat:#"%#", [[NSBundle mainBundle] resourcePath]] retain];
if(!audioPlayerObj)
audioPlayerObj = [AVAudioPlayer alloc];
And add these two methods:
- (id)initWithFileName:(NSString*)fileNameWithExtension {
if ((self = [super init])) {
NSURL *acutualFilePath= [NSURL fileURLWithPath:[NSString stringWithFormat:#"%#/%#",filePath,fileNameWithExtension]];
NSError *error;
[audioPlayerObj initWithContentsOfURL:acutualFilePath error:&error];
}
return self;
}
- (void)playSound {
[audioPlayerObj play];
}
You can pass the filename to this Method - initWithFileName
and then call playSound method to play sound for you.
Hope this helps.
Replace url initialization with:
NSURL* musicFile = [NSURL initFileURLWithPath:[[NSBundle mainBundle]
pathForResource:#"BubblePopv4"
ofType:#"mp3"]];
