Playing a simple Audio file in iOS - objective-c

Question

A very common question but I can't figure out what I'm doing wrong in playing a simple audio file in iOS 10 and 9. I have the following code:
#import <AudioToolbox/AudioToolbox.h>
#import <AVFoundation/AVFoundation.h>
NSString *soundFilePath = [NSString stringWithFormat:#"%#",[[NSBundle mainBundle] pathForResource:#"www/sounds/ringbacktone" ofType:#"mp3"]];
[self playTone:soundFilePath Loop:YES];
-(void) playTone:(NSString *) soundFilePath Loop:(BOOL) loop{
NSLog(#"Sound File Path: %#",soundFilePath);
NSFileManager *fileManager = [NSFileManager defaultManager];
if ([fileManager fileExistsAtPath:soundFilePath]){
NSURL *soundFileURL = [NSURL fileURLWithPath:soundFilePath];
NSError *error = nil;
AVAudioPlayer *player = [[AVAudioPlayer alloc] initWithContentsOfURL:soundFileURL error:&error];
if (error){
NSLog(#"Error creating the audio player: %#",error);
}else{
if (loop == YES)
player.numberOfLoops = -1; //Infinite
[player setVolume:1.0];
[player play];
}
}else{
NSLog(#"No sound will be played. The file doesn't exist.");
}
}
The output is
Sound File Path: /var/containers/Bundle/Application/E8CCA88C-B6AB-4C36-9426-EFBB94E1D509/myapp.app/www/sounds/myfile.mp3
The file exists so the sound should play. I've tried wav,m4a and mp3 files without success.
I'm using the function before calling pjsip library. Not sure if it plays a role.
Any thoughts? Is there any other way to debug it further?

Answer 1

check this solution it may work :
1.create property for ur audio player:
#property (strong, nonatomic) AVAudioPlayer *audioPlayer;
2.write delegate methods for player: AVAudioPlayerDelegate
3.implement this in ur action :
yourSoundArray=[NSArray arrayWithObjects:#"sound1",#"sound2",#"sound3",#"sound4",#"sound5",#"sound6", nil];//dont include formate type
NSString *audioPath = [[NSBundle mainBundle] pathForResource: [yourSoundArray objectAtIndex:indexPath.row] ofType:#"mp3"];
NSLog(#"%#",audioPath);
NSURL *audioURL = [NSURL fileURLWithPath:audioPath];
NSError *audioError = [[NSError alloc] init];
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:audioURL error:&audioError];
audioPlayer.delegate=self;
if (!audioError) {
NSLog(#"playing!");
audioPlayer play];
}
else {
NSLog(#"Error!");
}
check the audio player-delegate action
-(void)audioPlayerDidFinishPlaying:(AVAudioPlayer *)player successfully:(BOOL)flag
{ NSLog(#"%d",playing the audio);
}

The answer was a combination of these:
in .h file I had to inherit from AVAudioPlayerDelegate, i.e.
#import <AudioToolbox/AudioToolbox.h>
#import <AVFoundation/AVFoundation.h>
#interface scAudioManager : NSObject <AVAudioPlayerDelegate>{
#property (strong, nonatomic) AVAudioPlayer *player;
}
And then in .m file:
NSString *soundFilePath = [NSString stringWithFormat:#"%#",[[NSBundle mainBundle] pathForResource:#"www/sounds/ringbacktone" ofType:#"mp3"]];
[self playTone:soundFilePath Loop:YES];
-(void) playTone:(NSString *) soundFilePath Loop:(BOOL) loop{
NSLog(#"Sound File Path: %#",soundFilePath);
NSFileManager *fileManager = [NSFileManager defaultManager];
if ([fileManager fileExistsAtPath:soundFilePath]){
NSURL *soundFileURL = [NSURL fileURLWithPath:soundFilePath];
NSError *error = nil;
_player = [[AVAudioPlayer alloc] initWithContentsOfURL:soundFileURL error:&error];
if (error){
NSLog(#"Error creating the audio player: %#",error);
}else{
if (loop == YES)
_player.numberOfLoops = -1; //Infinite
_player.volume=[[AVAudioSession sharedInstance] outputVolume];
_player.delegate = self;
[_player prepareToPlay]
[_player play];
}
}else{
NSLog(#"No sound will be played. The file doesn't exist.");
}
}
