Play Audio iOS Objective-C

audio, ios, objective-c, xcode

Solution

Maybe you should try using the `NSBundle` method `pathForResource:ofType:` method to create the path to the file.

The following code should successfully play an audio file. I have only used it with an `mp3`, but I imagine it should also work with `m4a`. If this code does not work, you could try changing the format of the audio file. For this code, the audio file is located in the main project directory.

/* Use this code to play an audio file */
NSString *soundFilePath = [[NSBundle mainBundle] pathForResource:@"test"  ofType:@"m4a"];
NSURL *soundFileURL = [NSURL fileURLWithPath:soundFilePath];

AVAudioPlayer *player = [[AVAudioPlayer alloc] initWithContentsOfURL:soundFileURL error:nil];
player.numberOfLoops = -1; //Infinite

[player play];

EDIT

Ok, so try this:

NSString *soundFilePath = [NSString stringWithFormat:@"%@/test.m4a",[[NSBundle mainBundle] resourcePath]];
NSURL *soundFileURL = [NSURL fileURLWithPath:soundFilePath];

AVAudioPlayer *player = [[AVAudioPlayer alloc] initWithContentsOfURL:soundFileURL error:nil];
player.numberOfLoops = -1; //Infinite

[player play];

Also, make sure you do the proper imports:

#import <AudioToolbox/AudioToolbox.h>
#import <AVFoundation/AVFoundation.h>

Problem

I'm trying to get an audio file playing in my iOS app. This is my current code ``` NSString *soundFilePath = [NSString stringWithFormat:@"%@/test.m4a", [[NSBundle mainBundle] resourcePath]]; NSLog(@"%@",soundFilePath); NSURL *fileURL = [[NSURL alloc] initFileURLWithPath: soundFilePath]; audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:fileURL error:nil]; [[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayback error:nil]; [[AVAudioSession sharedInstance] setActive: YES error: nil]; [[UIApplication sharedApplication] beginReceivingRemoteControlEvents]; [audioPlayer setVolume:1.0]; audioPlayer.delegate = self; [audioPlayer stop]; [audioPlayer setCurrentTime:0]; [audioPlayer play]; ``` I've being checking a bunch of other posts but they all generally do the same thing. I'm not getting an error, but I don't hear any audio playing on the simulator or device. This is the path I get for the audio file on the simulator ``` /Users/username/Library/Application Support/iPhone Simulator/5.1/Applications/long-numbered-thing/BookAdventure.app/test.m4a ``` Any help is appreciated!
