I am using AV audio framework to record audio files on the iPhone. Here is the current code :
NSArray *dirPaths;
NSString *docsDir;
dirPaths = NSSearchPathForDirectoriesInDomains(
NSDocumentDirectory, NSUserDomainMask, YES);
docsDir = [dirPaths objectAtIndex:0];
NSString *soundFilePath = [docsDir
stringByAppendingPathComponent:@"sound.caf"];
NSURL *soundFileURL = [NSURL fileURLWithPath:soundFilePath];
NSDictionary *recordSettings = [NSDictionary
dictionaryWithObjectsAndKeys:
[NSNumber numberWithInt:AVAudioQualityMin],
AVEncoderAudioQualityKey,
[NSNumber numberWithInt:16],
AVEncoderBitRateKey,
[NSNumber numberWithInt: 2],
AVNumberOfChannelsKey,
[NSNumber numberWithFloat:44100.0],
AVSampleRateKey,
nil];
NSError *error = nil;
audioRecorder = [[AVAudioRecorder alloc]
initWithURL:soundFileURL
settings:recordSettings
error:&error];
Now I have another function and I want to send the sound.caf file to that function something like:
NSData *soundData = [NSData dataWithContentsOfFile:[[NSBundle mainBundle] pathForResource:soundFilePath ofType:@"caf"]];
But for some reason that above line seems to return a 0kb file.
Any suggestions?

In your code, file URL is not global. You try the code given
First of all you have to start a new audio session:
-(void) initAudioSession {
AVAudioSession * audioSession = [AVAudioSession sharedInstance];
[audioSession setCategory:AVAudioSessionCategoryPlayAndRecord error: &error];
[audioSession setActive:YES error: &error];
}
-(void) recordStart {
NSArray *dirPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *docsDir = [dirPaths objectAtIndex:0];
tempFilePath = [NSURL fileURLWithPath:[docsDir stringByAppendingPathComponent:[NSString stringWithFormat: @"%@.%@",audioFileName, @"caf"]]];
NSMutableDictionary* recordSetting = [[NSMutableDictionary alloc] init];
[recordSetting setValue :[NSNumber numberWithInt:kAudioFormatAppleIMA4] forKey:AVFormatIDKey];
[recordSetting setValue:[NSNumber numberWithFloat:44100.0] forKey:AVSampleRateKey];
[recordSetting setValue:[NSNumber numberWithInt: 2] forKey:AVNumberOfChannelsKey];
stringByAppendingPathComponent: [NSString stringWithFormat: @"%@.%@",audioFileName, @"caf"]]];
recorder = [[ AVAudioRecorder alloc] initWithURL:tempFilePath settings:recordSetting error:&error];
[recorder setDelegate:self];
[recorder prepareToRecord];
[recorder record];
}
-(void) stopRecording{
[recorder stop];
}
-(void) playRecord{
avPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:tempFilePath error:&error];
[avPlayer prepareToPlay];
[avPlayer play];
}

I don't see you triggering the record method: http://developer.apple.com/library/ios/#documentation/AVFoundation/Reference/AVAudioRecorder_ClassReference/Reference/Reference.html
Nor points your file open to the same file name.
Last, you cant save in the app directory. You can only save data in the Documents folder.
