How to re save (copy) audio file in document directory and send that re saved audio file?

I'm working on record audio file and send to server. Record, stop, play and sending working properly. But my problem is if i click stop button i want to re save that audio file with new name in docs dir and send this audio file to server. My code is...

// File path where the recording will be saved on the iOS device
audioFilePath = [[self applicationDocumentsDirectory].path stringByAppendingPathComponent:@"RecordAudio.wav"];
NSLog(@"%@", audioFilePath);

NSURL *outputFileURL = [NSURL fileURLWithPath:audioFilePath];

// Setup audio session
AVAudioSession *session = [AVAudioSession sharedInstance];
[session setCategory:AVAudioSessionCategoryRecord error:nil];

// Define the recorder setting
NSMutableDictionary *recordSetting = [[NSMutableDictionary alloc] init];

[recordSetting setValue:[NSNumber numberWithInt:kAudioFormatLinearPCM] forKey:AVFormatIDKey];
[recordSetting setValue:[NSNumber numberWithFloat:44100.0] forKey:AVSampleRateKey];
[recordSetting setValue:[NSNumber numberWithInt: 2] forKey:AVNumberOfChannelsKey];
[recordSetting setValue:[NSNumber numberWithInt: 16] forKey:AVLinearPCMBitDepthKey];
[recordSetting setValue:[NSNumber numberWithBool: NO] forKey:AVLinearPCMIsBigEndianKey];
[recordSetting setValue:[NSNumber numberWithBool: NO] forKey:AVLinearPCMIsFloatKey];
[recordSetting setValue:[NSNumber numberWithInt: AVAudioQualityHigh] forKey:AVEncoderAudioQualityKey];

// Initiate and prepare the recorder
NSError *error = nil;
audioRecorder = [[AVAudioRecorder alloc] initWithURL:outputFileURL settings:recordSetting error:&error];
audioRecorder.delegate = self;
audioRecorder.meteringEnabled = YES;

// Deal with any errors
if (error)
NSLog(@"error: %@", [error localizedDescription]);
else
[audioRecorder prepareToRecord];

// Check to see if we have permission to use the microphone.
if ([session respondsToSelector:@selector(requestRecordPermission:)]) {
    [session performSelector:@selector(requestRecordPermission:) withObject:^(BOOL granted) {
        if (granted) {
            NSLog(@"Mic access granted");
        }
        else {
            NSLog(@"Mic access NOT granted");
        }
    }];
}

-(NSURL *)applicationDocumentsDirectory {

NSLog(@"%@", [[[NSFileManager defaultManager] URLsForDirectory:NSDocumentDirectory
                                                     inDomains:NSUserDomainMask] lastObject]);
return [[[NSFileManager defaultManager] URLsForDirectory:NSDocumentDirectory
                                               inDomains:NSUserDomainMask] lastObject];
}

- (IBAction)record:(id)sender {

NSLog(@"Started Recording");
if (!audioRecorder.recording)
{
    AVAudioSession *session = [AVAudioSession sharedInstance];
    [session setCategory:AVAudioSessionCategoryRecord error:nil];
    [session setActive:YES error:nil];

    // Start recording
    [audioRecorder record];
}
}

- (IBAction)stop:(id)sender {

NSLog(@"Stop Recording");
if ([audioRecorder isRecording])
{
    [audioRecorder stop];
    AVAudioSession *audioSession = [AVAudioSession sharedInstance];
    [audioSession setCategory:AVAudioSessionCategoryPlayback error:nil];
    [audioSession setActive:NO error:nil];

}
else if (audioPlayer.playing)
[audioPlayer stop];
}

If i write this code in stop method ..

NSLog(@"%@", audioRecorder.url); // RecordAudio.wav
NSString *urlString = [audioRecorder.url.absoluteString stringByReplacingOccurrencesOfString:@"RecordAudio.wav" withString:@"RecordAudio2.wav"];
self.sendingURL = [NSURL URLWithString:urlString];
NSLog(@"%@", self.sendingURL);

When i click stop button i'm getting error Error: The operation couldn’t be completed. (OSStatus error 2003334207.)

You cannot change the name of that audio file. What you can do is create a copy of that audio file with your new name using the NSFileManager class

 NSFileManager *fManager = [NSFileManager defaultManager];
    [fManager copyItemAtURL:oldURL toURL:newURL error:error];
