빈 파일 AVAudioRecorder

Question

로 음성을 녹음 한 후 나는 AVAudioRecorder과 음성을 녹음하려고 녹음 후 나는 0 바이트와 빈 파일을 가지고 시도가 재생할 때, 나는

WARNING: [0x38cb1000] 998: Failure to setup sound, err = -50 

내가 사용하려고이 경고를 m4a와 같은 형식 및 0 바이트 크기. 어떤 도움을 주셔서 감사합니다.

편집 :

- (void)initRecorderWithName:(NSString *)name { 

    self.recordName = [NSString stringWithFormat:@"%@.wav",name]; 

    NSArray *pathComponents = [NSArray arrayWithObjects: 
           [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject], 
           self.recordName, nil]; 

    NSURL *outputFileURL = [NSURL fileURLWithPathComponents:pathComponents]; 

    self.currentSession = [AVAudioSession sharedInstance]; 
    [self.currentSession setCategory:AVAudioSessionCategoryRecord error:nil]; 

    NSMutableDictionary *recordingSettings= [[NSMutableDictionary alloc] init]; 

    [recordingSettings setValue:[NSNumber numberWithInt:kAudioFormatLinearPCM] forKey:AVFormatIDKey]; 
    [recordingSettings setValue:[NSNumber numberWithFloat:44100.0] forKey:AVSampleRateKey]; 
    [recordingSettings setValue:[NSNumber numberWithInt: 2] forKey:AVNumberOfChannelsKey];

    recorder = [[AVAudioRecorder alloc] initWithURL:outputFileURL settings:recordingSettings error:NULL]; 
    recorder.delegate = self; 
    recorder.meteringEnabled = YES; 
    [recorder prepareToRecord]; 

} 

: 내가 여기에 오디오를 녹음 및 애니메이션

- (void)commanClickOnPetal:(FlowerObject *)flowerObject andButton:(UIButton *)sender { 

    if ([[NSUserDefaults standardUserDefaults] boolForKey:flowerObject.imageName] == NO || ![[NSUserDefaults standardUserDefaults] boolForKey:flowerObject.imageName]) { 

     [self.flowerObject changeRecordedState:YES andKey:flowerObject.imageName]; 

     self.view.userInteractionEnabled = NO; 
     [self playFirstSound]; 

     [self initRecorderWithName:[NSString stringWithFormat:@"%@sound", flowerObject.imageName]]; 

     dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, 10 * NSEC_PER_SEC); 
     dispatch_after(popTime, dispatch_get_main_queue(), ^(void){ 

      [self startRecording]; 
      [self.recordIdentifierLabel setHidden:NO]; 


      [UIView animateWithDuration:1.f 
           delay:0.f 
          options: UIViewAnimationOptionRepeat | UIViewAnimationCurveLinear | UIViewAnimationOptionAutoreverse 
         animations:^{ 
          [self.recordIdentifierLabel setAlpha:0.0f]; 
         } completion:nil]; 


      [UIView transitionWithView:sender duration:29.0f options:UIViewAnimationOptionTransitionCrossDissolve | UIViewAnimationOptionAllowAnimatedContent animations:^{ 

       [sender setBackgroundImage:[UIImage imageNamed:[NSString stringWithFormat:@"%@BW",flowerObject.imageName]] forState:UIControlStateNormal]; 


      } completion:^(BOOL finished) { 

       self.view.userInteractionEnabled = YES; 
       [self.recordIdentifierLabel setHidden:YES]; 

      }]; 

     }); 

    } else { 

     [self playSoundFromPetal:[NSString stringWithFormat:@"%@sound", flowerObject.imageName]]; 

    } 
} 

을 내 UI를 업데이트하려고 그리고 같은 시간에

레코더 초기화 내 방법입니다 녹음 후 MailCore를 사용하여 이메일로 소리를 보내지 만 파일은 0 바이트입니다. 녹음은 초 30를 계속하고 여기에 [자기 stopRecording]

- (void) startRecording { 

    if (!recorder.recording) { 
     AVAudioSession *session = self.currentSession; 
     [session setActive:YES error:nil]; 
     [recorder record]; 
     self.timer = [NSTimer scheduledTimerWithTimeInterval: 1.0 target:self selector:@selector(updateCountdown) userInfo:nil repeats: YES]; 
    } else { 
     [recorder stop]; 
    } 

} 

- (void) stopRecording { 

    [recorder stop]; 
    AVAudioSession *audioSession = [AVAudioSession sharedInstance]; 
    [audioSession setActive:NO error:nil]; 
    self.dictionaryWithRecords = (NSMutableDictionary *) @{@"URL": recorder.url, 
                  @"Name": self.recordName}; 

    dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{ 

     if ([[DBEmailSender sharedManager] emailAddress] != nil) { 

      [[DBEmailSender sharedManager] sendMailWithAddress:[[NSUserDefaults standardUserDefaults] objectForKey:@"email"] andCode:nil andFilePath:[self.dictionaryWithRecords objectForKey:@"Name"]]; 

     } 
    }); 
} 

- (void)updateCountdown { 

    self.tick += 1; 
    double seconds = fmod(self.tick, 60.0); 

    if (seconds == 29) { 
     self.tick = 0; 
     seconds = 0; 
     [self.timer invalidate]; 
     self.timer = nil; 
     [self stopRecording]; 
    } 

} 

그리고 메소드를 호출 한 후 내가 버튼을 클릭하여 내 소리를 재생한다 :

이

- (void)playSoundFromPetal:(NSString *)soundName { 

    SystemSoundID mySSID; 
    NSString *path = [NSTemporaryDirectory() stringByAppendingPathComponent:soundName]; 
    AudioServicesCreateSystemSoundID((__bridge CFURLRef)[NSURL fileURLWithPath: path], &mySSID); 
    AudioServicesPlaySystemSound(mySSID); 

}

그 뿐만 많은 이유가있을 수 있습니다 내 경우, 이미 AVAudioSession을 사용하여 오디오를 재생하는 또 다른 개체가있었습니다.
