保存多个录音音频文件并获取所有录音音频

我正在使用AVAudiofoundation进行音频录制，音频正在正确存储和播放，但是我的问题是我必须录制多个音频，并且我必须在表中显示它，现在我只得到一个URL地址。请帮助我找到解决方案。

此按钮显示为暂停录音，我想在这里我想为我的问题做些事情

    - (IBAction)recordPauseTapped:(id)sender
    {
        // Stop the audio player before recording
        if (player.playing)
        {
            [player stop];
        }

        if (!recorder.recording)
        {
            AVAudioSession *session = [AVAudioSession sharedInstance];
            [session setActive:YES error:nil];
            // Start recording
            [recorder record];
            [recordPauseButton setTitle:@"Pause" forState:UIControlStateNormal];
        }
        else
        {
            // Pause recording
            [recorder pause];
            [recordPauseButton setTitle:@"Record" forState:UIControlStateNormal];
        }

        [stopButton setEnabled:YES];
        [playButton setEnabled:NO];
    }

此按钮用于停止录制

    - (IBAction)stopTapped:(id)sender
    {
        [recorder stop];
        AVAudioSession *audioSession = [AVAudioSession sharedInstance];
        [audioSession setActive:NO error:nil];
        NSString *urr=[recorder.url absoluteString];
        [recordeddata addObject:urr];

    }

此按钮用于播放录制的音频

    - (IBAction)playTapped:(id)sender {
        if (!recorder.recording)
        {
             player = [[AVAudioPlayer alloc] initWithContentsOfURL:recorder.url error:nil];
            [player setDelegate:self];
            [player play];
            [_tableview reloadData];
        }
    }

您仅使用一个文件路径来初始化录音机，因此一次只能保存一个音频

NSMutableArray *pathComponents = [NSMutableArray arrayWithObjects:
                           [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject],
                           @"MyAudioMemo.m4a",
                           nil];

使这个名字MyAudioMemo.m4a充满活力，

当您想录制新音频时

- (int)numberOfFilesInDocPath
{
    NSString *docPath = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents"];
    NSFileManager *filemgr = [NSFileManager defaultManager];
    NSArray *filelist= [filemgr directoryContentsAtPath: docPath];
    int count = [filelist count];
    return count;
}
- (void)recordNewAudioWithFileName
{
    int numberOfFiles = [self numberOfFilesInDocPath];
    NSString *newFileName = [NSString stringWithFormat:@"MyAudioMemo_%d.m4a",numberOfFiles];
    NSMutableArray *pathComponents = [NSMutableArray arrayWithObjects:
                                      [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject],
                                  newFileName,
                                  nil];
     NSURL *outputFileURL = [NSURL fileURLWithPathComponents:pathComponents];


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

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

    [recordSetting setValue:[NSNumber numberWithInt:kAudioFormatMPEG4AAC] forKey:AVFormatIDKey];
    [recordSetting setValue:[NSNumber numberWithFloat:44100.0] forKey:AVSampleRateKey];
    [recordSetting setValue:[NSNumber numberWithInt: 2] forKey:AVNumberOfChannelsKey];

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


}

对于整个实施，请检查此

希望这可以帮助，
