Question

我有使用以下代码的第三方项目此代码不是全部，但它在应用程序包中写入大文件（比如记录）如何找到该文件？

NSError *audioSessionError = nil;
    AVAudioSession *audioSession= [AVAudioSession sharedInstance];
    [audioSession setCategory:AVAudioSessionCategoryPlayAndRecord error:&audioSessionError];
    [audioSession setMode:AVAudioSessionModeDefault error:&audioSessionError];
    [audioSession setPreferredSampleRate:16000.0f error:&audioSessionError];
    [audioSession setPreferredInputNumberOfChannels:1 error:&audioSessionError];
    [audioSession setActive:TRUE error:&audioSessionError];
    _sampleRate= [audioSession sampleRate];

    // make a capture session that uses the audio session
    _captureSession = [[AVCaptureSession alloc]init];
    _captureSession.sessionPreset = AVCaptureSessionPreset640x480;
    _captureSession.automaticallyConfiguresApplicationAudioSession= NO;




 _startTimeMS = [[NSDate date] timeIntervalSince1970] * 1000;

    dispatch_queue_t videoQueue = dispatch_queue_create("smmaProcessingQueueVideo", NULL);
    [_videoOutput setSampleBufferDelegate:self queue:videoQueue];

    dispatch_queue_t audioQueue = dispatch_queue_create("smmaProcessingQueueAudio", NULL);
    [_audioOutput setSampleBufferDelegate:self queue:audioQueue];

相同的视频代码，现在，此代码在应用程序中写入太大的文件（最多2 GB）。音频+视频，

我想找到＆amp;删除该文件。我试过

NSString *appFolderPath = [[NSBundle mainBundle] resourcePath];
NSFileManager *fileManager = [NSFileManager defaultManager];
NSLog(@"App Directory is: %@", appFolderPath);
NSLog(@"Directory Contents:\n%@", [fileManager directoryContentsAtPath: appFolderPath]);

怎么做？任何帮助都会非常感激。

您可以清除temp directory，

  NSArray* tmpDirectory = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:NSTemporaryDirectory() error:NULL];
for (NSString *file in tmpDirectory) {


    BOOL suc = [[NSFileManager defaultManager] removeItemAtPath:[NSString stringWithFormat:@"%@%@", NSTemporaryDirectory(), file] error:NULL];

    if (suc) {

        NSLog(@"done");
    }
    NSLog(@"file : %@%@",NSTemporaryDirectory(), file);
}

您可以清除cachedirectory喜欢，

         dirPaths = NSSearchPathForDirectoriesInDomains(
                                                   NSCachesDirectory, NSUserDomainMask, YES);
    docsDir = [dirPaths objectAtIndex:0];


    NSFileManager *manager1 = [NSFileManager defaultManager];

    NSArray *filesArDirectory1 = [manager contentsOfDirectoryAtPath:docsDir error:nil];

    NSError *err1;

    for (NSString *file2 in filesArDirectory1) {

        BOOL success = [manager1 removeItemAtPath:[NSString stringWithFormat:@"%@%@", docsDir,file2] error:&err1];

        if (!success || err1) {
            NSLog(@"error description : %@",[err1 localizedDescription]);
            NSLog(@"failed2");

        }
        else{
            NSLog(@"Success2");
        }
        NSLog(@"files : %@",file2);

    }

如果存储数据，请尝试清除此目录。检查您的文档目录是否存储了大数据，然后您还需要对其进行管理。

希望这会有所帮助：）
