没有这样的文件或目录 iOS

Question

我正在尝试通过文件的路径获取文件的大小。这些文件是从我的应用程序中保存的视频。我使用下面的代码返回错误，说没有文件或目录。

NSString *urlPath = [self.localPathArray objectAtIndex:indexPath.row];
NSError *err;
NSDictionary * properties = [[NSFileManager defaultManager] attributesOfItemAtPath:urlPath error:&err];

这是下载文件后保存文件路径的方式

 - (void)URLSession:(NSURLSession *)session assetDownloadTask:
(AVAssetDownloadTask *)assetDownloadTask didFinishDownloadingToURL:(NSURL *)location {


        NSString *localPath = location.relativePath;
        NSLog(@"localPath: %@", localPath);

       [[NSUserDefaults standardUserDefaults]setValue:self.localPathArray forKey:@"AssetPath"];
    }

请参阅下面的错误屏幕截图和我的应用程序存储详细信息屏幕截图

Answer 1

The path with reference to root directory is called absolute. The path with reference to current directory is called relative

所以尝试

 NSString *localPath = location.path;

而不是

  NSString *localPath = location.relativePath;

例如

  - (void)URLSession:(NSURLSession *)session assetDownloadTask:
(AVAssetDownloadTask *)assetDownloadTask didFinishDownloadingToURL:(NSURL *)location {


        NSString *localPath = location.path;
        NSLog(@"localPath: %@", localPath);
        [self.localPathArray addObject: localPath];
       [[NSUserDefaults standardUserDefaults]setValue:self.localPathArray forKey:@"AssetPath"];
    }
