我们如何检查dropbox v2中的文件或文件夹

Question

我在dropbox api v2中检查主路径中的文件或文件夹 我正在尝试这种方法

我在obj c中的代码

DBUserClient *client = [DBClientsManager authorizedClient];

//NSString *searchPath = @"";
// "Full Dropbox" or "/Apps/<APP_NAME>/" if app has permission "App Folder").
[[client.filesRoutes listFolder:path]
 setResponseBlock:^(DBFILESListFolderResult *result, DBFILESListFolderError *routeError, DBRequestError *networkError) {
     if (result) {
         [self displayPhotos:result.entries];

     } else {

         NSString *title = @"";
         NSString *message = @"";
         if (routeError) {
             // Route-specific request error
             title = @"Route-specific error";
             if ([routeError isPath]) {
                 message = [NSString stringWithFormat:@"Invalid path: %@", routeError.path];
             }
         } else {
             // Generic request error
             title = @"Generic request error";
             if ([networkError isInternalServerError]) {
                 DBRequestInternalServerError *internalServerError = [networkError asInternalServerError];
                 message = [NSString stringWithFormat:@"%@", internalServerError];
             } else if ([networkError isBadInputError]) {
                 DBRequestBadInputError *badInputError = [networkError asBadInputError];
                 message = [NSString stringWithFormat:@"%@", badInputError];
             } else if ([networkError isAuthError]) {
                 DBRequestAuthError *authError = [networkError asAuthError];
                 message = [NSString stringWithFormat:@"%@", authError];
             } else if ([networkError isRateLimitError]) {
                 DBRequestRateLimitError *rateLimitError = [networkError asRateLimitError];
                 message = [NSString stringWithFormat:@"%@", rateLimitError];
             } else if ([networkError isHttpError]) {
                 DBRequestHttpError *genericHttpError = [networkError asHttpError];
                 message = [NSString stringWithFormat:@"%@", genericHttpError];
             } else if ([networkError isClientError]) {
                 DBRequestClientError *genericLocalError = [networkError asClientError];
                 message = [NSString stringWithFormat:@"%@", genericLocalError];
             }
         }

         UIAlertController *alertController =
         [UIAlertController alertControllerWithTitle:title
                                             message:message
                                      preferredStyle:(UIAlertControllerStyle)UIAlertControllerStyleAlert];
         [alertController addAction:[UIAlertAction actionWithTitle:@"OK"
                                                             style:(UIAlertActionStyle)UIAlertActionStyleCancel
                                                           handler:nil]];
         [self presentViewController:alertController animated:YES completion:nil];

         //[self setFinished];
     }
 }];

以上代码显示DBFILESListFolderResult中的结果，并保存到NSArray<DBFILESListFolderResult *> *arr 现在结果显示.tag =文件/文件夹但是无法获取变量请帮助我如何获取此标记并保存在变量中 现在我的结果是## Result ##
