How to implement loadedFile method in API V2

Hi, Greg 

   while  i am downloading the file path of  sqlite database , it's actually returing nil and  in error part it showing :-

DropboxHttpError[{
    ErrorContent = "path/not_found/..";
    RequestId = 9c2085907ba4e2bda71a08d96d62af8b;
    StatusCode = 409;
    UserMessage = nil;
}];

 This is  my code for downloading data  from sqlite data path -----

-(void)prepareForRecoverDataBase
{
    if(![Utility isNetworkAvailable]) {
        [Utility showAlertViewWithTitle:@"Error!" Message:@"Unable to connect to the host. Please check your network connection." CancelTitle:@"OK"];
        return;
    }
    
    [self showLoadingView];
   // NSString *filename = [self.arrOfBackupFiles objectAtIndex:self.indexPath_.row];
    DBFILESFileMetadata *fileMetadata= [self.arrOfBackupFiles objectAtIndex:self.indexPath_.row];
    AppDelegate_Shared *appDelegate = (AppDelegate_Shared *)[UIApplication sharedApplication].delegate;
    NSString *strPath = [appDelegate dbPath];
    NSArray *arrPath = [strPath componentsSeparatedByString:@"/"];
    NSString *lastPath = [arrPath lastObject];
    
    if([lastPath isEqualToString:fileMetadata.name]){
        self.restoredFileName = @"RentTracker.sqlite";
        [appDelegate dbPath:self.restoredFileName];
    }
    else
    {
        [appDelegate dbPath:fileMetadata.name];
        self.restoredFileName=fileMetadata.name;
    }
    NSLog(@"currentPath %@",[appDelegate dbPath:fileMetadata.name]);
    
    DBUserClient *client = [DBClientsManager authorizedClient];
    NSFileManager *fileManager = [NSFileManager defaultManager];
    NSURL *outputDirectory = [fileManager URLsForDirectory:NSDocumentDirectory inDomains:NSUserDomainMask][0];
    NSURL *outputUrl = [outputDirectory URLByAppendingPathComponent:fileMetadata.name];
    
    [[[client.filesRoutes downloadUrl:fileMetadata.pathDisplay overwrite:YES destination:outputUrl]
      setResponseBlock:^(DBFILESFileMetadata *result, DBFILESDownloadError *routeError, DBRequestError *networkError,
                         NSURL *destination) {
          if (result) {
              NSLog(@"%@\n", result);
              NSData *data = [[NSFileManager defaultManager] contentsAtPath:[destination path]];
              NSString *dataStr = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
              NSLog(@"%@\n", dataStr);
          } else {
              NSLog(@"%@\n%@\n", routeError, networkError);
          }
      }] setProgressBlock:^(int64_t bytesDownloaded, int64_t totalBytesDownloaded, int64_t totalBytesExpectedToDownload) {
          NSLog(@"%lld\n%lld\n%lld\n", bytesDownloaded, totalBytesDownloaded, totalBytesExpectedToDownload);
      }];
    
 
  //  [self downloadData:[appDelegate dbPath:fileMetadata.name]];
    [self hideLoadingView];
    [Utility showAlertViewWithTitle:@"Restored!" Message:@"File Restored Sucessful!" CancelTitle:@"OK"];
    //    NSFileManager *fm = [NSFileManager defaultManager];
    //    [fm removeItemAtPath:[appDelegate dbPath] error:nil];
    
    [[NSUserDefaults standardUserDefaults] setValue:self.restoredFileName forKey:kStoreName];
    [[NSUserDefaults standardUserDefaults] synchronize];
    
//    appDelegate.managedObjectModel = nil;
//    appDelegate.managedObjectContext = nil;
//    appDelegate.persistentStoreCoordinator = nil;
    
    [self.navigationController popViewControllerAnimated:YES];
}

(I was writing this in response to your new messages, but it looks like you either deleted them or there's an issue with the forum not displaying them.)

The 'path/not_found' error indicates that there's nothing at the path you specified. When referencing paths in Dropbox, you should use the remote path, not the local path of the file. For example, if you uploaded a file named "RentTracker.sqlite" to root, the path you would need to download it would just be "/RentTracker.sqlite". 

You can get the paths of uploaded files by listing the contents of folders using the listFolder methods. E.g., to list the root, supply the path as empty string "". (You can also manually check the contents of your own account on the Dropbox web site.) You should use the returned pathLower values to reference paths in other API calls.

Note that if your app has the "app folder" permission, all of these paths will automatically be relative to the app's app folder (by default inside "/Apps". Your app doesn't need to add that manually though.)
