How to implement loadedFile method in API V2

Here is my code , how to convert this into API v2 compitable methods.

-(void)prepareForRecoverDB{
    if(![Utility isNetworkAvailable]) {
        [Utility showAlertViewWithTitle:@Error! Message:@Unable to connect to the host. Please check your network connection. CancelTitle:@OK];
        return;
    }
    
    [self showLoadingView];
    
    DBMetadata *mData = [self.arrOfBackupFiles objectAtIndex:self.indexPath_.row];
    AppDelegate_Shared *appDelegate = (AppDelegate_Shared *)[UIApplication sharedApplication].delegate;
    DBRestClient *aClient = [[DBRestClient alloc] initWithSession:[DBSession sharedSession]];
    aClient.delegate = self;
    
    NSString *strPath = [appDelegate dbPath];
    NSArray *arrPath = [strPath componentsSeparatedByString:@/];
    NSString *lastPath = [arrPath lastObject];
    if([lastPath isEqualToString:mData.filename]){
        self.restoredFileName = @RentTracker.sqlite;
        [aClient loadFile:mData.path intoPath:[appDelegate dbPath:self.restoredFileName]];
    }
    else{
        [aClient loadFile:mData.path intoPath:[appDelegate dbPath:mData.filename]];
        self.restoredFileName = mData.filename;
        
    }
}
 
- (void)restClient:(DBRestClient*)client loadedFile:(NSString*)localPath {
    [self hideLoadingView];
    [Utility showAlertViewWithTitle:@Restored! Message:@File Restored Sucessful! CancelTitle:@OK];
    [[DBSession sharedSession] unlinkAll];
    AppDelegate_Shared *app = (AppDelegate_Shared *)[UIApplication sharedApplication].delegate;
 
    NSFileManager *fm = [NSFileManager defaultManager];
    [fm removeItemAtPath:[app dbPath] error:nil];
    
    [[NSUserDefaults standardUserDefaults] setValue:self.restoredFileName forKey:kStoreName];
    [[NSUserDefaults standardUserDefaults] synchronize];
 
    app.managedObjectModel = nil;
    app.managedObjectContext = nil;
    app.persistentStoreCoordinator = nil;
    
    [self.navigationController popViewControllerAnimated:YES];
}

If you're using the API v2 Objective-C SDK (which is recommended), the equivalent of the loadFile method would be any of the download methods.

You can find a sample of calling those here:

https://github.com/dropbox/dropbox-sdk-obj-c#download-style-request

As well as in the example app:

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];

So i thought may be i had mistaken something during uploading the data. Below is the code for uploading the sqlite dataPath to dropbox.

DB Path-

Before adding time stamp

/var/mobile/Containers/Data/Application/6D7A6DDA-45D0-4509-99A5-E635891D9DB9/Documents/RentTracker.sqlite

After adding time stamp

/var/mobile/Containers/Data/Application/AA188B71-1995-42A1-AC39-64AFD024E42A/Documents/RentTracker_IOS_01_02_2017_10_46_58.sqlite

So,what i am doing is , converting the db file path into data format and passing this as an input data [parameter], while in uploadData [parameter], i sent only the file name . Please correct me , if i doing something wrong in code . HELP ME !

Thank You

(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.)

Hi Greg,

Thanks for your valuable reply. As you suggested me to upload the root file path. But i am still confused in uploading the data. so what should i put in uploadData:?? parameter and what should be in inputData?? parameter. Thank You.

[[[client.filesRoutes uploadData:@"???"
mode:mode
autorename:@(YES)
clientModified:nil
mute:@(NO)
inputData:???]
setResponseBlock:^(DBFILESFileMetadata *result, DBFILESUploadError *routeError, DBRequestError *networkError) {
if (result) {
NSLog(@"\n", result);
      } else {
NSLog(@"\n\n", routeError, networkError);
      }
    }] setProgressBlock:^(int64_t bytesUploaded, int64_t totalBytesUploaded, int64_t totalBytesExpectedToUploaded) {
NSLog(@"\n%lld\n%lld\n%lld\n", bytesUploaded, totalBytesUploaded, totalBytesExpectedToUploaded);
}];

The documentation for this method can be found here:

https://dropbox.github.io/dropbox-sdk-obj-c/api-docs/latest/Classes/DBFILESUserAuthRoutes.html#/c:objc(cs)DBFILESUserAuthRoutes(im)uploadData:mode:autorename:clientModified:mute:inputData:

From there, the first parameter (which is unnamed in the calling code) is the "path" parameter. That's the path in the Dropbox account where you want to put the file when uploading it. For example, you could supply "/RentTracker.sqlite".

The "inputData" parameter should be a NSData object containing the actual data you want to upload.
