Image Uploading with AFNetworking 3.0

Question

I am trying to upload images to server with AFNetworking 3.0.

Here is my code :

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
    [[manager POST:setUrl parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData>  _Nonnull formData)
    {
        //Current date with image name
        NSDateFormatter *dateFormatter=[[NSDateFormatter alloc] init];
        [dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss a"];
        [formData appendPartWithFileData:image name:namePara fileName:[NSString stringWithFormat:@"img_%@",[dateFormatter stringFromDate:[NSDate date]]] mimeType:@"image/png"];
        }progress:nil
        success:^(NSURLSessionDataTask * _Nonnull task, id  _Nonnull responseObject)
        {
            NSLog(@"%@",responseObject);
            [GMDCircleLoader hideFromView:self.view animated:YES];
            NSMutableDictionary *dir = [[NSMutableDictionary alloc]initWithDictionary:responseObject];
            if([dir valueForKey:@"error"])
            {
                UIAlertController *alert = [[singletone sharedManager]showAlert:NSLocalizedString(@"SIGNIN", nil) :[NSString stringWithFormat: @"%@",[dir valueForKey:@"error"]] ];
                [self.parentViewController presentViewController:alert animated:YES completion:nil];
            }
            else
            {
                //Successfull
                UIAlertController *alertController = [UIAlertController alertControllerWithTitle:NSLocalizedString(@"REGISTRATION", nil) message:[dir valueForKey:@"success"] preferredStyle:UIAlertControllerStyleAlert];
                UIAlertAction* ok = [UIAlertAction actionWithTitle:NSLocalizedString(@"OK", nil) style:UIAlertActionStyleCancel handler:^(UIAlertAction * action)
                {
                    [self.navigationController popViewControllerAnimated:YES];
                }];
            [alertController addAction:ok];
            [self presentViewController:alertController animated:YES completion:nil];
            }
            NSLog(@"response object : %@",responseObject);
        } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {                        NSLog(@"failure : %@",error.localizedDescription);
    }]resume];

It will get in success block with error : error In Image Uploading.
I have also tried from Postman to check my API response, but it's work fine from Postman. What is the problem with this code?

Can you please add a postman screenshot that does the API accepts file as base64 or simple file — gurmandeep, Aug 31 '16 at 09:35
sorry that i can't. but i can tell you the description of the all . that image that i have to send in postman is type of "File". and with other parameters like name,address..etc.. and the response i get is { "success": "Delivery registration done successfully" } — ios Developer, Aug 31 '16 at 09:43

Try below code and it working with AFNetworking 3.0 :

 AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];



    manager.responseSerializer = [AFJSONResponseSerializer serializerWithReadingOptions:NSJSONReadingAllowFragments];


    NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:BaseURL parameters:<parameter dictionary> constructingBodyWithBlock:^(id<AFMultipartFormData> formData)
                                    {

                                        if (profile_pic.length!=0) {

                                            [formData appendPartWithFileData:imageData name:@"profile_pic" fileName:@"ProfilePic" mimeType:@"image/jpeg"];
                                        }


                                    } error:nil];

    NSURLSessionUploadTask *uploadTask;
    uploadTask = [manager
                  uploadTaskWithStreamedRequest:request
                  progress:^(NSProgress * _Nonnull uploadProgress) {
                      // This is not called back on the main queue.
                      // You are responsible for dispatching to the main queue for UI updates

                  }
                  completionHandler:^(NSURLResponse * _Nonnull response, id  _Nullable responseObject, NSError * _Nullable error) {
                      if (error)
                      {


                      }
                      else
                      {

                      }
                  }];

    [uploadTask resume];

i got response Successful. but at server the image name not found as i send i.e. profilepic — ios Developer, Aug 31 '16 at 11:23
just confirm your parameter name (name:@"profile_pic") is correct — Ashwini Chougale, Aug 31 '16 at 11:34
ya i conform that parameter. but it strange that with my original parameter it's not working but with your parameter it's working. but not showing the image name at server. — ios Developer, Aug 31 '16 at 11:36

you try this

manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/plain"];

NSData *nsdataFromBase64String = [[NSData alloc] initWithBase64EncodedString:imageBytes options:0];
NSMutableDictionary *parameters = [NSMutableDictionary dictionary];   

AFHTTPSessionManager *manager = [[AFHTTPSessionManager alloc] initWithBaseURL:[NSURL URLWithString:stringURL]];// Your API

    [manager POST:stringURL parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData)
    {
        //do not put image inside parameters dictionary as I did, but append it!
        [formData appendPartWithFileData:nsdataFromBase64String name:fIds fileName:fileN mimeType:@"image/jpeg"];

    }
    success:^(NSURLSessionDataTask *task, id responseObject)
     {
         imgRes=@"success";
         //here is place for code executed in success case
     }
    failure:^(NSURLSessionDataTask *task, NSError *error)
    {
        imgRes=@"fail";
         //here is place for code executed in error case
     }];

Works perfectly at my end

This is what you are using in Postman

yes. you r ri8. i am using this way in postman – ios Developer Aug 31 '16 at 09:55
i am using send imagedata " NSData *dataToAppend = UIImageJPEGRepresentation(yourImage, 0.5)" is it the problem ? – ios Developer Aug 31 '16 at 09:57
Got this Printing description of responseObject: { success = "Delivery registration done successfully"; } – gurmandeep Aug 31 '16 at 10:26
post your code. by which you get successfull response . i just try – ios Developer Aug 31 '16 at 10:33
check for ToyotaSupra for tes1342@test.com – gurmandeep Aug 31 '16 at 10:50
How come we get success and you cannot see the image on server? – gurmandeep Sep 02 '16 at 03:23
with the @Ashwini code pass "name" value dummy you will get suceess mesge with no image but by passing right parameter in name value i.e. "user_photo" you will get error. – ios Developer Sep 02 '16 at 06:00

You need to set requestSerializer to @"multipart/form-data" for @"Content-Type".

AFHTTPSessionManager *manager = [[AFHTTPSessionManager alloc]initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
    manager.requestSerializer = [AFHTTPRequestSerializer serializer];


    manager.responseSerializer=[AFJSONResponseSerializer serializer];

    NSString *contentType = [NSString stringWithFormat:@"multipart/form-data"];
    [manager.requestSerializer setValue:contentType forHTTPHeaderField:@"Content-Type"];


    [manager POST:setUrl parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData>  _Nonnull formData) {
        NSDateFormatter *dateFormatter=[[NSDateFormatter alloc] init];
        [dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss a"];
        [formData appendPartWithFileData:image name:namePara fileName:[NSString stringWithFormat:@"img_%@",[dateFormatter stringFromDate:[NSDate date]]] mimeType:@"image/png"];


    } progress:^(NSProgress * _Nonnull uploadProgress) {

    } success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {

       NSLog(@"%@",responseObject);
            [GMDCircleLoader hideFromView:self.view animated:YES];
            NSMutableDictionary *dir = [[NSMutableDictionary alloc]initWithDictionary:responseObject];
            if([dir valueForKey:@"error"])
            {
                UIAlertController *alert = [[singletone sharedManager]showAlert:NSLocalizedString(@"SIGNIN", nil) :[NSString stringWithFormat: @"%@",[dir valueForKey:@"error"]] ];
                [self.parentViewController presentViewController:alert animated:YES completion:nil];
            }
            else
            {
                //Successfull
                UIAlertController *alertController = [UIAlertController alertControllerWithTitle:NSLocalizedString(@"REGISTRATION", nil) message:[dir valueForKey:@"success"] preferredStyle:UIAlertControllerStyleAlert];
                UIAlertAction* ok = [UIAlertAction actionWithTitle:NSLocalizedString(@"OK", nil) style:UIAlertActionStyleCancel handler:^(UIAlertAction * action)
                {
                    [self.navigationController popViewControllerAnimated:YES];
                }];
            [alertController addAction:ok];
            [self presentViewController:alertController animated:YES completion:nil];
            }
            NSLog(@"response object : %@",responseObject);
    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
        NSLog(@"error: %@", error.localizedDescription);

    }];

still it's not done. error : "Error in uploading image"; – ios Developer Aug 31 '16 at 09:46 — ios Developer, Aug 31 '16 at 09:46

NSData *nsdataFromBase64String = [[NSData alloc] initWithBase64EncodedString:"your image as base64 encoded" options:0];

NSDictionary *parameters = [NSMutableDictionary dictionary];

parameters = [NSDictionary dictionaryWithObjectsAndKeys:@"wr34", @"delivery_company_name", @"uname", @"user_name", @"123456789", @"contact_info", @"test1342@test.com", @"email",@"123456", @"password",@"SUV", @"car_type",@"White", @"car_color",@"GJ-1AE-2255", @"car_plate_no",@"43345dw", @"car_reg_no",@"123454", @"license_no",@"Model", @"car_model",@"location", @"location",@"4.3", @"latitude",@"8.7", @"longitude",@"notes", @"deliver_terms_conditions",@"notes", @"notes", nil];

AFHTTPSessionManager *manager = [[AFHTTPSessionManager alloc] initWithBaseURL:[NSURL URLWithString:stringURL]];
manager.responseSerializer = [AFJSONResponseSerializer serializer];
manager.requestSerializer = [AFJSONRequestSerializer serializer];

[manager POST:stringURL parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData)
 {
     //do not put image inside parameters dictionary as I did, but append it!
     [formData appendPartWithFileData:nsdataFromBase64String name:@"ToyotaSupra" fileName:@"ToyotaSupra" mimeType:@"image/png"];

 }
      success:^(NSURLSessionDataTask *task, id responseObject)
 {
     imgRes=@"success";
     //here is place for code executed in success case
 }
      failure:^(NSURLSessionDataTask *task, NSError *error)

[manager POST:stringURL parameters:parameters constructingBodyWithBlock:^(id formData) is deprecated from your code. i am trying with same code previous it's working fine. but after this deprecated warning. it's not working. — ios Developer, Aug 31 '16 at 10:53
