I want to upload image with other parameters to server using objective c

well am new to iOS and i encountered a situation where i have to upload a image to server. Here is what am doing in the post method.

- (IBAction)submitClicked:(UIButton *)sender {

    NSDictionary *inputData = [NSDictionary dictionaryWithObjectsAndKeys:myImage,@"coverPic", nil];

NSError *error;
NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *session = [NSURLSession sessionWithConfiguration:configuration delegate:nil delegateQueue:nil];
NSURL *url = [NSURL URLWithString:@"http://api.mapartment.in/index.php/events/create"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url
                                                       cachePolicy:NSURLRequestUseProtocolCachePolicy
                                                   timeoutInterval:70.0];

[request addValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[request addValue:@"application/json" forHTTPHeaderField:@"Accept"];
[request setHTTPMethod:@"POST"];

NSData *jsonInputData = [NSJSONSerialization dataWithJSONObject:inputData options:NSJSONWritingPrettyPrinted error:&error];

NSString *jsonInputString = [[NSString alloc] initWithData:jsonInputData encoding:NSUTF8StringEncoding];

[request setHTTPBody:[jsonInputString dataUsingEncoding:NSUTF8StringEncoding]];

NSURLSessionDataTask *postDataTask = [session dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error){


    dispatch_async(dispatch_get_main_queue(), ^{

        NSDictionary *jsondictcity_name = [NSJSONSerialization JSONObjectWithData:data options:0 error:NULL];

        if([[jsondictcity_name valueForKey:@"result"] isEqual:@"true"]){

            NSLog(@"Success");

        }

        else{

            NSLog(@"Try Again");
        }

        [self.view resignFirstResponder];

    });
}

                                      ];
[postDataTask resume];

}

P.S. _localFilePath contains - /Users/appcode/Library/Developer/CoreSimulator/Devices/3C3567B8-03BC-4233-B0BC-97E3899D0AAA/data/Containers/Data/Application/3D574024-42FB-4305-807A-ACC3C128383F/Documents/png

Image will not pass with other parameter,you have to convert image into NSData

   UIImage *yourImage= [UIImage imageNamed:@"image.png"];
   NSData *imageData = UIImagePNGRepresentation(yourImage);
   NSString *postLength = [NSString stringWithFormat:@"%d", [imageData length]];

and then pass these data in request

 [request setValue:postLength forHTTPHeaderField:@"Content-Length"];
 [request setHTTPBody:imageData];

and other parameter pass as json.

to get UIImage from path use

 UIImage *yourImage = [UIImage imageWithContentsOfFile: imageFilePath];
