try this code,hope it helps you. . . . . . .. . . . . ..

    NSString *baseurl = @"Enter URL here";

NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];

//Set Params
[request setHTTPShouldHandleCookies:NO];
[request setTimeoutInterval:60];
[request setHTTPMethod:@"POST"];

//Create boundary, it can be anything
NSString *boundary = @"------VohpleBoundary4QuqLuM1cE5lMwCy";

// set Content-Type in HTTP header
NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@", boundary];
[request setValue:contentType forHTTPHeaderField: @"Content-Type"];

// post body
NSMutableData *body = [NSMutableData data];

//Populate a dictionary with all the regular values you would like to send.
NSMutableDictionary* post_dict = [[NSMutableDictionary alloc] init];
[post_dict setObject:Name.text forKey:@"name"];
[post_dict setObject:ContactNameTF.text forKey:@"contactname"];
[post_dict setObject:EmailTf.text forKey:@"email"];
[post_dict setObject:PasswordTF.text forKey:@"password"];
[post_dict setObject:HouseNumberTF.text forKey:@"housenumber"];
[post_dict setObject:StreetTF.text forKey:@"street"];
[post_dict setObject:cityTF.text forKey:@"city"];
[post_dict setObject:POstcodeTF.text forKey:@"postalcode"];
[post_dict setObject:ContactNumberTF.text forKey:@"contact"];
[post_dict setObject:self.theImage forKey:@"image_url"];



// add params (all params are strings)
for (NSString *param in post_dict) {
    [body appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"%@\"\r\n\r\n", param] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[[NSString stringWithFormat:@"%@\r\n", [post_dict objectForKey:param]] dataUsingEncoding:NSUTF8StringEncoding]];
}

NSString *FileParamConstant = @"Enter Key Of Image Paramater";

NSData *imageData = UIImageJPEGRepresentation(image, 1);

//Assuming data is not nil we add this to the multipart form
if (imageData)
{
    [body appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"%@\"; filename=\"image.jpg\"\r\n", FileParamConstant] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[@"Content-Type:image/jpeg\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:imageData];
    [body appendData:[[NSString stringWithFormat:@"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
}

//Close off the request with the boundary
[body appendData:[[NSString stringWithFormat:@"--%@--\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];

// setting the body of the post to the request
[request setHTTPBody:body];

// set URL
[request setURL:[NSURL URLWithString:baseurl]];

[NSURLConnection sendAsynchronousRequest:request
                                   queue:[NSOperationQueue mainQueue]
                       completionHandler:^(NSURLResponse *response, NSData *data, NSError *error) {

                           NSString *result = [[NSString alloc]initWithData:data encoding:NSUTF8StringEncoding];
                           if ([result isEqualToString:@"true"]) {
                               [self performSelectorOnMainThread:@selector(mainViewController) withObject:nil waitUntilDone:NO];
                           }
                           else {

                               NSLog(@"%@",[[NSString alloc]initWithData:data encoding:NSUTF8StringEncoding]);
                           }

                       }];
