Question

Actually i have json parameter
[dictionary setObject:_dateOfBirth.text forKey:#"birth_date"];
[dictionary setObject:_tfCountry.text forKey:#"country"];
[dictionary setObject:_tfEmail.text forKey:#"email"];
[dictionary setObject:#"" forKey:#"fromLogin"];
[dictionary setObject:#1 forKey:#"gender"];
[dictionary setObject:#"signup" forKey:#"methodName"];

[dictionary setObject:_tfName.text forKey:#"name"];
[dictionary setObject:_tfNickName.text forKey:#"nickname"];
[dictionary setObject:_tfPassword.text forKey:#"password"];
[dictionary setObject:_tfPinCode.text forKey:#"pincode"];
There Is also a Image that i have to set profile_pic as a Key.
Now I have Converted all Parameter as a data and POst That Data lie This
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:dictionary options:kNilOptions error:nil];
// this is your service request url
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:#"http://proteen2.inexture.com/webservice"]];
// set the content as format
[request setHTTPMethod:#"POST"];
[request setHTTPBody: jsonData];
// this is your response type
[request setValue:#"application/json;charset=UTF-8" forHTTPHeaderField:#"content-type"];
NSError *err;
NSURLResponse *response;
// send the synchronous connection
NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&err];
// here add your server response NSJSONSerialization
NSArray *jsonArray = [NSJSONSerialization JSONObjectWithData:responseData options: NSJSONReadingMutableContainers error: &err];
It's Works fine for Text, Now how to attach Image to that Parameter, I am only aware with Multi Part but not getting that Point. Please Help

You need to manage many thing here, like set boundry append image data etc etc.
You should use AFNetworking to make is very simple. Download from github and just drag and drop library to your project and import AFNetworking.h in your class and then you can do something like,
NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer]multipartFormRequestWithMethod:#"POST" URLString:#"urlstring" parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> _Nonnull formData) {
//Append image here for example;
UIImage *img = tempImageView.image;
NSData *imgData = UIImageJPEGRepresentation(img, 0.5);
[formData appendPartWithFileData:imgData name:#"imagename/serversideparameter" fileName:#"imagename" mimeType:#"image/jpeg"];
} error:nil];
//Send this request to server. Something like,
NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
AFURLSessionManager *manager = [[AFURLSessionManager alloc]initWithSessionConfiguration:configuration];
[[manager dataTaskWithRequest:request completionHandler:^(NSURLResponse * _Nonnull response, id _Nullable responseObject, NSError * _Nullable error) {
if (!error) {
NSLog(#"success!!");
NSLog(#"here is the response : %#",responseObject);
}
else{
NSLog(#"Error Occured : %#",error.localizedDescription);
}
}]resume];
You shouldn't use NSUrlConnection because it is deprecated now. It's better to use NSUrlSession which i have used in answer via AFNetworking.
If you don't want to use AFNetworking then refer this stackoverflow post. It have great explanation step by step in answer.
