Passed string from the another ViewController is not working with NSUrl - ios

Question

I am getting the PassedUserId value from another view.I can print the value in log. but its not assigning to the url string. Here i am trying to pass the text along with image.
NSString *requestString =[NSString stringWithFormat:#"UserId=%#&CategoryId=%#&Continent=%#&Country=%#&City=%#&Gender=%#&ImageName=%#&AgeRange=%#",PassedUserId,CategoryId,continentTextfield.text,countrytextfield.text,citytextfield.text,gender,imagename,ageTextfield.text];
NSString *url=[NSString stringWithFormat:#"http://192.168.2.4:98/UserImage.svc/InsertFacialImage?%#",requestString];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init] ;
[request setURL:[NSURL URLWithString:url]];
[request setHTTPMethod:#"POST"];
// Create 'POST' MutableRequest with Data and Other Image Attachment.
NSString *boundary = #"---------------------------14737809831466499882746641449";
NSString *contentType = [NSString stringWithFormat:#"multipart/form-data; boundary=%#", boundary];
[request setValue:contentType forHTTPHeaderField:#"Content-Type"];
NSData *data = UIImageJPEGRepresentation(chosenImage, 0.2f);
[request addValue:#"image/JPEG" forHTTPHeaderField:#"Content-Type"];
NSMutableData *body = [NSMutableData data];
[body appendData:[NSData dataWithData:data]];
[request setHTTPBody:body];
NSData *returnData;
NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
NSLog(#"Ret: %#",returnString);

Answer 1

The first thing I noticed is that you have swapped the two values:
stringWithFormat:#"UserId=%#&CategoryId=%#...",CategoryId,PassedUserId
Could you be more specific about what datatypes the CategoryId and PassedUserId have?
If they're strings, you're doing it right. If they are datatype integer though, you should use %i instead of %#.
