Correct URL encoding in Cocoa (ObjC)

Question

I am trying to URL encode an NSString but I can't seem to find the proper way (I'm new to Obj C). I have been searching around but can't find a decent answer. So:

What is the correct, and modern, way to encode an NSString like a URL?

Thanks in advance.

Encoding to UTF-8:

NSString *strUTF8 = [urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

Wrong answer. Translates "This is my + statement. Got it?" to "This%20is%20my%20+%20statement.%20Got%20it?" instead of "This+is+my+%2B+statement.+Got+it%3F". Note it doesn't properly encoded the plus and the question mark characters. – Volomike Jul 15 '16 at 07:00
