I am getting warnings when adding integers in the array and assigning
the integer ID as a key. The code does work though, but I am guessing
there is a better way to accomplish what I want. I know that these
methods are expecting pointers as parameters and I am passing a
scalar. So, what's the best way to approach that?
Actually, as the documentation specifies, setObject:forKey: expects an
object that conforms to the NSCopying protocol as the key parameter.
Keys are copied when objects are inserted.
You could use an NSNumber, e.g.:
[result setObject:... forKey:[NSNumber numberWithInt:ID]];
