What is Objective C Keyword id ?

By | March 6, 2011


Objective C uses a special keyword ‘id’.
Let’s see what it is.
Objective C -id- is actually a ‘pointer to an object’. That is ‘id’ can hold a pointer to any objective c object. It doesn’t matter the object’s class.

NSString *myString = @"Coderz Heaven!";
id newString;
NSString *tempString;

That’s it! It will work out with using ‘id’ keyword. Compiler simply thinks ‘you know what you are doing!’

A word of caution : Remember not to use * while creating id objects! Because that type already know it’s a pointer!
