What is the best way to solve an Objective-C namespace collision?
Objective-C has no namespaces; it's much like C, everything is within one global namespace. Common practice is to prefix classes with initials, e.g. if you are working at IBM, you could prefix them with "IBM"; if you work for Microsoft, you could use "MS"; and so on. Sometimes the initials refer to the project, e.g. Adium prefixes classes with "AI" (as there is no company behind it of that you cou

Q: How can I write a method that takes a variable number of arguments, like NSString's +stringWithFormat:? A: Methods that take variable arguments are known as variadic methods. Keep in mind that the implementation of an Objective-C method is just a block of code, like a C function. The variadic argument macros described in the stdarg(3) manual page work the same way in a method as they do in an o
