Lack of private methods is a serious flaw in Obj-C IMO. There are
just as many reasons why someone would want to make a variable private
as they would want to make a method private. For example if your
writing a class that is part of a library that other developers will
be using (quite common in large projects). You may want to hide
implementation details from them, or prevent them from calling a
method that requires another to be called before/after it in order to
work properly etc (in other words, prevent them from shooting
themselves in the foot by calling methods they shouldn't be). Being
able to do this type of thing is one of the more powerful/useful
features of C++ IMO.

It's not possible to do this. ObjC will allow you to send any
message to any other object. The best you can do is not publicly
expose the method and that is exactly what the Cocoa framework does.
To be honest, trying to use C++ just for this seems a waste of time;
perhaps you should explain why you want to do this? Is it to try and
partition your code up, is this something that really MUST stop,
say, plugins from accessing the code?

How do I make a method private?
I have tried putting @private before the method that I want to make
private but the compiler flags a parse error. I read the
documentation and I can only find reference to private member
variables. I want to make sure that a method can only be accessed
via another method in the same class. Is this possible in Objective-
C or do I need to write this class in C++?
Many thanks.
Phil.
