I hope i did not skip this part in the ObjC manual but is it possible to refer to a class from within one of its class methods? Like in PHP you would use "this" to refer to the current instance, while "self" refers to the instance's class the ObjC equivalent of "this" would be "self", so what would be the ObjC equivalent of PHP's "self",...
I have a class with a method that returns a hash. Ordinarily, I would get the result like so: %resp = $myclass->sub($foo); And then access members of the returned hash like this: $resp{key}{subkey}; in the case of a 2d hash. I figure there must be a way to combine this into a single, elegant line, something like this: $myclass->...

Say I have class A and B, whereas B is a descendant of A with different functionality (i.e. can't be used as a substitute for A during runtime) and need a class C, which combines A and B, uses both and provides a unique interface to users...

I currently have a solution with multiple projects that mostly use the same classes. As a result, it appeared to me that it would be a good idea to add a class library containing these classes in the solution instead of repeating the class in each project. However, one project I have requires a few additional properties to some of the ...
