Hi all,
I am trying to create my own shape classes (sphere, cube etc) with an
abstract class called shape in order that I implement polymorphism. I
need however a container class. Coming from a C++ background, I would
normally use the STL vector class to do this. How might one produce a
similar result in Obj-C?
I believe that the analog of a vector in the STL is an NSMutableArray in
Foundation. Be aware, though, that you can only store objects (or, more
precisely, pointers to objects) in an NSMutableArray; you can't store
primitive types like ints.
However, you can store wrapped ints (NSNumber), wrapped binary data
(NSData) and so on.
