First of all: thank you. You solved my problem.
There's no real way to enforce privateness, either in Objective-C
or C++.
Why not in C++?
And why not in Obj-C ? The new runtime (64 bits, non-fragile) declare
a symbol for each ivar. Private ivars are not exported by default, so
you cannot access them without running into a linker error.
That said, if you know the layout of a specific object (either in C++
and Obj-C) you can cast it into a blob and access the memory directly.
That's maybe why he said you cannot enforce privateness.
