Non-ARC implementation Query

Question

Apple document Advanced Memory Management Programming Guide state that -

"a 'parent' object should maintain strong references to its 'children', and that the children should have weak references to their parents"

Implementation of this is understood while using ARC. How am I supposed to implement it when I am not using ARC.

Answer 1

Parent object should retain the child object. Child object should only be having assign relation to parent.
