I just wanted to know: will the retain count of an object be incremented if it is added to an array or dictionary in Objective-C? Can I release a particular object immediately after adding it to an array or dictionary?

Hariprasad,
NS[collection name here] retain objects added to them as NSResponder noted. A few other facts:
after adding”, the short answer is
yes. Often times I do an
autoreleasefor objects that arebound for containment in a
collection and won’t be needed outside the collection.
object from a collection, the
reference count is decremented. If
you want to ensure it won’t be
deleted from memory (next pool
sweep) you need to retain the
object.
