24.8. Summary

Managed memory requires some additional effort, but it isn't onerous. Just remember these basic rules:

• When storing an object reference in a persistent variable, retain it.

• Release or autorelease any retained reference before discarding it.

• Write a -dealloc method to release all retained objects.

• Always return retained or autoreleased objects.

• Autoreleased objects won't be released until after the current method has returned.
