Objective-C memory management, xml parser and other non-trivial examples

Question

I know the basic principles about memory management (retain count, autorelease pools etc) in Cocoa, but once you go past simple retain/release, it\'s getting a bit more confusin

Answer 1

@3rd question

The line "objectArray = [self loadData]; // 1 - objectArray is instance var" isn't really a setter as it accesses the instance variable directly. To use a setter one needs to access it though self

self.objectArray = [self loadData];

...and if your property is declared as (nonatomic, copy) the old objectArray will be released and a new will be created with a copy, thus being retained.
