To keep your memory straight, you need to remember just two things
Memory management can get pretty hairy in larger apps, so Apple has a couple of rules established to keep track of who’s in charge of releasing and retaining when.
-
You own objects you create with alloc, new, copy, or mutableCopy.
If you create an object with alloc, new, copy, or mutableCopy, it will have a retain count of 1, and you’re responsible for sending a release when you’re done with the object. You can also put the object in the autorelease pool if you want the system to handle sending a release later.
-
Assume everything else could go away at the end of the event loop unless you take ownership.
