If I do something like:
varName = [dictionaryName objectForKey:@"keyName"];
does that return a copy of what is in the dictionary?
No.
or a pointer?
That should have been:
All objects are passed as pointers
This method follows the normal Cocoa memory management rules. The
object did
not come from an alloc..., copy... or new... method, and you didn't
retain it yourself, so you do not own a reference to it. If you want
it to stick around longer than the dictionary itself, it's up to you
to either make a copy
