Does “self.propery = [[SomeClass alloc] init];” leak memory?

Question

Is it safe in Objective-C to write

self.propery = [[SomeClass alloc] init];

instead of

SomeClass *tmp = [[SomeClass alloc] init         


        

Answer 1

The first one will leak.

You must release or autorelease anything you [[ alloc] init] when you don't need it anymore.
