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 example leaks unless you provide a custom property setter. You can use:

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

Instead.
