Is it safe in Objective-C to write

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

instead of

SomeClass *tmp = [[SomeClass alloc] init];
self.property = tmp;
[tmp release];

or will the first form leak memory?

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

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