Question

I found this strange thing. XCode instruments tell me that this line

return (SDZPerson*)[[[SDZPerson alloc] initWithNode: node] autorelease];

leaks. But if i change it to:

SDZPerson* person = [[[SDZPerson alloc] initWithNode: node] autorelease];
return person;

Instruments no longer report leak in this place. Is it really a leak or is it nothing?

Thank you all in advance.

Answer 1

Even if the two code snippets are slightly different (the 1st one contain a typecasting), I doubt the instruments indicate this as a leak due to the autorelease in the return statement.

Adding autorelease in the return statement can be used.

You should give it a try to

SDZPerson* person = [[SDZPerson alloc] init];
/** do your stuff here if needed */
return [person autorelease];

or even

return [[[SDZPerson alloc] init] autorelease;
