No it doesn't, because:

That's because you've made a silly mistake. [NSString stringWithFormat] returns 
an already autoreleased object, or one you don't own, at any rate. So you 
should not autorelease it again. The object will be sent a -release message 
twice, and on the second one, will fail with EXC_BAD_ACCESS as the object has 
already been dealloced.
