The same thing, so it doesn't really adduce any further evidence (unless you
know of a documented API contract that covers this situation).
However, it occurs to me there's a better solution. Since we're talking about
ARC, this pattern:
+ (id) createBlaWithFoo: (NSString*) foo // or the return type can be Bla* if
you want
{
if (!foo)
return nil;
else
return [[Bla alloc] initWithFoo: foo];
}
is superior all round. It has no autorelease penalty, may reduce the number of
keystrokes at the call site, and is impervious to the particular exploding
dealloc problem we've been discussing.
