I feel like I've asked this before, but I don't feel I'm grasping the answer.
Why don't these work the same way under ARC:
NSString* answer = @42;
int ans = CFStringGetIntValue((CFStringRef)answer);
and
NSURL* imageSource = [NSURL new];
CGImageSourceRef src =
My take:
__bridge means 'do not transfer the retain count of whatever on the RHS to
the LHS'. If the RHS involves some kind of create or new, then you'll get a
leak since ARC won't release it.
__bridge_transfer means 'transfer the retain count of whatever on the RHS to
the LHS'. If the RHS
The first gives me the following error:
Implicit conversion of Objective-C pointer type 'NSString *' to C pointer type
'CFStringRef' (aka 'const struct __CFString *') requires a bridged cast

It's effectively a singleton. It doesn't mater how it's bridged because it
can't be released. The second is a new NSURL that is allocated on the heap. It
needs to be released so it needs to be bridged correctly to

But CGImageSourceCreateWithURL() includes the keyword 'create' - so the
object you get back has a retain count of 1. ARC will insist that you cast
with __bridge or __bridge_transfer.
ARC isn't involved with the
Argh. Okay, I'll ask this on devforums when it comes back up, in case it
depends on, uh, the thing I'm using that I can't talk about. m.
