I assume that just because I can toll-free bridge something
between core foundation and NSFoo I still have to worry about
CFretain/CFrelease in a GC app. Correct?
Example:
Assume image is an CGImageSourceRef.
NSDictionary *metadata =
(NSDictionary *) CGImageSourceCopyPropertiesAtIndex(image, 0, NULL);
....
CFRelease((CFDictionaryRef) metadata);
or alternately
NSDictionary *metadata = (NSDictionary *)
NSMakeCollectable(CGImageSourceCopyPropertiesAtIndex(image, 0, NULL));
Is that correct?
