can you do this?
CFMutableDictionaryRef tokenByParent = CFDictionaryCreateMutable( NULL,
0, &kCFTypeDictionaryKeyCallBacks, &kCFTypeDictionaryValueCallBacks );
[ (NSMutableDictionary*)tokenByParent autorelease ];
with of course the desire to continue using tokenByParent in the routine.
CFMutableDictionaryRef is toll-free bridged with NSMutableDictionary but does
that that extend to autoreleasing it?
Normally I balance alloc/init with release and CF..Create.. with CFRelease(),
in this case I have deeply nested code iterating over a database and there are
multiple ways it can fail, I'm testing for the failures and returning
appropriate errors but don't want to have to deal with figuring out what I need
to release at 10 different exit points to the routine so I'd like to just use
autorelease and let someone else worry about it. The alternative is either
massive nested if() code or abusing @try/@finally with no @catch to release
everything on the way out the door.
Is it ok to cast a CF object to an NS object for the purpose of autoreleasing
it? _______________________________________________
