As long as you release them properly, you can just use NSAray/NSMutableArray:
[array addObject: CFBridgingRelease(cfObject)];
After the CFBridgingRelease, the CF-retain count is decremented, and NSArray
becomes responsible for its lifetime. (this also means that there is no need to
release the cfObject in your dealloc; that will be handled automatically when
the array itself is deallocated (or when the cfObject is removed from the array)
When you want to get the object in the array, you can just use a __bridge cast:
CFTypeRef cfObject = (__bridge CFTypeRef)[array objectAtIndex: foo]l
This doesn’t affect the object’s retain count, so it is equivalent to a Get*()
function in CoreFoundation. If you want the equivalent of a Copy*() function,
you can use:
CFTypeRef cfObject = CFBridgingRetain([array objectAtIndex: foo]);
