Releasing Core Foundation object references

Question

Do I need to release a Core Foundation objects to clear up memory? And if so, how?

For example, in the code:

ABAddressBookRef addressBook = ABAddressBook         


        

Answer 1

For ARC you can use.

return (__bridge_transfer NSArray*)peopleArray;

"__bridge_transfer" will transfer the ownership to ARC and therefore you don't need any further release call.
