iOS bridge vs bridge_transfer

Question

I\'m confused with bridge and bridge_transfer, is this correct?

-(void)getData{
    ABAddressBookRef addressBook = ABAddressBookCreate(         


        

Answer 1

Luis Oscar I'm still working out my understanding of ARC, but I believe addressBook does need CFRelease. ARC is not managing addressBook. NSArray *allPeople is being managed by ARC via the __bridge_transfer cast hint and it is being created as a copy of the original. Without the CFRelease, addressBook will leak.
