How to create CFArrayRef

Question

I am trying to convert only one iPhone contact to vCard using the built-in methods. The docs say use:

ABPersonCreateVCardRepresentationWithPeople(CFArrayRef people) 

... but my delegate method gives me the following:

 - (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person; 

I cannot figure out how to create a CFArrayRef with just one ABRecordRef .

The docs pointed me to CFArrayCreate() , which confused me even more. I don't know enough C to figure it out on my own. I read at SO that NSArray had something called a duty free bridge and should be interchangeable with CFArrayRef , but didn't quite understand how to use it, since the compiler complained when I tried to just replace them.

Answer 1

free bridge:

where array is the type of class: NSArray

 CFArrayRef arrayRef = (__bridge CFArrayRef)array;
