I’m using ARC, and my application compiles and works without crashing. However, when I run an Analyze build, I am seeing these warnings. I come from PHP and JavaScript so naturally I have no idea what to do to fix this stuff. Can anyone help me out?

    ARC needs some help when dealing with Core Foundation. Try this:

    NSArray *linkedPeople = (__bridge_transfer NSArray *)ABPersonCopyArrayOfAllLinkedPeople(person);

    and

    NSDictionary *personDictionary = (__bridge_transfer NSDictionary *)(ABMultiValueCopyValueAtIndex(addressFromPerson, 0));

    __bridge_transfer tells ARC that a non-Objective-C (i.e., Core Foundation) pointer is being moved to an Objective-C pointer, and it allows ARC to take ownership of the object for memory management purposes. CF functions with the word “copy” in them produce an object reference with a +1 reference count. If you don’t explicitly call CFRelease() on the object later, then it will leak. Using __bridge_transfer, however, lets ARC do this for you.

    (Note: I didn’t test this, but I believe those are the issues that the static analyzer is complaining about.)
