newPersonViewController.newPersonViewDelegate = delegate;
newPersonViewController.displayedPerson = addressBookRecord;

？
是否有标准CoreFoundation
Is there a standard CoreFoundation pattern around this I'm not aware of?
推荐答案
我认为调用CFRelease是不安全的。
displayedPerson在标题中定义如下。
所以，显示的person只是分配，而不是复制或保留，当我们设置的值。
因此，我想我们可以' t释放它。
I don't think it's safe to call CFRelease.
displayedPerson is defined as follows in the header.
So, displayedPerson is just assigned and not copied or retained when we set the value.
Therefore, I think we can't release it.
@property(nonatomic, readwrite) ABRecordRef displayedPerson
