在ABAddressBookSave上获取EXC_BAD_ACCESS

我正在使用以下代码将联系人从通讯簿中删除。(在iOS 5.0上)。但它每次都会给我EXC_BAD_ACCESS ABAddressBookSave(addressBook, NULL); 。我已经选择了NSZombieEnalbeld,但它仍然没有给我明确的错误。

ABAddressBookRef addressBook = ABAddressBookCreate();
 CFErrorRef error = NULL;

 ABRecordRef person = ABAddressBookCopyArrayOfAllSources(addressBook);

 BOOL success = ABAddressBookRemoveRecord(addressBook, person, &error);

 if (success)
 {
     BOOL su = ABAddressBookSave(addressBook, NULL);
     NSLog(@"Removed ----");
 }
 CFRelease(addressBook);

出了什么问题?
