baidu搜的都是什么垃圾东西，还得自己查

字面意思是：获取联系人时未请求属性

然后查看CNContact对象，果然，因为后面需要用到phoneNumbers属性，查询时并没有带key

解决办法:需要用到哪个属性查询时带对应key值，比如CNContactPhoneNumbersKey

过滤时
    NSPredicate *predicate = [CNContact predicateForContactsMatchingName:organizationName];
    //过滤的条件
    NSArray *keysToFetch = @[CNContactPhoneNumbersKey,CNContactEmailAddressesKey, [CNContactFormatter descriptorForRequiredKeysForStyle:CNContactFormatterStyleFullName]];
    NSArray *contact = [store unifiedContactsMatchingPredicate:predicate keysToFetch:keysToFetch error:nil];

所有key值如下

CONTACTS_EXTERN NSString * const CNContactPropertyNotFetchedExceptionName;

// Properties that are always fetched. Can be used with key value coding and observing.
CONTACTS_EXTERN NSString * const CNContactIdentifierKey                      NS_AVAILABLE(10_11, 9_0);

// Optional properties that can be fetched. Can be used with key value coding and observing.
