iOS8通訊錄資訊讀取相容，ios8通訊錄讀取

項目中有一個功能需要讀取通訊錄中連絡人的手機。在iOS8以前都是可用的，主要使用如下三個代理方法來實現

- (void) peoplePickerNavigationControllerDidCancel:(ABPeoplePickerNavigationController *)peoplePicker

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

- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier{    return NO;}

但是iOS8更新以後，悲劇的事情發生了：

// Deprecated, use predicateForSelectionOfPerson and/or -peoplePickerNavigationController:didSelectPerson: instead.- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person NS_DEPRECATED_IOS(2_0, 8_0);// Deprecated, use predicateForSelectionOfProperty and/or -peoplePickerNavigationController:didSelectPerson:property:identifier: instead.- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier NS_DEPRECATED_IOS(2_0, 8_0);

其中兩個方法被幹掉了（對於iOS開發人員來說來說這種情況太常見了）

參考文檔發現可以使用如下兩個方法來代替：

// Called after a person has been selected by the user.- (void)peoplePickerNavigationController:(ABPeoplePickerNavigationController*)peoplePicker didSelectPerson:(ABRecordRef)person NS_AVAILABLE_IOS(8_0);// Called after a property has been selected by the user.- (void)peoplePickerNavigationController:(ABPeoplePickerNavigationController*)peoplePicker didSelectPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier NS_AVAILABLE_IOS(8_0);

這兩個方法是這樣的，因為iOS8以後通訊錄的結構有所變化：第一層是人名列表，點擊某個人名進去之後是這個人的詳細資料。

其中：

第一個方法是選中這個人之後調用。

第二個方法是選中這個人的詳細資料後調用。
