IOS 通訊錄信息讀取兼容的實現方法
項目中有一個功能需要讀取通訊錄中聯系人的手機。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更新以后，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);
其中兩個方法被干掉了（對于iOS開發者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以后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后是這個人的詳細信息。
其中：
第一個方法是選中這個人之后調用。
第二個方法是選中這個人的詳細信息后調用。
解析具體信息的代碼可以完全不變
