将数据存储在“自定义字段"中或将附件存储在ics iCal文件中 [英] Store data in Custom Fields or attachment in ics iCal file
问题描述
我需要为手动构建的iCal文件(.ics)提供一些其他信息，而这些信息我实际上我不想让Calendar应用程序用户看到.因此，我需要能够在iOS应用程序中创建事件并(随后)从Calendar事件中读取它们时手动设置它们.
I need to give my manually built iCal file (.ics) some additional infos which I actually don't want to be visible for Calendar app users. Thus I need to be able to set them manually when creating an Event in an iOS application and (later) reading them from the Calendar events.
我想知道是否可以向iCal/.ics文件本身添加自定义字段/属性(而不是通过使用日历应用程序！).它们不会显示在Calendar应用程序中，但作为我的移动应用程序开发人员可以在设备上从日历中读取ID，引用和其他内容时进行访问...直到现在，唯一的可能性似乎是存储这些值作为说明/笔记，但我对此绝对不满意！有任何可能性吗?现在，我既无法实现它，也无法在互联网上找到任何有用的东西...
I was wondering whether it is possible to add custom fields / attributes to a iCal / .ics file itself (not by using a calendar application!). They shall not be displayed in a Calendar application but accessible for me as a mobile app developer to store IDs, references, anything when I read them out from a calendar on the device... Until now the only possibility seems to be storing those vales as description / notes, but I'm definitely not happy with that! Is there any possibilltity? Neither could I achieve it by now nor did I find anything useful on the internet...
作为替代方案，我正在考虑使用iCal的附件功能，不幸的是，该功能仅对受邀人员和组织者本人可见，并且在编辑时可能无法编辑/更新.
As an alternative, I was thinking about using the Attachment function of iCal, which - unfortunately - is visible for invited persons and the organizer himself and may not be editable / updated when edited...
提前谢谢！

推荐答案
您可以定义自己的属性和参数.只要确保它们以"X-"开头即可.例如:
You can define your own properties and parameters. Just make sure they start with "X-". For example:
BEGIN:VEVENT
UID;X-FOO=bar:38F0C7FE-9711-437F-A5FE-E670E97C6766
X-SUPER-SECRET:abc123
