在Xcode中解析Google日历

Question

I am attempting to add an event schedule to an iOS / xcode app that I am working on. I have been able to parse the google calendar feed using Michael Waterfalls' code at https://github.com/mwaterfall/MWFeedParser but I have not been able to replace the date the post was created with the date the event is scheduled.

The feed url is placed in the RootViewController.m file and I am using this feed http://www.google.com/calendar/feeds/firstpentecostalchurch.com_e2hia2v3bc766ff9397qu3eqa8%40group.calendar.google.com/public/basic

I am sure this is easy, I must be missing something as the heavy lifting is already done.

Answer 1

The event dates you are looking for don't have an XML tag associated with them. That's to be expected because they aren't part of the RSS specification. The event dates are embedded in the text of the <summary> and <content> tags, which contain HTML.

It appears that the event dates at least have consistent patterns (one for recurring events and another for single events). For example, single event summaries seem to appear at the beginning in a long date format prefixed by a "When: ".

You could use regular expressions to pull out the dates, but you might have to add logic for the recurring events to calculate all the the specific dates. And if the maintainer of the feed changes their format, your interface will break. You can try to anticipate that somewhat by looking for multiple different date patterns, but that only goes so far.

我建议您改用Calendar API v3，因为不建议使用GData供稿https://developers.google.com/google-apps/calendar/v2/developers_guide_protocol
