I'm in the process of creating an app that would use iCal format calendars, most likely stored by Google in Google Calendars.

What's the best approach to achieve this? I don't really want to import my calendars in the iOS calendar app.

Should I got through the hassle to recompile the library of iOS and all that?

Thank you. Genie

  • You need to make this question much more specific before we can help you. Best approach to achieve what, exactly? Recompile what library? All what? I really have no idea what you're asking for. – Caleb Jun 28 '11 at 14:36

If you're looking for a component to build a Calendar, i think this one will work:

http://code.google.com/p/scm-subversion/source/browse/trunk/iPhone/CalendarTest/Calendar/KLCalendarView.h?spec=svn11&r=11

All months transactions, and UI designs were built and i haven't seen any better components, i think that is worthy for you to take a look.

if you're looking to build your own calendar, you could use this one as example.

    thanks for the recommendation, right now I'm looking more for the backend, to read CalDAV calendar items, store them and then use them later. – genie Jun 30 '11 at 20:26
  • Have you any screenshots of your calendar ? – booker Jun 11 '12 at 14:03

You'll need some sort of code to parse iCal calendars, so it stands to reason that you'll either write that yourself or use somebody else's code. Here's a SO question that covers building libical for iOS, with a link to a (possibly) helpful blog entry. The blog does indeed make it sound like a hassle, but as that entry is also several years old and covers iPhoneOS 2.0 (long before it was even called iOS), things may not be so bad.

There's also an Objective-C wrapper which may make using libical that much more pleasant. If you try it, please let us know how it works.

    I looked closer to this and I think the best option if I decide to go with CalDav and google would be HSCalDav, https://github.com/kdbdallas/HSCalDav, this seems to be something that would fit my needs, or use Google Web Engine and build my own calendar and use JSON to access it. This way I won't need the user to have a google account to access it's calendars. – genie Jul 06 '11 at 18:21
