I'd like to open the iphone calendar app programmatically from within my app. According to this post: How to open the iPhone calendar from within my app? it isn't possible (May 22 2010!). Maybe the ios sdk 4 or ios sdk 5 support such a feature?
It's not possible, except for using
UIDocumentInteractionController with an .ical file, but that's pretty pointless as you could achieve the same (adding an event) by using Event Kit.
