UIDocumentInteractionController Calendar Access
问题 I have an ics (Calendar) file that I'm opening with a UIDocumentInteractionController , using presentOptionsMenuFromRect: . When this runs, the "Open In" menu looks like this. As you can see, no "Add to Calendar" option. Here's what gets me: I'm using the same exact code for a .vcf (contact card) file, and it works as expected with the "Open In Contacts" option available. Am I missing some sort of permission in my Info.plist for calendar access? Why can't UIDocumentInteractionController
