阅读更多关于 EKAlarm will not set in iOS 5

问题 I wrote the following snippet to create an event. Setting the alarm works fine in iOS 4, but in iOS 5 it doesn't get set. Is this a bug or am I missing something?

How to identify EKEvent uniquely with Sync across the devices

阅读更多关于 How to identify EKEvent uniquely with Sync across the devices

I am trying to make Event Syncing feature for a Project. I need to sync events with the remote server. Let's say I Installed the App in Device A. If I login to another device lets take B, then events synced from A should also appear in Device B, and events of B should also be synced. Now if I again login into the Device A, Events of B should be added. But events previously from A should not again be added to Device A again For this I decided to keep its eventIdentifier on the remote database. The Issue now happens when I again Go back to Device B, where events previously synced from Device A

Modifying EKParticipants (attendees) in EventKit like Sunrise

阅读更多关于 Modifying EKParticipants (attendees) in EventKit like Sunrise

My goal is to add some invitees to an EKEvent . I've looked into other questions like this, such as this one , but all say that it is essentially impossible to add EKParticipant s to an EKEvent programmatically. I do see that the attendees property is read-only, but I see other services like Sunrise using it in their mobile app. I'm confident that they're using some system that at least partially integrates with EventKit because they're pulling in calendars from the user's iCal app. Invites sent from an added Exchange account, for example, are also clearly sent by the Exchange service as

How to programmatically add calendar subscriptions on iOS?

阅读更多关于 How to programmatically add calendar subscriptions on iOS?

问题 Via the settings panel of your iPhone, you can add a subscription to a remote .ics calendar format. I have a Dutch iPhone app that does this from within the app (see the screenshot below, "abonneren op de agenda" means "subscribe to the calendar"), but there must be others too. I want to mimic this behavior for a project of mine, but I can't find the API to do this with. It looks like it's not a part of EventKit, but because there's no app switching going on when you hit 'subscribe' in the

Programmatically add custom event in the iPhone Calendar

阅读更多关于 Programmatically add custom event in the iPhone Calendar

问题 Is there any way to add iCal event to the iPhone Calendar from the custom App? 回答1: Based on Apple Documentation, this has changed a bit as of iOS 6.0. 1) You should request access to the user's calendar via "requestAccessToEntityType:completion:" and execute the event handling inside of a block. 2) You need to commit your event now or pass the "commit" param to your save/remove call Everything else stays the same... Add the EventKit framework and #import <EventKit/EventKit.h> to your code.
