14.9. Presenting Event View Controllers
Problem
You want to use the built-in iOS SDK view controllers to display the properties of an event in the Calendar database.
Solution
Create an instance of EKEventViewController
and push it into a
navigation controller or present it as a modal view controller on
another view controller.
Discussion
Users of iOS devices are already familiar with the interface
they see on the Calendar application. When they select an event, they
can see that event’s properties and they might be allowed to modify
the event. To present a view to a user using built-in iOS SDK event
view controllers, we can instantiate an object of type EKEventViewController
and assign an event of
type EKEvent
to its event property.
Once that’s done, we can push the event view controller into our
navigation controller and let iOS take care of the rest.
We want to find an event (any event) in any of the calendars
available on an iOS device, from one year ago to now. We will use
EKEventViewController
to present
that event to the user. Here is the .h file of our view controller:
#import <UIKit/UIKit.h> #import <EventKit/EventKit.h> #import <EventKitUI/EventKitUI.h> @interface Presenting_Event_View_ControllersViewController : UIViewController <EKEventViewDelegate> @property (nonatomic, strong) EKEventStore *eventStore; @end
We should now synthesize our eventStore
property in the implementation of
our view controller:
#import "Presenting_Event_View_ControllersViewController.h" @implementation ...
