To raise an event:

[[NSNotificationCenter defaultCenter] postNotificationName:notificationName object:someObj];

To listen for the event:

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(notificationSelector:) name:notificationName object:notificationSender];

To stop listening for the event:

[[NSNotificationCenter defaultCenter] removeObserver:self name:notificationName object:notificationSender];

add 2 frameworks
1.EventKitUI.framework
2.EventKit.framework

.m
#import <EventKitUI/EventKitUI.h>

- (IBAction)CreateEvent:(id)sender {

    //Get the even store object
    //EKEventStore *eventStore = [[EKEventStore alloc] init];
    EKEventStore *eventStore = [[EKEventStore alloc] init];

    /* iOS 6 requires the user grant your application access to the Event Stores */


     if([[UIDevice currentDevice].systemVersion floatValue] >= 6.0)// checks if device is ios6
       {
    [eventStore requestAccessToEntityType:EKEntityTypeReminder completion:^(BOOL granted, NSError *error) {
        // handle access here
    }];





    if ([eventStore respondsToSelector:@selector(requestAccessToEntityType:completion:)])
    {
        // iOS Settings > Privacy > Calendars > MY APP > ENABLE | DISABLE 
        [eventStore requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted, NSError *error)
         {
             if ( granted )
             {
