NHCalendarActivity

NHCalendarActivity is an easy to use custom UIActivity (iOS 6+) that adds events and alarms to the iOS calendar.

How to install it?

CocoaPods is the easiest way to install NHCalendarActivity. Run pod search NHCalendarActivity to search for the latest version. Then, copy and paste the pod line to your Podfile. Your podfile should look like:

platform :ios, '6.0'
pod 'NHCalendarActivity', '~> 0.0.1'

Finally, install it by running pod install.

How to use it?

First, create a NHCalendarEvent instance of an event (note that you can include alarms):

-(NHCalendarEvent *)createCalendarEvent
{
    NHCalendarEvent *calendarEvent = [[NHCalendarEvent alloc] init];

    calendarEvent.title = @"Long-expected Party";
    calendarEvent.location = @"The Shire";
    calendarEvent.notes = @"Bilbo's eleventy-first birthday.";
    calendarEvent.startDate = [NSDate dateWithTimeIntervalSinceNow:3600];
    calendarEvent.endDate = [NSDate dateWithTimeInterval:3600
                                               sinceDate:calendarEvent.startDate];
    calendarEvent.allDay = NO;

    // Add alarm
    NSArray *alarms = @[
        [EKAlarm alarmWithRelativeOffset:- 60.0f * 60.0f * 24],  // 1 day before
        [EKAlarm alarmWithRelativeOffset:- 60.0f * 15.0f]        // 15 minutes before
    ];
    calendarEvent.alarms = alarms;

    return calendarEvent;
}

Then, initialize the UIActivityViewController using both NHCalendarEvent and NHCalendarActivity:

- (IBAction)openBtnTouched:(id)sender
{
    NSString *msg = NSLocalizedString(@"NHCalendarActivity", nil);
    NSURL* url = [NSURL URLWithString:@"http://git.io/LV7YIQ"];

    NSArray *activities = @[
        [[NHCalendarActivity alloc] init]
    ];

    NSArray *items = @[
        msg,
        url,
        [self createCalendarEvent]
    ];

    UIActivityViewController* activity = [[UIActivityViewController alloc] initWithActivityItems:items
                                                                           applicationActivities:activities];

    [self presentViewController:activity
                       animated:YES
                     completion:NULL];    
}

There's also a NHCalendarActivityDelegate protocol, which can be used to perform additional actions:

#pragma mark - NHCalendarActivityDelegate

-(void)calendarActivityDidFinish:(NHCalendarEvent *)event
{
    NSLog(@"Event created from %@ to %@", event.startDate, event.endDate);
}

-(void)calendarActivityDidFail:(NHCalendarEvent *)event
                     withError:(NSError *)error
{
    NSLog(@"Ops!");
}

- (void)calendarActivityDidFailWithError:(NSError *)error
{
    NSLog(@"Ops!");
}

And that's all.
