  Using Address Book View Controllers in Your App
  
  07:01
- You've seen how to retrieve contact information using the people picker and have used this approach to retrieve and display the photo of a chosen contact. In this video we'll take a look at using Address Book UI framework view controllers to allow a user to add a new contact to their address book from within your app.
  
  Adding New Contacts
  
  03:39
- In the last exercise we covered using the Address Book UI framework to allow users of our apps to add new address book contacts from within those apps. In this lesson you'll learn how to save references to contact data within an app in order to display saved contact data upon start of the app.
  
  Saving Contact Data in Your App
  
  06:00
- Address Book-enabled applications have access to a user's contact data. What better way to use that contact data than to allow our users to communicate with their contacts from within our apps? In this exercise you'll learn how to do just that by sending in-app SMS messages from our TopContact app!
  
  Using Address Book Contact Data: Sending SMS Messages
  
  08:43
Does your app need to create calendar events or to access a user's calendar? This chapter will show you how you can use the Event Kit and Event Kit UI frameworks to do just that.

Calendars and Notifications
- This video covers the Event Kit and Event Kit UI frameworks and describes how you can create or work with a user's calendar data from within your application.
  
  Event Kit Overview
  
  08:07
- The Event Kit UI framework provides us with a set of the view controllers our users already know from the Calendar application. In this lesson you'll learn how to use these view controllers to build a simple weekly view calendar called ThisWeek.
  
  Using Event View Controllers
  
  11:07
- The Event Kit framework allows us to access a user's calendars and also to create and edit events. The Event Kit UI framework provides us with a set of the view controllers our users already know from the calendar application. In this video you'll see how to use both frameworks within your app to allow a user to create a new event in their calendar and then to view that event using a provided view controller.
  
  Adding, Updating, and Deleting Events
  
  09:49
- In the last exercise you learned how to create a new event in a user's default calendar. In this lesson you'll learn how to change the code you wrote to schedule a recurring event.
  
  Creating Recurring Events
  
  02:51
- This video draws the distinction between calendar alerts and local notifications and their correct usage as reminders, alarms, or to notify users of important events in your applications.
  
  Implementing Reminders with Local Notifications
  
  03:27
- Reacting to changes to a user's calendar from external applications is extremely important. This lesson highlights the best approach to take in ensuring that your applications react correctly to such changes.

Email
- This video will give you an overview of the Message UI framework and how it can be used to add email functionality to your applications.
  
  Email Overview
  
  02:01
- In this lesson we'll adapt our TopContact app from Chapter 3 to send email instead of SMS. Both SMS and email are supported by the MessageUI Framework and so this adaptation is quite easy to implement.
  
  Sending Email
  
  07:25
- Once you've added in-app email functionality to an app you're likely to find a time when you also need to send an attachment along with the email. In this video you'll see how we can adapt the TopContact App from the previous exercise to do just that with only a minor code addition.
  
  Sending Attachments
  
  02:46
- If you're going to implement in-app email functionality, you'll need to know how to detect and react to any errors that may occur. While we've come to expect that email simply works most of the time, there are numerous reasons why email composed on and sent from mobile devices may simply fail, as you'll see in this video.
  
  Dealing with Email Errors and User Cancellation
  
  03:40
- When you're developing an application you'll want to provide a way for users to contact you with support questions or feedback.
