Advanced Swift 2 Application Development (Video 20)

This video tutorial explains how to display data on a map view using a bespoke MK annotation and an NSS results controller. It covers updating the core data model to include latitude and longitude, implementing a dream annotation class, and using a fetch results controller to present data on the map. The tutorial provides a step-by-step guide to setting up the necessary components and demonstrates how to visualize data on a map view.

What is the primary purpose of creating a bespoke MK annotation?

• To change the map's background color

• To display custom data points on the map

• To manage user input on the map

• To enhance map performance

What is the first step in preparing data for map display?

• Creating a new storyboard

• Setting latitude and longitude for each data item

• Adding a new view controller

• Implementing a new protocol

Why is it necessary to increment the model version in Core Data?

• To add new attributes to an entity

• To change the app's theme

• To improve app performance

• To delete old data

What is the role of the Dream Annotation class?

• To store user preferences

• To represent data points on the map

• To manage network requests

• To handle user authentication

Which protocol must the Dream Annotation class implement?

• NSCoding

• MKAnnotation

• UITableViewDelegate

• NSCopying

What is the purpose of using NSFetchedResultsController in this context?

• To update the app's UI theme

• To handle app notifications

• To fetch and display data on the map

• To manage user sessions

What is checked after fetching data with NSFetchedResultsController?

• If the network connection is stable

• If the user is logged in

• If the sections count is greater than zero

• If the app is running in the background
