They’ve all written a children’s book…and so will you.

Overall Requirements

In this assignment, you will create an interactive children’s book that is constructed using UIPageViewController in Swift. You will have to write a hilarious, heartwarming and/or educational tale of at least 6 pages. Feel free to add additional pages if your story demands it.

• “Home Page” that represents the beginning of the book

• “Settings Page” for “Read to Me” options
  • View controller written in Objective-C
• “About the Author” page protected by Parental Gate.
  • Parental gate will use custom drawing for validation
  • Use an external .nib file for this UIViewController.
• Each book page should have a “Tap-to-play” button. When tapped, the read-to-me function should start.
  • Automatically play on each page (if option is selected in settings)
• Store user preferences for “read-to-me” functionality.
  • If enabled, the pages should automatically read when the page is loaded.
• Store currently reading page so that book opens to the correct page when the application comes to the foreground.

Home Page

• The Home page is the launch point for the book. This page should have the name of the book and the author’s name.
• Include a button to navigate to the the Settings page.
• Include a button to navigate to the About the Author page.

You use a UINavigationController to handle the navigation from the home screen to the Settings and Author scenes. However, if you are using it to navigate to the book pages, you should hide the navigation bar so that it is not visible on the book pages.

About the Author Page

• The About the Author page should be protected by a parental gate.
• See parental Gate explained by Apple.
• A parental gate is described by the App Store Guidelines below:

24. Kids Apps
	•	24.3- Apps primarily intended for use by kids under 13 must get parental permission or use a parental gate before allowing the user to link out of the app or engage in commerce
This requires gating when linking out of the app or engaging in commerce such as selling in-app items.

• You can implement the parental gate anyway you wish. However it should incorporate finger drawing recognition.

See the session slides for examples

• Use a custom ErrorType and a validation method that uses the Swift do-try-throw model of error handling to test your parental gate.

• Use an external .nib file to create the UIViewController for the parental gate.

hen you add a file, make sure to check to create an nib file for the UIViewController subclass. You will have to programmatically navigate to this view controller from the Home screen.”

Settings Page

• The Settings page should hold the following Read to Me options:
• Automatically play on each page
• Tap-to-play
• You can use whatever UIControl (or custom control) you want to make the selection.
• The application should store the prefereces using NSUserDefaults and honor the Read to Me options when pages are turned
• The entire ViewController should be implemented in Objective-C

Story Pages

• You can choose to use either gesture or buttons (or both) to advance the pages.
• Every story content page must implement:
• “Read to Me” functionality on each page (triggered by a button or automatically based on preferences)
• Words should highlight as they are read (using a method of your choice)
• Each page should have pictures and text.
• You must use UIDynamics for at least one on-screen element in your book.
• You must use UIGestureRecognizers for at least one on-screen element in your book.
• You must use UIViewPropertyAnimator for at least one on-screen element in your book.
• You should be able to tap to hear sound effects on at least one page.
• Each page should have a button to return to home page. This button should be on the page, not on a navigation bar.

Additional Functionality

• Create a bookmark by storing the current page in NSUserDefaults. When the apps is relaunched, you should be taken to the current page. Pay attention to the different multi-tasking states to achieve the correct effect. This will be tested.
• The story must be more entertaining than “Shaq and Beanstalk”.
• You must create an App Preview

Application Design

• You can reuse the same view controller for different pages or use completely unique view controllers for each page. The implementation details are up to you.
• Observe best practices using MVC pattern.
• Create a singleton for your sound effects.
• Observe best Swift practices for declaring variables and constants.
• Where appropriate separate logic from presentation (i.e. do not overload your UIViewControllers).
• Comment your code using HeaderDoc syntax.
• Use Swift’s // MARK: statement for code organization
• Check out this style guide for inspiration. You do not have to follow it exactly, but use it to guide development of your own style.
• Use camel case (e.g. mySoundEffect, imagePath) to declare variable names.

Grading

The application should compile with no errors or warnings and perform all described behaviors. If the app does not compile you will receive a 0. Feel free to explore additional enhancements to improve the appearance or functionality of the application.
