Wrap up

This was a deliberately short technique project taking an existing app and making it better. I hope you didn't get too bored, and hope even more that some of the new material sunk in because we covered UIBarButtonItem and UIActivityViewController.

As you’ve seen, it really is trivial to add social media to your apps, and it can make a huge difference to helping spread the word about your work once your apps are on the App Store. All being well, this project has also shown you how easy it is to go back to previous projects and improve them with only a little extra effort.

Review what you learned

Anyone can sit through a tutorial, but it takes actual work to remember what was taught. It’s my job to make sure you take as much from these tutorials as possible, so I’ve prepared a short review to help you check your learning.

Click here to review what you learned in project 3.

Challenge

One of the best ways to learn is to write your own code as often as possible, so here are three ways you can apply your knowledge to make sure you fully understand what’s going on:

  1. Try adding the image name to the list of items that are shared. The activityItems parameter is an array, so you can add strings and other things freely. Note: Facebook won’t let you share text, but most other share options will.
  2. Go back to project 1 and add a bar button item to the main view controller that recommends the app to other people.
  3. Go back to project 2 and add a bar button item that shows their score when tapped.

Share your success!

One of the most effective motivators of success is sharing your progress with other people – when you tell folks what you're doing and what you've learned, it encourages you to come back for more, which in turn will help you reach your app development goals faster.

So, now that you've done all the hard work it's time to share your success: tell folks that you've completed this project, either by clicking the button below to start composing a tweet, or by writing your own message from scratch. This will definitely encourage you to keep learning, but it will also help other folks discover my work – thank you!
