By doing this, you have learned how to make table views with static cells display data, as well as how to create a custom map image, which you can now implement in your own apps.

Congratulations! All the screens in your app now display data. However, if you look at the Restaurant Detail screen, there are no ratings, reviews, or photos for the restaurant, and no way to add them. You will implement this starting from the next chapter, where you'll create a custom control...
