The Map screen now displays your custom annotations, and tapping one displays a callout bubble showing restaurant details. The callout button doesn't work yet, though. To go to the Restaurant Detail screen from the callout button, you will add a storyboard reference to your project. For your convenience, inside the resources folder that you downloaded earlier, you'll find the completed storyboards named RestaurantDetail.Storyboard, PhotoFilter.Storyboard, and ReviewForm.Storyboard. You will link the storyboard reference you added to RestaurantDetail.storyboard instead of using the Restaurant Detail screen you made earlier.
