The word “animation” is derived from a Latin word that means “the act of bringing to life.” In your applications, animations can smoothly bring interface elements onscreen or into focus, they can draw the user’s attention to an actionable item, and they can give clear indications of how your app is responding to the user’s actions.
In this chapter, you will update the Mandala application and use some animation techniques to bring the ImageSelector to life. iOS makes these animations simple, so in no time your app will have a polished, professional look and feel.
Before updating Mandala, though, let’s take a look at what can be animated by looking at the documentation. To open the documentation, open Xcode’s Help menu and select Developer Documentation. This will open the documentation in a new window.
With the documentation open, use the search bar at the top to search for UIView. In the search results, click UIView to open the class reference, then scroll down to the section titled Animations. The documentation gives some information about animations and lists the properties on UIView that can be animated (Figure 19.1).
