Features of the app:
- The move buttons are handled by a single function that moves the bunny in the correct direction based on the button's tag.
- The move amount depends on the scale of the bunny, and uses a spring animation.
- The animation is handled by a single
animateTransform()function. - The responses to the entered chat messages come from a random selection of strings.
- The chat keyboard is customized to use the Send button, and is automatically displayed when the screen is shown.
The login screen wasn't added, as that seemed like a copy-and-paste error from the Facebook exercise above.
