Demo App for SwiftMN Animations talk. September 2017

About the project

This App is a simple tableView with a list of Futurama characters. When you tap on one of the cells a new viewController is presented with details about that character. The commits in this repo are structured to walk you through building up animations to transition from the MainViewController to DetailViewController and back.

Working through the process

Initial Project

Checkout the base app to familiarize yourself with the code

git checkout 442ce5de2b349d8c650c89895e2d816d21e7f5aa

Animate from cell to detail view

Using UIViewControllerTransitioningDelegate and a custom UIViewControllerAnimatedTransitioning object, we add an animation from the selected cell to the detail view.

Animate from detail view back to cell

Expanding on the TransitionAnimator object that we created, we make our animation reversible for when the detail view is dismissed.

Add blur effect

To make the transition a little smoother we add a blur effect to the tableView, and animate it in and out along with the transition.

Animate description

The transition is pretty smooth, but that desctiption popping in is pretty jarring. Let's try to make that smooth, too.

Animate description independently of other views using keyframes

The description is animating in, but if you look closely, it moves a bit as it fades in. Using keyframes we can animate the view in and then fade the description in. Likewise, we can fade the description out before animating the view back to the cell.
