In the animate(sender: ) method, if you start to type UIView.animate, the Xcode autocomplete will give you a few options. To do that, we have to request the help of our resident Animation API that the good folks at Apple have been so kind as to provide for us. Once you’ve done that, let’s start animating a basic property like appearance. Make sure it is an Action of type UIButton. Next, connect the Animate button below the viewDidLoad() method. The first thing we want to connect is our UIView, and the easiest way to connect it would be from the Document Outline on the left.įrom there, you can either Option + drag or right-click drag to the DarkViewController.swift file just above the viewDidLoad method. The one that looks like two overlapping circles. Open Main.storyboard, select the Dark View Controller and click on the Assistant Editor in the top right section of Xcode. The first thing we have to do is to connect our views to the Swift file. Auto Layout, however, won’t be a problem if you’re planning to remove the view from its superview or if you also create an animation to return the view back to its origin. Note: When animating position and size properties, as soon as the animation completes, Auto Layout will recalculate the constraints and the view will snap back to its original position. This comes from the CoreGraphics API, which will not be covered in this tutorial. Transformation consists of rotation, scale, and translation.

Appearance consists of the background color and alpha of a view.

Changing these properties will have obvious conflicts with autolayout.

Position & Size consists of the bounds, frame and centre of a view.

There are three categories of animatable view properties: Animating View Propertiesīefore we get down to the animating business, let’s cover a bit of theory. We will be using this ViewController to demonstrate animating view properties. Run the project to see how the "awesome" design looks in action. Open Main.storyboard where you’ll see DarkViewController that is composed of a UIView centered in the view controller and an Animate button way down at the bottom with enough space to let the UIView do its thing. You should find a file structure that looks like this: Once you’ve downloaded or cloned it, go ahead and open the project file.

Now that we have what we’ll need, let’s get to work. If you don’t have any of these, go ahead and get them now. Basic knowledge of the Swift 4 language and Auto Layout.
