ViewAnimator is a library for building complex iOS UIView animations in an easy way. It provides one line animations for any view included the ones which contain other views like UITableView and UICollectionView with its cells or UIStackView with its arrangedSubviews.
SVG animations inspired by Luke Zhao's project Hero
UI created by Messaki, make sure to check out his profile.
ViewAnimator is available through CocoaPods. To install it, simply add the following line to your Podfile:
pod "ViewAnimator"Drop the swift files inside of ViewAnimator/Classes into your project.
ViewAnimator provides a set of UIView extensions to easily add custom animations to your views.
Direction provides the axis where the animation should take place and it's movement direction.
let animation = AnimationType.from(direction: .top, offset: 30.0)
view.animate(animations: [animation])Zoom in and Zoom out animation support.
let animation = AnimationType.zoom(scale: 0.5)
view.animate(animations: [animation])UITableView, UICollectionView and UIStackView conform to Animatable protocol. This lets us animate their visible subviews or cells with only one function.
func animateViews(animations: [Animation],
initialAlpha: CGFloat,
finalAlpha: CGFloat,
delay: Double,
duration: TimeInterval,
animationInterval: TimeInterval,
completion: CompletionBlock?)All of this parameters have default values except AnimationType. They can be modified globaly with ViewAnimatorConfig static properties.
If you are just trying to see how ViewAnimator can fit in your project and don't want to spend any time reading at docs or testing the animations just call view.animateRandom() on your UIViewController and you'll get a set of random animations for your subviews. UITableViews/UICollectionViews and UIStackViews will have their visible views animated individually with the same animation but with a delay between each view.
view.animateRandom()You can combine conformances of Animation to apply multiple transforms on your animation block.
let fromAnimation = AnimationType.from(direction: .right, offset: 30.0)
let zoomAnimation = AnimationType.zoom(scale: 0.2)
let rotateAnimation = AnimationType.rotate(angle: CGFloat.pi/6)
collectionView.animateViews(animations: [zoomAnimation, rotateAnimation], duration: 0.5)
tableView.animateViews(animations: [fromAnimation, zoomAnimation], duration: 0.5)Animation protocol provides you the posibility of expanding the animations supported by ViewAnimator with exception of the animateRandom function.
public protocol Animation {
var initialTransform: CGAffineTransform { get }
}- Create protocol for the animations.
- Support combining animations.
- Add Carthage support.
- Add SPM support.
- Add more use cases to the example app.
- Add autohide functionality.
- Swift 4.0
- Xcode 9.0+
- iOS 9.0+
Feel free to collaborate with ideas 💭, issues
If you use ViewAnimator in your app I'd love to hear about it and feature your animation here!
