Add another 'Animation' Library



ver 2.0

NB! Breaking changes in 2.0 - due to a lot of requests EasyAnimation does NOT automatically install itself when imported. You need to enable it by calling EasyAnimation.enable() somewhere in your code (AppDelegate is a good idea).

The library doesn't use any private APIs - apps using it should be fine for release on the App Store.

UIView.animateWithDuration:animations: is really easy to use and you're so familiar with its syntax that you often want it to do just a bit more for you automatically. But it doesn't and you need to import Bloated.framework by Beginner Ninja Coder in order to make a bit more advanced animations than what animateWithDuration:animations: allows you to.

EasyAnimation extends what UIKit offers in terms of animations and makes your life much easier because you can do much more without learning some perky new syntax.

In version 2.0 and higher to enable all EasyAnimation features you need to run once this code - AppDelegate is a good place since it'll enable EasyAnimation as soon as your app starts.


In your other classes you don't need to import EasyAnimation or do anything else. Once you call enable() afterwards you use the normal UIKit APIs like usual.

Easy Layer Animations

EasyAnimation allows you to animate your layers straight from animate(duration:animations:...). No more CABasicAnimation code for you. Just adjust the properties of your layers from within the animations block and EasyAnimation will take care of the rest: CoreAnimation (before) let anim = CABasicAnimation(keyPath: "position.x") anim.fromValue = 100.0 anim.toValue = 200.0 anim.duration = 2.0 view.layer.addAnimation(anim, forKey: nil) EasyAnimation (after) UIView.animate(duration: 2.0, animations: { self.view.layer.position.x = 200.0 })


(OK, this example actually works fine also without EasyAnimation but I still keep it here for illustrative purpose)

Or if you need to specify delay, animation options and/or animation curve:

CoreAnimation (before) let anim = CABasicAnimation(keyPath: "position.x") anim.fromValue = 100.0 anim.toValue = 200.0 anim.duration = 2.0 anim.fillMode = kCAFillModeBackwards anim.beginTime = CACurrentMediaTime() + 2.0 anim.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseOut) anim.repeatCount = Float.infinity anim.autoreverses = true view.layer.addAnimation(anim, forKey: nil) EasyAnimation (after) UIView.animate(duration: 2.0, delay: 2.0, options: [.repeat, .autoreverse, .curveEaseOut], animations: { self.view.layer.position.x += 200.0

    // let's add more animations 
    // to make it more interesting!
    self.view.layer.cornerRadius = 20.0
    self.view.layer.borderWidth = 5.0
}, completion: nil)


And if you want to execute a piece of code after the animation is completed - good luck setting up your animation delegate and writing the delegate methods.

With EasyAnimation you just put your code as the completion parameter value and EasyAnimation executes it for you when your animation completes.

Spring Layer Animations

One thing I really missed since iOS9 when using CoreAnimation and CABasicAnimation was that there was no easy way to create spring animations. Luckily a handy library called RBBAnimation provides an excellent implementation of spring animations for layers - I translated the code to Swift and included RBBSpringAnimation into EasyAnimation.

Easy Animation takes care to use the new in iOS9 spring animation class CASpringAnimation when your app runs on iOS9 or higher and falls back to RBBSpringAnimation when your app runs on iOS8.

Here's how the code to create a spring animation for the layer position, transform and corner radius looks like:

EasyAnimation UIView.animate(duration: 2.0, delay: 0.0, usingSpringWithDamping: 0.25, initialSpringVelocity: 0.0, options: [], animations: { self.view.layer.position.x += 200.0 self.view.layer.cornerRadius = 50.0 self.view.layer.transform = CATransform3DMakeScale(1.2, 1.2, 1.0) }, completion: nil)


Sam Davies collaborated on the spring animations code. Thanks a ton - I couldn't have figured this one on my own!

Chain Animations

animate(duration:animations:..) is really handy but chaining one animation after another is a major pain (especially if we are talking about more than 2 animations).

EasyAnimation allows you to use a method to just chain two or more animations together. Call animateAndChain(duration:delay:options:animations:completion:) and then chain to it more animations. Use animate(duration:animations...) or any other method to create chained animations.

EasyAnimation UIView.animateAndChain(duration: 1.0, delay: 0.0, options: [], animations: { self.view.center.y += 100 }, completion: nil).animate(duration: 1.0, animations: { self.view.center.x += 100 }).animate(duration: 1.0, animations: { self.view.center.y -= 100 }).animate(duration: 1.0, animations: { self.view.center.x -= 100 })


Yes - that works, give it a try in your project :]

This code will animate the view along a rectangular path - first downwards, then to the right, then up, then to the initial point where the animation started.

What a perfect oportunity to repeat the animation and make the animation run continuosly! Add options parameter to the last animate(duration:... in the chain and turn on the .repeat option.

This will make the whole chain (e.g. the 4 animations) repeat continuously.

If you want to pause between any two animations in the chain - just use the delay parameter and it will all just work.

Note: animateAndChain does not create a serial queue to which you could add animations at any time. You schedule your animations once with one call like the example above and it runs on its own, you can't add or remove animations to and from the sequence.

Cancel Chain Animations

If you have a repeating (or a normal) chain animation on screen you can cancel it at any time. Just grab hold of the animation object and call cancelAnimationChain on it any time you want.

let chain = UIView.animateAndChain(duration: 1.0, delay: 0.0, options: [], animations: { self.square.center.y += 100 }, completion: nil).animate(duration: 1.0, animations: { [... the rest of the animations in the chain]


If you want to do some cleanup after the animation chain is cancelled provide a block of code to the cancelAnimationChain method:

chain.cancelAnimationChain({ self.myView.center = initialPosition //etc. etc. })

The animation will not stop immediately but once it completes the current step of the chain it will stop and cancel all scheduled animations in this chain.
