Animation completion will not work under some circumstances

[iaomw]

I need to remove all the animations on some layer under specific condition. But after I did something like this, it become impossible to add animation any more. How could I cancel all animation without hurt it?

self.spriteLayer.removeAllAnimations()

can you please paste in a chunk of code of how you add the animations and how you remove them so I can try to reproduce the problem?

Sorry, not the same as I expected before. It something like that below. I will change the title. While I am touching too fast, the completion block will not work.

func transformToTouching() { //Response to touching event

    self.setHighlighted(true, animated: true)

    self.animationQueue.removeAll(keepCapacity: true)

    EAAnimationDelayed.animations.map {

        $0.cancelAnimationChain()
    }

    self.spriteLayer.removeAllAnimations()

    self.chainAnimation({ () -> Void in

        self.spriteLayer.fillColor = ...
        self.spriteLayer.path = ...

    }, duration: 0.3)
}

typealias AnimationBlock = () -> Void
typealias AnimationPiece = (animation:AnimationBlock, duration: NSTimeInterval)

var animating:Bool = false
var animationQueue = [AnimationPiece]()

func chainAnimation(animation: AnimationBlock, duration: NSTimeInterval) {

    self.animationQueue.append((animation:animation, duration: duration))

    self.feedAnimation()
}

func feedAnimation() {

    if self.animating {

        return
    }

    if let some = self.animationQueue.first {

        self.animationQueue.removeAtIndex(0)

        self.animating = true

        UIView.animateWithDuration(some.duration, delay: 0.0, options: UIViewAnimationOptions.CurveEaseInOut, animations: some.animation, completion: { (done: Bool) -> Void in // Not work while too fast

            self.animating = false

            self.feedAnimation()
        })

    } else {

        return
    } //
}

what I see at first sight is that you never actually use the EasyAnimation API to create chains - animateAndChainWithDuration(...). You can cancel only custom EA chains, since the "normal" animations you create with the UIKit API aren't cancelable (but not a bad idea to think if it's possible to do that). Review again the example in the README: https://github.com/icanzilb/EasyAnimation#cancel-chain-animations

I really want to use your chain, but it doesn't work out while I chain them from different place. #9
Oops, as the block, we can comment it, it doesn't matter for the phenomenon. 😂

EAAnimationDelayed.animations.map {

        $0.cancelAnimationChain()
}
