Couldn't find onAnimationRepeat listener?

[ArtemMikhaylov]

Is there some kind of onAnimationRepeat listener like in lottie android?

When animation is in a loop mode, every moment it starts over we have onAnimationRepeat called in lottie android. And I couldn't find such possibility in lottie-ios.

It would be nice to have one!

We don't currently provide callbacks for this type of thing. One key obstacle is that this wouldn't work with the new default Core Animation rendering engine, where Lottie itself isn't running code every frame so wouldn't know when to call the closure.

One way to accomplish this functionality in user code could be:

func playAnimationOnce() {
  animationView.play(loopMode: .playOnce, completion: {
    // perform code now that the animation has finished its loop
    self.playAnimationOnce() // continue looping after the animation completes
  })
}
