После анимации CAReplicatorLayer в `subview``vc` переключение `vc` вызывает странную проблему
CAReplicator не сохранил состояние после переключения vc:
Dots из CAReplicator не сохранил своего масштаба после vc переключиться обратно.
Как видите, круговая анимация создается CAReplicator,
после основной vc переключиться на другое vc, затем переключитесь назад, Circle"s dots стать очень маленьким. ведьма установлена в начальном.
Мой код ниже:
В основном vc:
func initUI() {
let lml_frame = CGRect.init(x: 0, y: 64, width: self.view.bounds.size.width, height: 400)
lml_digtal_view = LMLDigitalDazzleAnimationView.init(frame: lml_frame)
self.view.addSubview(lml_digtal_view!)
}
в LMLDigitalDazzleAnimationView:
import Foundation
import UIKit
class LMLDigitalDazzleAnimationView: UIView {
/*
// Only override draw() if you perform custom drawing.
// An empty implementation adversely affects performance during animation.
override func draw(_ rect: CGRect) {
// Drawing code

}
}
Мой код не очень хороший, вы можете посоветовать мне, как лучше инкапсулировать класс анимации.

Решение
После большого внимания я решаю свою проблему:
delay(delay: duration) {
let turn_key_path = "transform.rotation"
let turn_ani = CABasicAnimation.init(keyPath: turn_key_path)
turn_ani.isRemovedOnCompletion = false
turn_ani.fillMode = kCAFillModeForwards
turn_ani.toValue = M_PI*2
turn_ani.duration = 2.0
turn_ani.repeatCount = 2
r.add(turn_ani, forKey: turn_key_path)
dot.transform = CATransform3DMakeScale(1, 1, 1) // add this line solve my issue.
}
