是否播放动画取决于链式动画的animationRepeatCount [英] Animation playing or not depending on animationRepeatCount for chained animations
问题描述
我对iOS完全陌生，我正在开发具有许多帧动画的应用程序。一切都进行得很好，直到我尝试使用下面发布的方法制作最终动画为止。该方法是分配给内置文本到语音合成器的委托
I am totally new to iOS and I am working on an application that has many frame animations. Everything is going well until I try to do my final animation in a method that I am posting below. The method is a delegate assigned to the Built in Text to Speech synthesizer
func speechSynthesizer(_ synthesizer: AVSpeechSynthesizer, didFinish utterance: AVSpeechUtterance) {
if spoken == 0{
spoken += 1
print("speaking finished")
self.ImageView.stopAnimating()
self.ImageView.image = self.circleImages.last
self.ImageView.animationImages = self.circleImages
self.ImageView.animationDuration = 1.5
self.ImageView.animationRepeatCount = 0
self.ImageView.startAnimating()
do{
try self.recordAndRecognizeSpeech()
}catch let error{
print(error)
}
}else if spoken == 1{
//animation 1
spoken += 1
//animation 1
self.ImageView.image = self.comingOutImages.first
self.ImageView.animationImages = self.comingOutImages
self.ImageView.animationDuration = 6.0
self.ImageView.animationRepeatCount = 1
self.ImageView.startAnimating()
print(String(self.comingOutImages.count) + " #of images")
print("should have animated go in" + String(spoken))
}else{
print("done")
}
}
该方法的第一个方块，其中口语== 0，该动画效果很好，但是当到达该区域时，口语== 1，则动画无法播放设置图像，但不播放动画。我一直在四处寻找，我试图在主线程和其他东西上运行它。
The firs block of the method where spoken == 0, that animation works fine, but when it gets to the block where spoken == 1 that animation does not play it sets the image but it does not play the animation. Ive been looking around forever, I tried to run it on the main thread and a bunch of other things.
编辑：
我有这个方法，它是在上面的动画之前的动画，除非将animationRepeatCount设置为0，否则它将不播放；如果我将此动画设置为除0之外的任何值，则上面的动画将播放但那么该动画就不会播放。在这种方法中，我将动画重复计数设置为16，然后上述动画有效，但该动画无效。我想将此动画设置为repeatCount 0，并在完成语音处理后将上面的动画设置为repeatCount1。我对iOS非常陌生，有些事情我只是不对。
I have this method which is the animation right before the animation above that will not play unless set animationRepeatCount to 0, and if I set this animation to anything but 0 then the animation above plays but then this animation doesn't play. In this method I have animation repeat count to 16 and then the above animation works but this one doesn't. I would like to have this animation set to repeatCount 0 and when speech is done to fire the one above to repeatCount 1. Im very new to iOS and there is something I am just not getting right.
func handleSend(){
if Thread.isMainThread{
print("send on main thread")
}else{
print("send not on main thread")
}
do{
try AVAudioSession.sharedInstance().setCategory(.playback, mode: .default)
try AVAudioSession.sharedInstance().setActive(true)
}catch{}
//UIView.animate(withDuration: 4.0, animations: {
//animation 2
print("second animation")
self.imageView.stopAnimating()
self.imageView.image = self.talkingImages.last
self.imageView.animationImages = self.talkingImages
self.imageView.animationDuration = 0.25
self.imageView.animationRepeatCount = 16
self.imageView.startAnimating()
print("should have animated")
//})
let utterance = AVSpeechUtterance(string: self.finalString)
//utterance.voice = AVSpeechSynthesisVoice(language: "en-GB")
//utterance.rate = 0.1
self.synthesizer.speak(utterance)
}
EDIT2：我发布整个viewController只是为了参考，因为它超出了字符数限制，它不允许我这样做，但是我却发布了所有动画并解释了流程
这是用于触摸图像视图的touchended覆盖方法，也是第一个动画开始的地方。
this is the touchended override method for touching the image view, it is also where the first animation starts.
override func touchesEnded(_ touches: Set<UITouch>, with event: UIEvent?) {
timesRubbed += 1
if timesRubbed == 1{
player?.stop()
//Toast(text: keepRubbing).show()
self.view.makeToast(keepRubbing, duration: 3.0, position: .top)
}
if timesRubbed == 2{
player?.stop()
//Toast(text: keepAgain).show()
self.view.makeToast(keepAgain, duration: 3.0, position: .top)
}
if timesRubbed == 3{
player?.stop()
timesRubbed += 1
playSoundComeOut()
CATransaction.begin()
CATransaction.setCompletionBlock {
print("after animation 1")
DispatchQueue.main.async {
CATransaction.begin()
CATransaction.setCompletionBlock{
print("after circle animation")
//UIView.animate(withDuration: 3.0, animations: {
//animation 2
print("second animation")
//self.imageView.stopAnimating()
self.imageView.image = self.talkingImages.last
self.imageView.animationImages = self.talkingImages
self.imageView.animationDuration = 0.25
self.imageView.animationRepeatCount = 0
self.imageView.startAnimating()
print("should have animated")
//})
let utterance = AVSpeechUtterance(string: self.greeting)
//utterance.voice = AVSpeechSynthesisVoice(language: "en-GB")
//utterance.rate = 0.1
self.synthesizer.speak(utterance)
//CATransaction.commit()
}
//UIView.animate(withDuration: 3.0, animations: {
//animation 2
print("second animation")
self.imageView.stopAnimating()
self.imageView.image = self.circleImages.last
self.imageView.animationImages = self.circleImages
self.imageView.animationDuration = 1.5
self.imageView.animationRepeatCount = 2
self.imageView.startAnimating()
print("should have animated")
//})
CATransaction.commit()
}
}
//UIView.animate(withDuration: 6.0, animations: {
//animation 1
if self.imageView.isFocused{
print("imageview is focused")
}else{
print("not focused")
}
self.imageView.image = self.comingOutImages.last
self.imageView.animationImages = self.comingOutImages
self.imageView.animationDuration = 6.0
self.imageView.animationRepeatCount = 1
self.imageView.startAnimating()
// })
CATransaction.commit() }
}
然后在该动画序列的结尾转到SpeechSynthesizer方法，其中 spoken == 0 然后执行上面发布的 handleSend（）方法，然后执行返回到上面的语音合成器方法，其中语音== 1
then at the end of that animation sequence it goes to the speechSynthesizer method where spoken == 0 then it does the handleSend() method posted above and then it goes back to the speechSynthesizer method above where spoken == 1

推荐答案
我结束了修改了最后一个动画的效果，并且效果很好
I ended up doing this for the last animation and it worked
self.imageView.stopAnimating()
self.imageView.image = self.goingInImages.last
self.imageView.layer.removeAllAnimations()
let animation = CAKeyframeAnimation(keyPath: #keyPath(CALayer.contents))
animation.values = self.goingInImages.map {$0.cgImage!}
//animation.keyTimes = [0.0, 0.25, 0.5, 0.75, 1.0]
animation.calculationMode = .discrete
animation.duration = 6.0
animation.repeatCount = 1
self.imageView.layer.add(animation, forKey: nil)
