动画是否播放，取决于链接动画的animationRepeatCount

Question

此问题与链接动画有关，如果您需要更多代码，请告诉我。我是iOS的新手，我一直在寻找一种解决方案，找到了一个帖子，但答案是他们不知道确切的问题是什么。

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]

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")
        }

    }
口述== 0的方法的第一个块，该动画效果很好，但是当到达口述== 1的动画不播放时，它将设置图像，但不播放动画。我一直在环顾四周，我试图在主线程和其他一些东西上运行它。

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，否则它将不会播放；如果我将此动画设置为除0以外的任何值，则上面的动画会播放，但此动画不会播放。在这种方法中，我将动画重复计数设置为16，然后上面的动画起作用了，但是这个效果没有。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还是很陌生，有些事情我只是不对。

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，它不会让我，因为它超出了字符数限制，但是会发布所有动画并说明流程

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位置。

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末尾转到SpeechSynthesizer方法，其中spoken == 0然后执行上面发布的handleSend()方法，然后回到上面的口述== 1的SpeechSynthesizer方法

如果您需要更多信息，请告诉我
