Ios 使用UIViewRepresentable在Swift中从背景状态返回后恢复动画？

在我的SwiftUI应用程序中，出于某些原因，我必须使用makeUIView函数在UIViewRepresentable中创建“sonar”视图并设置其动画。我只是有一个动画问题：当我将应用程序移动到背景并返回到它时，动画停止并且不会自动重新启动。我在网上搜索了几种解决方案，但我不确定如何在代码中解决这个问题

import UIKit
import SwiftUI
import Foundation

struct SonarView: View {
  
  var width: CGFloat
  var height: CGFloat
  
  struct TargetView: UIViewRepresentable {
    
    var width: CGFloat
    var height: CGFloat            
    
    func makeUIView(context: Context) -> some UIView {
      
      // Circle
      let circle = UIView()
      circle.frame = CGRect.init(x: 2, y: 2, width: width, height: height)
      circle.layer.cornerRadius = width / 2
      circle.layer.backgroundColor = UIColor(named: "PrimaryLight")?.cgColor
      circle.layer.borderWidth = 2
      circle.layer.borderColor = UIColor(named: "PrimaryDark")?.cgColor            
           
      return circle
    }
  
    func updateUIView(_ uiView: UIViewType, context: Context) {
        UIView.animate(withDuration: 1.75, delay: 0, options: [.repeat, .autoreverse], animations: {
            uiView.subviews[0].transform = CGAffineTransform(scaleX: 1.2, y: 1.2)
        }, completion: nil)
    }     
                
  }  
  
  var body: some View {
    TargetView(     
      width: self.width,
      height: self.height,
    )
  }
}

在SwiftUI部分，我实现了sonar视图，如下所示：

...
SonarView(width: geometry.size.height, height: geometry.size.height)
  .frame(width: geometry.size.height, height: geometry.size.height)
  .opacity(self.targetOpacity ? 1.0 : .zero)
  .onAppear {
     self.isNotNavigatingAnimationDelay = true
     withAnimation(Animation.easeOut(duration: 0.5).delay(0.5)) {
       self.targetOpacity = true
    }
  }
  .onDisappear {
    self.targetOpacity = false
    self.targetOffset = .zero
  }
...

使用

cabasicanitation

func updateUIView(_ uiView: UIViewType, context: Context) {
        let basicAnimation = CABasicAnimation(keyPath: "transform.scale")
        basicAnimation.toValue = 1.2
        basicAnimation.duration = 1.75
        basicAnimation.isRemovedOnCompletion = false
        basicAnimation.repeatCount = .greatestFiniteMagnitude
        basicAnimation.autoreverses = true
        uiView.subviews[0].layer.add(basicAnimation, forKey: "transformanimation")
    }

谢谢它在makeUIView函数中工作得很好
