【问题描述】：

这是我的视图控制器

 class ViewController: UIViewController 

        var index = 0
        @IBOutlet weak var lottieView: UIView!
        fileprivate let lottieTouchIdAnimationName = "01_touchId_validation"
        fileprivate let lottieFaceIdAnimationName = "01_faceId_validation"
         @IBOutlet weak var label: UILabel!
        var onBoardingCompletionBlock: ((Bool, Bool?) -> Void)?
        var authenticationResponse: Bool!


        override func viewDidLoad() 
            super.viewDidLoad()

            setupView()
        


        func setupView() 

            var animationName = ""
            switch index 
            case 0:
                animationName = lottieFaceIdAnimationName
                label.text = "anim 0"
            default:
                animationName = lottieTouchIdAnimationName
                label.text = "anim 1"
            

            _ = LottieView(in: lottieView,
                           bundle: Bundle.main,
                           name: animationName,
                           velocity: 1.0,
                           loop: false) [unowned self] _ in
                            self.animationEnded()
            
        
        func animationEnded() 
            if let onBoardingCompletionBlock = onBoardingCompletionBlock 
                onBoardingCompletionBlock(true, self.authenticationResponse)
                dismiss(animated: true, completion: nil)
             else

我已经安装了 pod，并且资产都在 XCAssets 中可用

【问题讨论】：

在哪里添加LOTAnimationView???

lottie 视图未正确初始化。

【参考方案1】：

试试这个：

class HmePaymentStatusVC: UIViewController 
    var animationView = LOTAnimationView(name: "lottie_animation_file")

    override func viewDidLoad() 
        super.viewDidLoad()
        animate()
    

    func animate() 
        animationView.frame = view.bounds
        animationView.contentMode = .scaleAspectFit
        animationView.animationSpeed = 0.5
        self.view.addSubview(animationView)
        animView.play()
