ios - 如何在不使用 tableView.reloadData() 的情况下访问 Swift 中闭包外的数据？

Question

我正在使用 UIViewController 并从 firebaseUI 获取图像并希望为其设置动画。但是我不知道该怎么做。请帮帮我。不使用tableViewController如何实现呢？

func getImage()
        {
           var Images = [String]()
            Images = ModelManager.getInstance().getImages(imageName)


            let storage = Storage.storage().reference()
            let storageRef = storage.child("images")

            for x in Images{


                let path = storageRef.child("\(x).jpg")         
                path.getData(maxSize: 1 * 1024 * 1024) { (data, error) in
                    if let error = error{
                        print(error.localizedDescription)
                        print(error)
                        return
                    }
                    else{
                            self.imageList += [UIImage(data: data!)!]
                    }
                }

            }


            myImageView.animationImages = imageList
            myImageView.animationDuration = 2
            myImageView.startAnimating()
        }

}

您可以通过以下方式实现您的要求。

 func getImage()
        {
            var Images = [String]()
            Images = ModelManager.getInstance().getImages(imageName)

            let storage = Storage.storage().reference()
            let storageRef = storage.child("images")

            for x in Images{
                let path = storageRef.child("\(x).jpg")
                path.getData(maxSize: 1 * 1024 * 1024) { (data, error) in
                    if let error = error{
                        print(error.localizedDescription)
                        print(error)
                        return
                    }else{
                        self.imageList += [UIImage(data: data!)!]
                    }

                    if x = Images.last {
                        myImageView.animationImages = imageList
                        myImageView.animationDuration = 2
                        myImageView.startAnimating()
                    }
                }
            }
        }
