推荐答案

您可以实现自己的使用Core动画的自定义视图 CALayer 以存储图像。当您设置图层的 contents 属性时，图片将自动平滑地从旧图片动画到新图片。

You could implement your own custom view that uses a Core Animation CALayer to store the image. When you set the contents property of the layer, the image will automatically smoothly animate from the old image to the new one.
