如何从SKSpriteNode获取UIImage

Question

我从SKSpriteNode获取UIImage对象时遇到了问题，即我可以得到它，但在更改SKSpriteNode的属性如blendMode，colorBlendFactor和color之后，纹理属性保持不变。这是一个例子：

let sprite = SKSpriteNode(imageNamed: "fishka")
sprite.blendMode = .alpha
sprite.colorBlendFactor = 1
sprite.color = UIColor.red
let fishka = UIImage(cgImage: (sprite.texture?.cgImage())!)

这就是我得到的：

result after converting to UIImage (fishka)和image in SKSpriteNode object (sprite)

请问，如何在SKSpriteNode中获取带图片的UIImage对象？

谢谢

UPDATE

这是另一个使用CGContext获取所需结果的代码

let img = UIImage(named: "fishka")!
let rect = CGRect(x: 0, y: 0, width: img.size.width, height: img.size.height)
UIGraphicsBeginImageContext(rect.size)
let ctx = UIGraphicsGetCurrentContext()
img.draw(in: rect)
ctx?.setFillColor(UIColor.red.cgColor)
ctx?.setAlpha(1)
ctx?.setBlendMode(.sourceAtop)
ctx?.fill(rect)
let image = UIGraphicsGetImageFromCurrentImageContext()

现在图像看起来像this

调整ctx？.setAlpha（）不是解决方案，因为我想要一个明亮的红色保持体积view

还有其他解决方案吗？

使用SKView.texture(from:SKNode)来实现你想要的。

let sprite = SKSpriteNode(imageNamed: "fishka")
sprite.blendMode = .alpha
sprite.colorBlendFactor = 1

sprite.color = UIColor.red
var fishka = UIImage?
autoreleasepool{
    fishka = scene!.view!.texture(from:sprite)
}
