UImage加载整个SKTextureAtlas而不仅仅是SKTexture

Question

我需要带'trueName'的纹理加载到我的myImageViewOutlet.image中。我得到的结果是整个图集渲染到它。我的代码如下

let myTextureAtlas = SKTextureAtlas.init(named: "myGameTextures") 

// let texture = myTextureAtlas.textureNamed(trueName) // will render the entire atlas, instead of just the texture by trueName 

let texture = myTextureAtlas.textureNamed(trueName+”bad name“) // will produce the placeholder image by sprite kit by itself just fine, but it's not the one I want obviously 

let image = texture.CGImage() 

let newImage = UIImage(CGImage: image, scale: 1.0, orientation: UIImageOrientation.Up) 
//  let newImage = UIImage(CGImage: image) // .. the straight forward way 

myImageViewOutlet.image = newImage 

Answer 1

我不甘心image.CGImage（）不从SKTextureAtlas支持纹理，读一本类似的帖子SKTextures from SKTextureAtlas does not support mipmapping后。

一种方法是，以形成从SKView.textureFromNode一个SKTexture（_节点：SKNode）

let textureToRender = myOffscreenView.textureFromNode(nodeToRender) 

let newImage = UIImage(CGImage: textureToRender.CGImage())
