问题描述
这是在iOS 9中。我无法设置SKView的背景颜色，它始终以默认的灰色呈现。可以解决这个问题吗？
This is with iOS 9. I am unable to set the background color of an SKView, it always renders with the default grey. Is there a way around this?
let frame = CGRect(x: 0, y: 0, width: 200, height: 100)
let spriteView = SKView(frame: frame)
spriteView.backgroundColor = .blueColor()
self.view.addSubview(spriteView)
运行上述代码时，SKView是灰色而不是蓝色。我真正想要做的是设置 allowsTransparency = true ，但是如果我不能将背景色更改为<$ c $，我将无法正常工作c> clearColor 。
When the above code is run the SKView is grey instead of blue. What I really want to be able to do is set allowsTransparency = true but I can't get that to work if I can't change the background color to clearColor.
还有其他人遇到吗？有任何解决方法吗？
Anyone else running into this? Any workarounds?
更新
即使有@Danilo的建议，它仍然会显示如灰色：
Even with @Danilo's suggestion, this still displays as grey:
let frame = CGRect(x: 0, y: 0, width: 200, height: 100)
let spriteView = SKView(frame: frame)
spriteView.backgroundColor = .clearColor()
spriteView.allowsTransparency = true
spriteView.opaque = false
更新
显然设置<$ c $ SKView的c> backgroundColor 无效，但如果将其设置为任何值，则 allowsTransparency = true 不起作用。
Apparently setting the backgroundColor of an SKView has not effect, but if you do set it to anything then allowsTransparency = true doesn't work.
推荐答案
除了添加 SKView ，我们还需要 SKView 将显示的> SKScene ；然后，我们调整/更改 SKScene 的 backgroundColor 。场景中会依次添加一个节点。
In addition to adding a SKView, we need a SKScene that is to be presented by the SKView; we then adjust/change the backgroundColor of the SKScene. A node, in turn, will be added by the scene.
例如：
//create a SKView, which takes up the same frame as our view
let spriteView = SKView(frame: self.view.bounds)
//adding spriteView as a child view of our view
self.view.addSubview(spriteView)
//Here, we create a scene, which is the root object of
//the graph
let scene = SKScene(size: spriteView.frame.size)
scene.backgroundColor = .orangeColor()
//As said, we present the scene with our SKView
spriteView.presentScene(scene)
//Here, we create a node, which will be added by our scene
//This node takes up a size that you originally created and has the
//background color set to blue
let nodeFrame = CGRect(x: 0, y: 0, width: 200, height: 100)
let node = SKSpriteNode(color: .blueColor(), size: nodeFrame.size)
//The following just serves to show how we can adjust the node's
//position; I will leave that to you
node.position = CGPointMake(scene.frame.size.width - 200, scene.frame.size.height - 100)
//Finally, we add the node to our scene
scene.addChild(node)
