我知道如果我有一个图像,我会在表面上放置纹理并实现这种效果,但我想知道我是否可以在球体表面上以某种方式动态添加文本.

任何的想法？

这有效：

let layer = CALayer()
    layer.frame = CGRectMake(0,100,100)
    layer.backgroundColor = UIColor.orangeColor().CGColor

    var textLayer = CATextLayer()
    textLayer.frame = layer.bounds
    textLayer.fontSize = layer.bounds.size.height
    textLayer.string = "Test"
    textLayer.alignmentMode = kCAAlignmentLeft
    textLayer.foregroundColor = UIColor.greenColor().CGColor
    textLayer.display()
    layer.addSublayer(textLayer)

    let Box = SCNBox(width: 10,height: 10,length: 10,chamferRadius: 0.5)
    let BoxNode = SCNNode(geometry: Box)
    Box.firstMaterial?.locksAmbientWithDiffuse = true
    BoxNode.position = position

    Box.firstMaterial?.diffuse.contents = layer

    scene.rootNode.addChildNode(BoxNode)
