SCNText对齐方式在iOS中不起作用 [英] SCNText Alignment not working in iOS

问题描述

我尝试了右对齐，但是仍然保持左对齐.

I tried right alignment, but it's still left aligned.

let txt = SCNText(string: "TEST", extrusionDepth: 10) 
txt.chamferRadius = 5 //0<chamfer<extrusion depth
txt.firstMaterial.diffuse.contents  = UIColor.whiteColor() 
txt.containerFrame = CGRectMake(-200, -150, 400, 200) //on iPad Air Sim in Landscape
txt.wrapped = true
txt.alignmentMode = kCAAlignmentRight

怎么了?

谢谢！

推荐答案

对齐似乎可行-尝试在测试字符串中添加第二行，例如"TEST\nT"，然后在左右对齐模式之间切换.但是SCNText可以适应其节点的坐标系，因此仅靠对齐并不一定会使文本适合您的场景.

It looks like alignment is working -- try adding a second line to your test string like "TEST\nT" and switching between left and right alignment modes. But SCNText adapts to fit the coordinate system of its node, so alignment alone won't necessarily make the text fit into your scene the way you want it to.

您可以使用节点的pivot属性来调整节点的内容如何适合其父空间.根据

You can tweak how a node's content fits into its parent space using the node's pivot property. Set it to a translation transform (SCNMatrix4MakeTranslation) based on the bounding box of your text and you can change the layout however you like.
