通过官方实例能够替换同一个导出Spine项目的skin，但是如何替换另一个导出Spine中的skin呢，两个项目中使用的骨骼完全相同，因为皮肤太多，不能将所有文件都放置到一个图集中。
var data = controller.skeletonData
var skeleton = controller.skeleton
var customSkin = Skin.create(name: "custom-skin")
customSkin.addSkin(other: data.findSkin(name: "skin-base")!)
customSkin.addSkin(other: data.findSkin(name: "nose/short")!)
customSkin.addSkin(other: data.findSkin(name: "eyelids/girly")!)
customSkin.addSkin(other: data.findSkin(name: "eyes/violet")!)
customSkin.addSkin(other: data.findSkin(name: "hair/brown")!)
customSkin.addSkin(other: data.findSkin(name: "clothes/hoodie-orange")!)
customSkin.addSkin(other: data.findSkin(name: "legs/pants-jeans")!)
customSkin.addSkin(other: data.findSkin(name: "accessories/bag")!)
customSkin.addSkin(other: data.findSkin(name: "accessories/hat-red-yellow")!)
skeleton.skin = customSkin
skeleton.setToSetupPose()
