ios - 从字典创建 SKTextureAtlas

Question

如果 iOS 项目有 UIImages 字典，如何在运行时从字典图像正确创建 SKTextureAtlas？我无法实现这个目标，尽管 Apple 的 SKTextureAtlas 类参考在声明图集时建议以下内容：方便初始化！（字典属性：[NSObject：AnyObject]）。

例如，如何完成或修改以下代码以从 tempDictionary 中的 UIImages 创建 SKTextureAtlas？

var strawberryDrawing:UIImage = UIImage(named: "strawberry")!
var bananaDrawing:UIImage = UIImage(named: "banana")!

var tempDictionary:[String:UIImage] = ["First Fruit":strawberryDrawing, "Second Fruit":bananaDrawing]

var atlasOfFruitDrawings:SKTextureAtlas = ???

Answer 1

let strawberryDrawing = UIImage(named: "strawberry")!
let bananaDrawing = UIImage(named: "banana")!
let tempDictionary: [NSObject:AnyObject] = ["First Fruit":strawberryDrawing, "Second Fruit":bananaDrawing]
let atlasOfFruitDrawings = SKTextureAtlas(dictionary: tempDictionary)
