从字典中创建SKTextureAtlas

Question

如果iOS项目有一个UIImages字典，那么如何在运行时从字典映像中正确地创建SKTextureAtlas？我还没能实现这个目标，尽管苹果的SKTextureAtlas类引用在声明地图集时建议如下:方便，init！(字典属性: NSObject : AnyObject)。

例如，如何完成或重新工作以下代码以从SKTextureAtlas中的UIImages创建tempDictionary？

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)
