從字典創建SKTextureAtlas

Question

如果iOS項目具有UIImages字典，那么如何在運行時從字典圖像中正確創建SKTextureAtlas？ 盡管蘋果的SKTextureAtlas類引用在聲明地圖集時建議了以下內容，但我仍未能實現此目標：便利初始化！（字典屬性：[NSObject：AnyObject]）。

例如，如何完成或重新編寫以下代碼，以便根據tempDictionary中的UIImage創建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)
