從字典創建SKTextureAtlas

Question

如果一個iOS項目有一個UIImages字典，在運行時如何從字典圖像正確創建SKTextureAtlas？我一直無法實現這個目標，儘管Apple的SKTextureAtlas類參考在聲明圖集時建議使用以下內容：便捷init！（字典屬性：[NSObject：AnyObject]）。

例如，下面的代碼如何完成或返工以從tempDictionary中的UIImages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)
