紋理圖集不起作用

Question

我不明白什麼是錯的。我編寫的代碼，代碼中沒有錯誤和問題，終端中沒有消息，圖集包含.png圖像。 所以，當我編譯我的代碼時，紋理不顯示。我能看到的只有紅十字。我如何解決這個問題？

這是我的代碼：

import SpriteKit 

class GameScene: SKScene { 


    override func didMoveToView(view: SKView) { 
     self.backgroundColor = UIColor(red: 0.4, green: 0.6, blue: 0.5, alpha: 1.0) 

     let bee = SKSpriteNode() 
     bee.position = CGPoint(x: 250, y: 250) 
     bee.size = CGSize(width: 40, height: 40) 
     self.addChild(bee) 

     let beeAtlas = SKTextureAtlas(named: "bee") 
     let beeFrames : [SKTexture] = 
     [beeAtlas.textureNamed("c1.png"), 
     beeAtlas.textureNamed("c2.png")] 

     let flyAction = SKAction.animateWithTextures(beeFrames, timePerFrame: 0.5) 
     let beeAction = SKAction.repeatActionForever(flyAction) 
     bee.runAction(beeAction) 
} 

    override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) { 

    } 

}

我現在在我的電腦上，我寫這段代碼，讓我知道，如果它的工作原理：

import SpriteKit 

class GameScene: SKScene { 


var bee = SKSpriteNode() 
var beeAtlas = SKTextureAtlas() 
var beeFrames = [SKTexture]() 

override func didMoveToView(view: SKView) { 
    self.backgroundColor = UIColor(red: 0.4, green: 0.6, blue: 0.5, alpha: 1.0) 

    beeAtlas = SKTextureAtlas(named: "bee") 

    for i in 1...beeAtlas.textureNames.count { 
     var name = "c\(i).png" 
     beeFrames.append(SKTexture(imageNamed: name)) 
    } 

    bee = SKSpriteNode(imageNamed: beeAtlas.textureNames[0] as! String) 
    bee.position = CGPoint(x: 250, y: 250) 
    bee.size = CGSize(width: 40, height: 40) 

    bee.runAction(SKAction.repeatActionForever(SKAction.animateWithTextures(beeFrames, timePerFrame: 0.5))) 

    self.addChild(bee) 
} 
}
