Swift Spritekit以编程方式添加按钮

在SpriteKit中添加按钮并响应其点击并不像在UIKit中那样容易。基本上，您需要创建

SKNode

一个非常简单的场景，中心只有一个红色矩形作为按钮，看起来像这样：

class ButtonTestScene: SKScene {    var button: SKNode! = nil    override func didMoveToView(view: SKView) {        // Create a simple red rectangle that's 100x44        button = SKSpriteNode(color: SKColor.redColor(), size: CGSize(width: 100, height: 44))        // Put it in the center of the scene        button.position = CGPoint(x:CGRectGetMidX(self.frame), y:CGRectGetMidY(self.frame));        self.addChild(button)    }    override func touchesEnded(touches: NSSet, withEvent event: UIEvent) {        // Loop over all the touches in this event        for touch: AnyObject in touches { // Get the location of the touch in this scene let location = touch.locationInNode(self) // Check if the location of the touch is within the button's bounds if button.containsPoint(location) {     println("tapped!") }        }    }}

如果您需要一个外观和动画效果类似于UIKit中的按钮，则需要自己实现；SpriteKit没有内置任何内容。
