円を描いて、その中にテキストを入れたいです。私に何ができる？

円を移動またはサイズ変更すると、テキストも移動またはサイズ変更されます

これ欲しい

        var color = UIColor(red: 0x00, green: 0x44, blue: 0x44, alpha: 1)
        var Circle = SKShapeNode(circleOfRadius: 100 )
        Circle.position = CGPointMake(frame.midX, frame.midY)
        Circle.strokeColor = SKColor.blackColor()
        Circle.glowWidth = 1.0
        Circle.fillColor = color

        let myLabel = SKLabelNode(fontNamed:"Chalkduster")
        myLabel.text = "Hello, World!";
        myLabel.fontSize = 60;
        myLabel.position = CGPointMake(frame.midX, frame.midY)
        myLabel.fontColor = UIColor.blackColor()

        self.addChild(Circle)

両方を一度にドラッグする 1 つの方法は、両方を同じビューに追加し、その後、以下のコードに示すようなタッチ イベントで両方の位置を変更することです。

import SpriteKit

class GameScene: SKScene {

    var deltaPoint = CGPointZero
    let myLabel = SKLabelNode(fontNamed:"Chalkduster")
    var Circle = SKShapeNode(circleOfRadius: 100 )

    override func didMoveToView(view: SKView) {
        /* Setup your scene here */
        var color = UIColor(red: 0x00, green: 0x44, blue: 0x44, alpha: 1)

        Circle.position = CGPointMake(frame.midX, frame.midY)
        Circle.strokeColor = SKColor.blackColor()
        Circle.glowWidth = 1.0
        Circle.fillColor = color

        myLabel.text = "Hello, World!";
        myLabel.fontSize = 20
        myLabel.position = CGPointMake(Circle.frame.midX, Circle.frame.midY)
        myLabel.fontColor = UIColor.blackColor()

        // Add them into same scene
        self.addChild(Circle)
        self.addChild(myLabel)

    }

    override func touchesMoved(touches: Set<NSObject>, withEvent event: UIEvent) {

        if let touch = touches.first as? UITouch {
            let currentPoint = touch.locationInNode(self)
            let previousPoint = touch.previousLocationInNode(self)
            deltaPoint = CGPointMake(currentPoint.x - previousPoint.x, currentPoint.y - previousPoint.y)
        }

    }

    override func touchesEnded(touches: Set<NSObject>, withEvent event: UIEvent) {

        deltaPoint = CGPointZero
    }

    override func touchesCancelled(touches: Set<NSObject>!, withEvent event: UIEvent!) {

        deltaPoint = CGPointZero
    }

    override func update(currentTime: CFTimeInterval) {
        /* Called before each frame is rendered */
        var newPoint = CGPointMake(self.myLabel.position.x + self.deltaPoint.x, self.myLabel.position.y + self.deltaPoint.y)

        // you can drag both item at same time
        myLabel.position = newPoint
        Circle.position = newPoint

        deltaPoint = CGPointZero
    }
}

UPDATED: Using your full example.

Not a SpritKit user, but I believe that each node has an .addChild(). So it should be possible to add it as a child to your circle:

var color = UIColor(red: 0x00, green: 0x44, blue: 0x44, alpha: 1)
var Circle = SKShapeNode(circleOfRadius: 100 )
Circle.position = CGPointMake(frame.midX, frame.midY)
Circle.strokeColor = SKColor.blackColor()
Circle.glowWidth = 1.0
Circle.fillColor = color

let myLabel = SKLabelNode(fontNamed:"Chalkduster")
myLabel.text = "Hello, World!";
myLabel.fontSize = 60;
// Using half of the circle (center point)
myLabel.position = CGPointMake(Circle.frame.midX, Circle.frame.midY)
myLabel.fontColor = UIColor.blackColor()

Circle.addChild(myLabel)
self.addChild(Circle)

Position would then be relative to the circles frame.

ラベルのフォント サイズを円のサイズに比例させる必要があります。

これはボタンを作成するための関数です:

func createCircleButton(position: CGPoint, buttonSize: CGFloat, yourText: String) {

    let circle = SKShapeNode( circleOfRadius: buttonSize)
    circle.position = position
    circle.fillColor = SKColor.blueColor()

    let label = SKLabelNode(fontNamed:"ArialMT")
    label.text = yourText
    label.fontSize = circle.frame.size.height / 6;
    label.fontColor = SKColor.whiteColor()

    circle.addChild(label)
    self.addChild(circle)

}

次のように追加します。

self.createCircleButton(CGPointMake(self.frame.size.width / 2, self.frame.size.height / 2), buttonSize: self.frame.size.height / 5, yourText: "Your text")
