Swift 2.0，SpriteKit - 滚动视图不使用页面。

Question

好的，所以我有一个滚动视图，它已经被子类化，可以应用于我在这里提出的上一个问题中的任何场景：

SpriteKit, Swift 2.0 - ScrollView in reverse

import Foundation
import SpriteKit

/// Nodes touched
var nodesTouched: [AnyObject] = [] // global

/// Scroll direction
enum ScrollDirection: Int {
case None = 0
case Vertical
case Horizontal
}

class CustomScrollView: UIScrollView {

// MARK: - Static Properties

/// Touches allowed
static var disabledTouches = false

/// Scroll view
private static var scrollView: UIScrollView!

// MARK: - Properties

/// Current scene
private weak var currentScene: SKScene?

/// Moveable node
private var moveableNode: SKNode?

/// Scroll direction
private var scrollDirection = ScrollDirection.None

// MARK: - Init
init(frame: CGRect, scene: SKScene, moveableNode: SKNode, scrollDirection: ScrollDirection) {
    print("Scroll View init")
    super.init(frame: frame)

    CustomScrollView.scrollView = self
    self.scrollDirection = scrollDirection
    self.currentScene = scene
    self.moveableNode = moveableNode
    self.frame = frame
    indicatorStyle = .White
    scrollEnabled = true
    //self.minimumZoomScale = 1
    //self.maximumZoomScale = 3
    canCancelContentTouches = false
    userInteractionEnabled = true
    delegate = self

    // flip for spritekit (only needed for horizontal)
    if self.scrollDirection == .Horizontal {
        let flip = CGAffineTransformMakeScale(-1,-1)
        self.transform = flip
    }
}

required init?(coder aDecoder: NSCoder) {
    fatalError("init(coder:) has not been implemented")
    }
}

 // MARK: - Touches
 extension CustomScrollView {

/// began
override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
    print("Touch began scroll view")

    guard !CustomScrollView.disabledTouches else { return }
    currentScene?.touchesBegan(touches, withEvent: event)
}

/// moved
override func touchesMoved(touches: Set<UITouch>, withEvent event: UIEvent?) {
    print("Touch moved scroll view")

    guard !CustomScrollView.disabledTouches else { return }
    currentScene?.touchesMoved(touches, withEvent: event)
}

/// ended
override func touchesEnded(touches: Set<UITouch>, withEvent event: UIEvent?) {
    print("Touch ended scroll view")

    guard !CustomScrollView.disabledTouches else { return }
    currentScene?.touchesEnded(touches, withEvent: event)
}

/// cancelled
override func touchesCancelled(touches: Set<UITouch>?, withEvent event: UIEvent?) {
    print("Touch cancelled scroll view")

    guard !CustomScrollView.disabledTouches else { return }
    currentScene?.touchesCancelled(touches, withEvent: event)
   }
}

 // MARK: - Touch Controls
 extension CustomScrollView {

/// Disable
class func disable() {
    print("Disabled scroll view")
    CustomScrollView.scrollView?.userInteractionEnabled = false
    CustomScrollView.disabledTouches = true
}

/// Enable
class func enable() {
    print("Enabled scroll view")
    CustomScrollView.scrollView?.userInteractionEnabled = true
    CustomScrollView.disabledTouches = false
   }
 }

 // MARK: - Delegates
 extension CustomScrollView: UIScrollViewDelegate {

/// did scroll
func scrollViewDidScroll(scrollView: UIScrollView) {
    print("Scroll view did scroll")

    if scrollDirection == .Horizontal {
        moveableNode!.position.x = scrollView.contentOffset.x
    } else {
        moveableNode!.position.y = scrollView.contentOffset.y
      }
    }
 }

唯一的问题是滚动视图使用页面，而我希望它看起来的方式只滚动精灵，就像 raywenderlich 一样，其中所有精灵都是唯一移动的东西，所以我不必滚动多个页面以找到一个精灵。

项目可以在这里找到：

Raywenderlich Project

因为他们使用他们的 gameViewController，所以我无法像上面那样通过子类滚动视图来实现它。

我不明白你在这里问什么。我刚刚查看了 RayWenderlich 教程，它与我的 GitHub 示例项目完全相同。他们只是让精灵更靠近在一起，在我的项目中为了演示目的，我将每个精灵放在一个新页面上。

如果您只想让精灵滚动，只需将精灵添加到可移动节点，其余的照常直接添加到场景中。

addChild(background)
moveableNode.addChild(sprite1)

改变精灵的位置，使它们更靠近。您基本上将第一个精灵添加到滚动视图中的第一页，然后根据先前的精灵 x 位置定位其他精灵。您也可以将这些精灵添加到 sprite1。

let sprite1 = SKSpriteNode(color: SKColor.redColor(), size: CGSize(width: 50, height: 50))
sprite1.position = CGPointMake(0, 0)
page1ScrollView.addChild(sprite1)

let sprite2 = SKSpriteNode(color: SKColor.redColor(), size: CGSize(width: 50, height: 50))
sprite2.position = CGPointMake(sprite1.position.x + (sprite2.size.width * 1.5), sprite1.position.y)
sprite1.addChild(sprite2)

let sprite3 = SKSpriteNode(color: SKColor.redColor(), size: CGSize(width: 50, height: 50))
sprite3.position = CGPointMake(sprite2.position.x + (sprite3.size.width * 1.5), sprite1.position.y)
sprite1.addChild(sprite3)

我更新了我的 gitHub 项目以实际展示这一点 https://github.com/crashoverride777/Swift2-SpriteKit-UIScrollView-Helper
