Question

我正试图在swift2中制作一个带有雪影响的降临节日历。我在使用SpiteKit时使用游戏模板。

到目前为止，这是我的代码：

GameScene.swift

import SpriteKit

class GameScene: SKScene {
    /*override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
        if let touch = touches.first {
            let location = touch.locationInNode(self)
            print(location)
        }
    }*/

    func test()
    {
        //Generate Doors

        //Initilization
        var adventDoors = [AdventDoor]()
        let offset = CGVector(dx: 10,dy: 10)
        var size = CGRectMake(offset.dx, offset.dy, 60, 60)

        var ypos:CGFloat = 20
        var xpos:CGFloat = 10
        var index = 0
        var xDoor = AdventDoor(frame: size)
        let randomIdentifier = [Int](1...24).shuffle()
        for _ in 1...4
        {
            for i in 1...6
            {
                size = CGRectMake(xpos, ypos, 60, 60)
                xDoor = AdventDoor(frame: size)
                xDoor.opaque = false
                xDoor.restorationIdentifier = "\(randomIdentifier[index])"
                xDoor.generateDoor()
                adventDoors.append(xDoor)
                print("1...6")
                ypos += 80
                //xpos += 20
                index++

                if i == 6
                {
                    print("Moving to next view")
                }

            }

            xpos += 80
            ypos = 20
        }

        size = CGRectMake(10, 500, 300, 60)
        xDoor = AdventDoor(frame: size)
        xDoor.opaque = false
        xDoor.restorationIdentifier = "\(25)"
        xDoor.generateDoor()
        adventDoors.append(xDoor)


        index = 0

        for door in adventDoors
        {
            index++
            self.view?.addSubview(door)
        }
        print("\(index) doors were added")
    }
}

GameViewController.swift

class GameViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()



        if let scene = GameScene(fileNamed:"GameScene") {

            // Configure the view.
            let skView = self.view as! SKView
            //skView.showsFPS = true
            //skView.showsNodeCount = true

            /* Sprite Kit applies additional optimizations to improve rendering performance */
            skView.ignoresSiblingOrder = true

            /* Set the scale mode to scale to fit the window */
            scene.scaleMode = .AspectFill
            scene.backgroundColor = UIColor.greenColor()
            skView.presentScene(scene)

            scene.test()

            //Snow
            let wrappedSnowPath = NSBundle.mainBundle().pathForResource("Snow", ofType: "sks")
            if let snowPath = wrappedSnowPath
            {
                let snowEmitter:SKEmitterNode = NSKeyedUnarchiver.unarchiveObjectWithFile(snowPath) as! SKEmitterNode
                let screenBounds = UIScreen.mainScreen().bounds
                snowEmitter.position = CGPointMake(screenBounds.width, screenBounds.height)
                scene.addChild(snowEmitter)
            }
        }
    }

    override func shouldAutorotate() -> Bool {
        return true
    }

    override func supportedInterfaceOrientations() -> UIInterfaceOrientationMask {
        if UIDevice.currentDevice().userInterfaceIdiom == .Phone {
            return .AllButUpsideDown
        } else {
            return .All
        }
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Release any cached data, images, etc that aren't in use.
    }

    override func prefersStatusBarHidden() -> Bool {
        return true
    }
}

AdventDoor.swift 只包含一个自定义UIView（AdventDoor）以及更多功能

这就是它的样子。

正如您所看到的，雪SKEmitterNode粒子位于AdventDoors后面而不在前面。

我怎样才能让我的雪在UIView Advent Doors门前展示而不是落后？

而不是addsubview门，你需要做的是重新安排你的观点的布局。您需要的是UIView作为主视图，然后将SKView作为子视图添加到主视图中。然后，如果您想在场景创建过程中添加门，则需要执行self.view.superview.insertSubView(door, atIndex:0)或self.view.superview.insertSubView(door, belowSubView:self.view)，以便将门放置在场景子视图后面

在SpriteKit游戏中将UIView添加到场景的后面
