Add UIView to back of scene in SpriteKit game - ios

Question

I am trying to make a advent calendar with a snow affect in swift2. I am using the game template while using SpiteKit.
Here is my code so far:
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 just contains a custom UIView (AdventDoor) along with some more functions
This is what it looks like.
As you can see, the snow SKEmitterNode particles are behind the AdventDoors and not in front.
How would I get my snow to display in front of the UIView Advent Doors instead of behind?

Instead of addsubview for the door, What you need to do is rearrange how your views are laid out. What you need is a UIView as your main view, then you add the SKView as a child to the main view. Then if you want to add the doors in during the scene creation process, you need to do self.view.superview.insertSubView(door, atIndex:0) or self.view.superview.insertSubView(door, belowSubView:self.view) so that the doors are placed behind the scene subview
