How to display iAd banner in different SpriteKit Scenes - ios

Question

I made simple game with Swift and SpriteKit. Everything seems to work but I have a problem with my iAd Setup. I only want to show the ad banner in specific scenes (main menu and game over) not during the gameplay.
My iAd setup works but only if it is displayed all the time.
My last attempt to fix it was with the NSNotificationCenter method. I have done it as I have seen it in other question/answers here but the app crashes immediately after launch.
Hope that someone could help me. Just let me know if you need more of my code.
Thanks in advance.
GameViewController.swift
class GameViewController: UIViewController, ADBannerViewDelegate {
var adBannerView = ADBannerView(frame: CGRect.zeroRect)
override func viewDidLoad() {
super.viewDidLoad()
NSNotificationCenter.defaultCenter().addObserver(self, selector: "handleNotification", name: "hideAd", object: nil)
NSNotificationCenter.defaultCenter().addObserver(self, selector: "handleNotification", name: "showAd", object: nil)
self.adBannerView.delegate = self
self.adBannerView.hidden = true
adBannerView.center = CGPoint(x: adBannerView.center.x, y: view.bounds.size.height - adBannerView.frame.size.height / 2)
view.addSubview(adBannerView)
if let scene = GameScene.unarchiveFromFile("GameScene") as? GameScene {
// Configure the view.
let skView = self.view as SKView
/* Sprite Kit applies additional optimizations to improve rendering performance */
skView.ignoresSiblingOrder = true
var scene: SKScene = MainMenu(size: skView.bounds.size)
scene.scaleMode = SKSceneScaleMode.AspectFill
skView.presentScene(scene)
}
}
func handleNotification(notification: NSNotification){
if notification.name == "hideAd"{
adBannerView.hidden = true
}else if notification.name == "showAd"{
adBannerView.hidden = false
}
}
//iAD Setup
func bannerViewWillLoadAd(banner: ADBannerView!) {
println("Ad loads")
}
func bannerViewDidLoadAd(banner: ADBannerView!){
println("Ad loaded")
self.adBannerView.hidden = false
}
func bannerViewActionDidFinish(banner: ADBannerView!) {
println("resume scene")
let skView = self.view as SKView
skView.paused = false
}
func bannerViewActionShouldBegin(banner: ADBannerView!, willLeaveApplication willLeave: Bool) -> Bool {
println("pause scene")
let skView = self.view as SKView
skView.paused = true
return true
}
func bannerView(banner: ADBannerView!, didFailToReceiveAdWithError error: NSError!) {
println("Failed to load ad")
self.adBannerView.hidden = true
} more code....
MainMenu.swift
class MainMenu: SKScene{
required init(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
override init(size:CGSize){
super.init(size: size)
NSNotificationCenter.defaultCenter().postNotificationName("showAd", object: nil)

This works for me
In my view controller I have this code:
// Banner Ad
var SH = UIScreen.mainScreen().bounds.height
let transition = SKTransition.fadeWithDuration(1)
var UIiAd: ADBannerView = ADBannerView()
override func viewWillAppear(animated: Bool) {
var BV = UIiAd.bounds.height
UIiAd.delegate = self
UIiAd.frame = CGRectMake(0, SH + BV, 0, 0)
self.view.addSubview(UIiAd)
}
override func viewWillDisappear(animated: Bool) {
UIiAd.delegate = nil
UIiAd.removeFromSuperview()
}
func bannerViewDidLoadAd(banner: ADBannerView!) {
var BV = UIiAd.bounds.height
UIView.beginAnimations(nil, context: nil)
UIView.setAnimationDuration(1) // Time it takes the animation to complete
UIiAd.alpha = 1 // Fade in the animation
UIView.commitAnimations()
}
func bannerView(banner: ADBannerView!, didFailToReceiveAdWithError error: NSError!) {
UIView.beginAnimations(nil, context: nil)
UIView.setAnimationDuration(1)
UIiAd.alpha = 0
UIView.commitAnimations()
}
func showBannerAd() {
UIiAd.hidden = false
var BV = UIiAd.bounds.height
UIView.beginAnimations(nil, context: nil)
UIView.setAnimationDuration(1) // Time it takes the animation to complete
UIiAd.frame = CGRectMake(0, SH - BV, 0, 0) // End position of the animation
UIView.commitAnimations()
}
func hideBannerAd() {
UIiAd.hidden = true
var BV = UIiAd.bounds.height
UIView.beginAnimations(nil, context: nil)
UIView.setAnimationDuration(1) // Time it takes the animation to complete
UIiAd.frame = CGRectMake(0, SH + BV, 0, 0) // End position of the animation
UIView.commitAnimations()
}
override func viewDidLoad() {
super.viewDidLoad()
self.UIiAd.hidden = true
self.UIiAd.alpha = 0
NSNotificationCenter.defaultCenter().addObserver(self, selector: "hideBannerAd", name: "hideadsID", object: nil)
NSNotificationCenter.defaultCenter().addObserver(self, selector: "showBannerAd", name: "showadsID", object: nil)
let scene = GameScene()
// Configure the view.
let skView = self.view as SKView
skView.showsFPS = false
skView.showsNodeCount = false
/* Sprite Kit applies additional optimizations to improve rendering performance */
skView.ignoresSiblingOrder = true
/* Set the scale mode to scale to fit the window */
scene.scaleMode = .AspectFit
scene.anchorPoint = CGPoint(x: 0.5, y: 0.5)
scene.size = skView.bounds.size
skView.presentScene(scene, transition: transition)
}
To display it in the scene I want (for me it's the GameOver scene) I did this:
override func didMoveToView(view: SKView) {
showAds()
// Rest of your code here...
}
func showAds(){
NSNotificationCenter.defaultCenter().postNotificationName("showadsID", object: nil)
}
Basically this code creates a banner off the scene, and when the banner is loaded and the scene gets called, it slides up from the bottom. When you switch scenes, it offsets it again and when you come back to that scene, it slides up from the bottom again. If the banner doesn't load, it's off screen so no worries about it showing a white bar. Also, it sets the alpha to 0 if it doesn't load just in case (makes it invisible). Hope this helps.

I USE THIS TO PRESENT THE iAd Banner in subview
var vc = self.view?.window?.rootViewController
vc?.view.addSubview(adView!)
When I want to hide it when in the game (because iAd reduce FPS) I call
adView!.removeFromSuperview()
When the user finished the Game just add
var vc = self.view?.window?.rootViewController
vc?.view.addSubview(adView!)
to show the iAd banner again
BUT YOU NEED TO IMPLEMENT THIS CODE IN GameViewController
class GameViewController: ADBannerViewDelegate (you needed this too)
also don't forget to import iAd at the top of gameviewcontroller
also import iAd framework to the project
override func viewDidLoad() {
self.ShowAd()
//Have this in view didLoad too
func ShowAd() {
super.viewDidLoad()
adView = ADBannerView(adType: ADAdType.Banner)
adView!.delegate = self
}
func bannerViewDidLoadAd(banner: ADBannerView!) {
self.view.addSubview(adView!)
self.view.layoutIfNeeded()
println("Pass")
}
func bannerView(banner: ADBannerView!, didFailToReceiveAdWithError error: NSError!) {
adView!.removeFromSuperview()
/*var alert = UIAlertController(title: "iAd Message", message:
"iAd Fail To Load", preferredStyle: UIAlertControllerStyle.Alert)
self.presentViewController(alert, animated: false, completion: nil)
alert.addAction(UIAlertAction(title: "dismiss", style: UIAlertActionStyle.Default,
handler: nil))
self.view.layoutIfNeeded()*/
println("fail")
}
