iAd unavailable in GameScene.swift? - ios

Question

I have imported iAd into my GameScene.swift file and for some reason I cannot call the self.canDisplayBannerAds() method. Does anyone know how to solve this?

Answer 1

Here is some working code for you that just worked for me. This does not need self.candisplaybannerads = true as I had some issues with that. The ad automatically changes the size according to the screen size and is located at the bottom of the screen.
import iAd
class viewController: UIViewController, ADBannerViewDelegate {
var AdBanner = ADBannerView()
override func viewDidLoad() {
super.viewDidLoad()
/* Ad Banner Settings */
AdBanner = ADBannerView()
AdBanner.frame = CGRectZero
AdBanner.delegate = self
self.AdBanner.frame = CGRectMake(0, self.view.frame.size.height-self.AdBanner.frame.size.height, self.AdBanner.frame.size.width, self.AdBanner.frame.size.height)
AdBanner.backgroundColor = UIColor.clearColor()
self.view.addSubview(AdBanner)
}
/* All iAd Functions */
func bannerViewActionShouldBegin(banner: ADBannerView!, willLeaveApplication willLeave: Bool) -> Bool {
/* whatever you need */
return true
}
func bannerViewActionDidFinish(banner: ADBannerView!) {
/* whatever you need */
}
func bannerViewDidLoadAd(banner: ADBannerView!) {
AdBanner.hidden = false
}
func bannerView(banner: ADBannerView!, didFailToReceiveAdWithError error: NSError!) {
NSLog("Error Loading Ad")
/* whatever you need */
AdBanner.hidden = true
}
func bannerViewWillLoadAd(banner: ADBannerView!) {
/* whatever you need */
}

Answer 2

If you want to use canDisplayBannerAds implement it like so:
import UIKit
import iAd // Import iAd
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
showBanner()
}
func showBanner() {
// Creates a self managed ADBannerView
self.canDisplayBannerAds = true
}
func hideBanner() {
// Removes the ADBannerView
self.canDisplayBannerAds = false
}
Using canDisplayBannerAds creates and manages an ADBannerView for you. There's no need to implement additional methods and the ADBannerView will hide/show itself depending on if there is an advertisement available or not.

Did you remember to inherrit from ADBannerViewDelegate AND import iAd
yourVC: UIViewController, ADBannerViewDelegate {
...
}
