Using iAd as default ad network, and AdMob if iAd fails

Question

I\'ve built my app this way and everything seems to be working more or less. After hearing about the notoriously low iAd fill rate I decided that this would be the best meth

Answer 1

I ended up with this strategy:

first of all I have created 2 outlets from the storyboard, one for the ADBannerView and another for the GADBannerView

@IBOutlet weak var iadBannerView: ADBannerView!
@IBOutlet weak var adMobBannerView: GADBannerView!

In your viewDidLoad you can do this:

override func viewDidLoad() {
    super.viewDidLoad()
    self.iadBannerView.hidden = true
    self.adMobBannerView.hidden = true
    self.iadBannerView.delegate = self
    NSTimer.scheduledTimerWithTimeInterval(35, target: self, selector: Selector("dispalyGoogleBanner"), userInfo: nil, repeats: false)
}

So here you hidden both banners (if you prefer you can do it directly in storyboard). then you wait 35 second before to display the google ads. So before to display the google ads you basically want to see if iAD it's available.

this is the method used to display the google banner:

 //MARK: - Google banner
    func dispalyGoogleBanner() {
        if !self.isDisplayIAD && !idDisplayADMob {
        idDisplayADMob = true
        self.adMobBannerView.adUnitID = kAdUnitID
        self.adMobBannerView.hidden = false
        self.adMobBannerView.rootViewController = self
        self.adMobBannerView.loadRequest(GADRequest())
        }
    }

so before to display the google banner, we ensure that the iAD banner and the adMob banner are not displayed yet. If that it's the case, then we can send the request to display the ADMob banner.

Here my implementation of the ADBannerViewDelegate

func bannerViewDidLoadAd(banner: ADBannerView!) {
        self.iadBannerView = banner
        self.iadBannerView.hidden = false
        self.adMobBannerView.hidden = true
        idDisplayADMob = false
        self.view.layoutIfNeeded()
    }

    func bannerView(banner: ADBannerView!, didFailToReceiveAdWithError
        error: NSError!) {
            println(error)
            isDisplayIAD = false
            self.iadBannerView.hidden = true
            self.dispalyGoogleBanner()
    }

    func bannerViewActionDidFinish(banner: ADBannerView!) {
        self.iadBannerView = banner
        self.iadBannerView.hidden = true
        isDisplayIAD = false
        dispalyGoogleBanner()
    }

    func bannerViewWillLoadAd(banner: ADBannerView!) {
        //remove the google banner if displayed
        isDisplayIAD = true
        self.iadBannerView.hidden = false
        self.adMobBannerView.hidden = true
        idDisplayADMob = false
        self.view.layoutIfNeeded()
    }

what I basically did on these delegates it's to check if the iAD banner it's available, if that it's case then I'll hidden the adMob banner. If the iAD finished to display the ads, then I'll call the ADMob banner see bannerViewActionDidFinish

You can easily adapt this logic tu your implementation.
