# Fullscreen interstitial Ad of Google Mobile Ads

Fullscreen interstitial ad is an advertisement "content" By using this feature, GoogleMobileAd's Fullscreen Interstitial will display interstitial advertisements for each ad network with Geniee's mediation.

# Preparation for implementation

# Add GoogleMobileAds

Add the following to Podfile.

pod 'Google-Mobile-Ads-SDK'

<key>GADApplicationIdentifier</key>
<string>ca-app-pub-################~##########</string>

# Add GNAdGoogleMediationAdapter

# Introduce with Cocoapods

Add the following to Podfile.

pod 'Geniee-Google-Mediation-Adapter'

# Introduction with manual

# Common introduction contents

For GNAdGoogleMediationAdapter 5.1.6 and later versions, the following steps are unnecessary.

# Add Geniee SDK

For installation of Geniee SDK, see the start guide.

Start guide

# Add SDK and adapter for each ad network

For fullscreen interstitial, it is necessary to set SDK and adapter for each ad network. Please refer to the introduction method from the link of the ad network from the following.

# Implementation of fullscreen interstitial

By using the UnitID that set mediation on GoogleAdManager/AdMob management screen, you can display the mediated fullscreen ads.
For details on how to implement the fullscreen, please refer to the following site.

# Response when Google Ad Manager Fullscreen Interstitial Ad is No Fill

If Google Ad Manager's Fullscreen Interstitial fails to load, you can prevent the spill of ads by calling Geniee SDK. The implementation procedure is as follows.

# Preparation for implementation

Import GNSFullscreenInterstitialAd of Geniee SDK.

• ObjectiveC
  Import the header file and add Delegate.

Example：ViewController.h

#import <GNAdSDK/GNSRequest.h>
#import <GNAdSDK/GNSFullscreenInterstitialAdDelegate.h>
@interface ViewController <GADInterstitialDelegate, GNSFullscreenInterstitialAdDelegate>

• Swift
  Add a header file with the following contents.

#import <GNAdSDK/GNSRequest.h>
#import <GNAdSDK/GNSFullscreenInterstitialAdDelegate.h>

Select the project from the navigator area, then select "TARGET" => "Build Settings".

Add path of the header file created above to "Objective-C Bridging Header".

# Delegate method implementation

implementation of GNSFullscreenInterstitialAdDelegate.

• ObjectiveC
  About Delegate implementation
  Set Delegate.

[GNSFullscreenInterstitialAd sharedInstance].delegate = self;

To receive notification from the SDK, implement the method of GNSFullscreenInterstitialAdDelegate.

/// Tells the delegate that the interstitial ad failed to load.
- (void)fullscreenInterstitial:(GNSFullscreenInterstitialAd *)fullscreenInterstitialAd
    didFailToLoadWithError:(NSError *)error {
}

/// Tells the delegate that the interstitial ad loaded.
- (void)fullscreenInterstitialDidReceiveAd:(GNSFullscreenInterstitialAd *)fullscreenInterstitialAd {
}

/// Tells the delegate that the interstitial ad started showing. 
(void)fullscreenInterstitialWillPresentScreen:(GNSFullscreenInterstitialAd *)fullscreenInterstitialAd {
}

/// Tells the delegate that the interstitial ad closed.
- (void)fullscreenInterstitialAdDidClose:(GNSFullscreenInterstitialAd *)fullscreenInterstitialAd {
}

• Swift
  About Delegate implementation
  Set Delegate.

GNSFullscreenInterstitialAd.sharedInstance().delegate = self

To receive notification from the SDK, implement the method of GNSFullscreenInterstitialAdDelegate.

extension ViewController : GNSFullscreenInterstitialAdDelegate {
    
    // Tells the delegate that a interstitial ad was received.
    func fullscreenInterstitialDidReceiveAd(_ fullscreenInterstitialAd: GNSFullscreenInterstitialAd!) {
    }
    
    // Tells the delegate that the interstitial ad failed to load.
    func fullscreenInterstitial(_ fullscreenInterstitialAd: GNSFullscreenInterstitialAd!, didFailToLoadWithError error: Error!) {
    }
    
    // Tells the delegate that the interstitial ad started showing.
    func fullscreenInterstitialWillPresentScreen(_ fullscreenInterstitialAd: GNSFullscreenInterstitialAd!) {
    }
    
    // Tells the delegate that the interstitial ad closed.
    func fullscreenInterstitialAdDidClose(_ fullscreenInterstitialAd: GNSFullscreenInterstitialAd!) {
    }

}

# Load fullscreen interstitial ad

Implement the Geniee SDK full-screen interstitial load method in the method that will be called if the Google Ad Manager load fails.
If you want to show another movie after the completion of playback of one movie, you need to make a load request again.

• ObjectiveC

GAMRequest *request = [GAMRequest request];
[GAMInterstitialAd loadWithAdManagerAdUnitID:@"YOUR_UNIT_ID" request:request completionHandler:^(GAMInterstitialAd *ad, NSError *error) {
    if (error) {
        GNSRequest *request = [GNSRequest request];
        [[GNSFullscreenInterstitialAd sharedInstance] loadRequest:request withZoneID:@"YOUR_SSP_ZONE_ID"];
        return;
    }
    self.interstitial = ad;
    self.interstitial.fullScreenContentDelegate = self;
}];

• Swift

let request = GAMRequest()
GAMInterstitialAd.load(withAdManagerAdUnitID: "YOUR_UNIT_ID", request: request, completionHandler: { (ad, error) in
    if let error = error {
        let request = GNSRequest()
        GNSFullscreenInterstitialAd.sharedInstance().load(request, withZoneID: "YOUR_ZONE_ID")
        return
    }
    self.interstitial = ad
    self.interstitial.fullScreenContentDelegate = self
})

# Display fullscreen interstitial

In the order of Google Ad Manager → Geniee SDK, check whether load is completed, and show ad by show method.
Please be sure to execute show after running Google Ad Manager's Load.

• ObjectiveC

if (self.interstitial) {
    [self.interstitial presentFromRootViewController:self];
} else if ([[GNSFullscreenInterstitialAd sharedInstance] canShow]) {
   [[GNSFullscreenInterstitialAd sharedInstance] show:self];
}

• Swift

if let ad = interstitial {
    ad.present(fromRootViewController: self)
} else if GNSFullscreenInterstitialAd.sharedInstance().canShow() {
    GNSFullscreenInterstitialAd.sharedInstance().show(self)
}
