Prerequisites
- Import the Google Mobile Ads SDK, either by itself or as part of Firebase.
- Integrate the Native ad format.
GADMediaContent
Native ads provide access to aGADMediaContent
class that is used to get information
about media content which could be a video or an image. It is also used to
control the video ad playback listen for playback events. You can access the
media content object via the .mediaContent
property on the ad.
The
GADMediaContent
object contains information such as the aspect ratio and duration of video. The
snippet below shows how to get the aspect ratio and duration of a native ad.
Swift
if myNativeAd.mediaContent.hasVideoContent { let mediaAspectRatio = CGFloat(myNativeAd.mediaContent.aspectRatio) let duration = myNativeAd.mediaContent.duration ... }
Objective-C
if(myNativeAd.mediaContent.hasVideoContent) { CGFloat mediaAspectRatio = myNativeAd.mediaContent.aspectRatio; NSTimeInterval duration = myNativeAd.mediaContent.duration; ... }
GADVideoController
The GADMediaContent
object has a reference to a
GADVideoController
object. The GADVideoController
object allows publishers to respond to video
events.
This GADMediaContent
object can be obtained by calling mediaContent.videoController
.
Callbacks for video events
To handle specific video events you need to write a class that implements the
GADVideoControllerDelegate
protocol. The methods of the protocol are all optional.
The following example shows how to implement the delegate protocol:
Swift
class ViewController: GADUnifiedNativeAdLoaderDelegate, GADVideoControllerDelegate { private var adLoader: GADAdLoader? func viewDidLoad() { super.viewDidLoad() let videoOptions = GADVideoOptions() videoOptions.customControlsRequested = true adLoader = GADAdLoader( adUnitID: "ca-app-pub-3940256099942544/3986624511", rootViewController: self, adTypes: [kGADAdLoaderAdTypeUnifiedNative], options: [videoOptions]) adLoader?.delegate = self adLoader?.load(GADRequest()) } func adLoader( _ adLoader: GADAdLoader?, didReceive nativeAd: GADUnifiedNativeAd? ) { // Set the videoController's delegate to be notified of video events. nativeAd?.mediaContent.videoController.delegate = self } // GADVideoControllerDelegate methods func videoControllerDidPlayVideo(_ videoController: GADVideoController) { // Implement this method to receive a notification when the video controller // begins playing the ad. } func videoControllerDidPauseVideo(_ videoController: GADVideoController) { // Implement this method to receive a notification when the video controller // pauses the ad. } func videoControllerDidEndVideoPlayback(_ videoController: GADVideoController) { // Implement this method to receive a notification when the video controller // stops playing the ad. } func videoControllerDidMuteVideo(_ videoController: GADVideoController) { // Implement this method to receive a notification when the video controller // mutes the ad. } func videoControllerDidUnmuteVideo(_ videoController: GADVideoController) { // Implement this method to receive a notification when the video controller // unmutes the ad. } }
Objective-C
@interface ViewController () <GADUnifiedNativeAdLoaderDelegate, GADVideoControllerDelegate> @property(nonatomic, strong) GADAdLoader *adLoader; @end @implementation ViewController - (void)viewDidLoad { [super viewDidLoad]; GADVideoOptions *videoOptions = [[GADVideoOptions alloc] init]; videoOptions.customControlsRequested = YES; self.adLoader = [[GADAdLoader alloc] initWithAdUnitID:@"ca-app-pub-3940256099942544/3986624511" rootViewController:self adTypes:@[ kGADAdLoaderAdTypeUnifiedNative ] options:@[ videoOptions ]]; self.adLoader.delegate = self; [self.adLoader loadRequest:[GADRequest request]]; } - (void)adLoader:(GADAdLoader *)adLoader didReceiveUnifiedNativeAd:(GADUnifiedNativeAd *)nativeAd { // Set the videoController's delegate to be notified of video events. nativeAd.mediaContent.videoController.delegate = self; } // GADVideoControllerDelegate methods - (void)videoControllerDidPlayVideo:(nonnull GADVideoController *)videoController { // Implement this method to receive a notification when the video controller // begins playing the ad. } - (void)videoControllerDidPauseVideo:(nonnull GADVideoController *)videoController { // Implement this method to receive a notification when the video controller // pauses the ad. } - (void)videoControllerDidEndVideoPlayback:(nonnull GADVideoController *)videoController { // Implement this method to receive a notification when the video controller // stops playing the ad. } - (void)videoControllerDidMuteVideo:(nonnull GADVideoController *)videoController { // Implement this method to receive a notification when the video controller // mutes the ad. } - (void)videoControllerDidUnmuteVideo:(nonnull GADVideoController *)videoController { // Implement this method to receive a notification when the video controller // unmutes the ad. } @end
