原生影片廣告

必要條件

GADMediaContent

原生廣告會提供 GADMediaContent 類別的存取權，用於取得媒體內容 (可能是影片或圖片) 的相關資訊。還可控制影片廣告播放是否監聽播放事件。您可以透過廣告的 .mediaContent 屬性存取媒體內容物件。

GADMediaContent 物件包含影片的顯示比例和時間長度等資訊。下列程式碼片段說明如何取得原生廣告的顯示比例和時間長度。

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

GADMediaContent 物件具有對 GADVideoController 物件的參照。GADVideoController 物件可讓發布商回應影片事件。

您可以呼叫 GADMediaContent.videoController 取得這個 GADVideoController 物件。

影片事件的回呼

如要處理特定的影片事件，您需要編寫實作 GADVideoControllerDelegate 通訊協定的類別。通訊協定的方法都是選用的。

以下範例說明如何實作委派通訊協定：

Swift

class ViewController: GADNativeAdLoaderDelegate, 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: [GADAdLoaderAdTypeNative],
        options: [videoOptions])
    adLoader?.delegate = self
    adLoader?.load(GADRequest())

  }

  func adLoader(
      _ adLoader: GADAdLoader?,
      didReceive nativeAd: GADNativeAd?
  ) {
    // 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 () <GADNativeAdLoaderDelegate,
    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:@[ GADAdLoaderAdTypeNative ]
                                    options:@[ videoOptions ]];
  self.adLoader.delegate = self;
  [self.adLoader loadRequest:[GADRequest request]];

}

- (void)adLoader:(GADAdLoader *)adLoader
    didReceiveNativeAd:(GADNativeAd *)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.
}
