Peristiwa kustom iklan reward

Prasyarat

Meminta iklan reward

Saat item baris peristiwa kustom dicapai dalam rantai mediasi waterfall, metode loadRewarded:adConfiguration:completionHandler: dipanggil pada nama class yang Anda berikan saat membuat peristiwa kustom. Dalam hal ini, metode tersebut berada di SampleCustomEvent, yang kemudian memanggil metode loadRewarded:adConfiguration:completionHandler: di SampleCustomEventRewarded.

Untuk meminta iklan reward, buat atau ubah class yang mengimplementasikan GADMediationAdapter dan loadRewarded:adConfiguration:completionHandler:. Jika class yang memperluas GADMediationAdapter sudah ada, terapkan loadRewarded:adConfiguration:completionHandler: di sana. Selain itu, buat class baru untuk menerapkan GADMediationRewardedAd.

Dalam contoh peristiwa kustom, SampleCustomEvent mengimplementasikan antarmuka GADMediationAdapter, lalu mendelegasikan ke SampleCustomEventRewarded.

Swift

import GoogleMobileAds

class SampleCustomEvent: NSObject, GADMediationAdapter {

  fileprivate var rewardedAd: SampleCustomEventRewarded?
  ...

  func loadRewarded(
    for adConfiguration: GADMediationRewardedAdConfiguration,
    completionHandler: @escaping GADMediationRewardedLoadCompletionHandler
  ) {
    self.rewardedAd = SampleCustomEventRewarded()
    self.rewardedAd?.loadRewarded(
      for: adConfiguration, completionHandler: completionHandler)
  }
}

Objective-C

#import "SampleCustomEvent.h"

@implementation SampleCustomEvent
...

SampleCustomEventRewarded *sampleRewarded;

- (void)loadRewardedForAdConfiguration:
            (GADMediationRewardedAdConfiguration *)adConfiguration
                     completionHandler:
                         (GADMediationRewardedLoadCompletionHandler)
                             completionHandler {
  sampleRewarded = [[SampleCustomEventRewarded alloc] init];
  [sampleRewarded loadRewardedForAdConfiguration:adConfiguration
                               completionHandler:completionHandler];
}

SampleCustomEventRewarded bertanggung jawab atas tugas berikut:

Memuat iklan reward.
Mengimplementasikan protokol GADMediationRewardedAd.
Menerima dan melaporkan callback peristiwa iklan ke Google Mobile Ads SDK.

Parameter opsional yang ditentukan di UI Ad Manager disertakan dalam konfigurasi iklan. Parameter ini dapat diakses melalui adConfiguration.credentials.settings[@"parameter"]. Parameter ini biasanya adalah ID unit iklan yang diperlukan SDK jaringan iklan saat membuat instance objek iklan.

Swift

class SampleCustomEventRewarded: NSObject, GADMediationRewardedAd {
  /// The Sample Ad Network rewarded ad.
  var nativeAd: SampleRewarded?

  /// The ad event delegate to forward ad rendering events to the Google Mobile Ads SDK.
  var delegate: GADMediationRewardedAdEventDelegate?

  /// Completion handler called after ad load.
  var completionHandler: GADMediationRewardedLoadCompletionHandler?

  func loadRewarded(
    for adConfiguration: GADMediationRewardedAdConfiguration,
    completionHandler: @escaping GADMediationRewardedLoadCompletionHandler
  ) {
    rewarded = SampleRewarded.init(
      adUnitID: adConfiguration.credentials.settings["parameter"] as? String)
    rewarded?.delegate = self
    let adRequest = SampleAdRequest()
    adRequest.testMode = adConfiguration.isTestRequest
    self.completionHandler = completionHandler
    rewarded?.fetchAd(adRequest)
  }
}

Objective-C

#import "SampleCustomEventRewarded.h"

@interface SampleCustomEventRewarded () <SampleRewardedAdDelegate,
                                         GADMediationRewardedAd> {
  /// The sample rewarded ad.
  SampleRewarded *_rewardedAd;

  /// The completion handler to call when the ad loading succeeds or fails.
  GADMediationRewardedLoadCompletionHandler _loadCompletionHandler;

  /// The ad event delegate to forward ad rendering events to the Google Mobile Ads SDK.
  id <GADMediationRewardedAdEventDelegate> _adEventDelegate;
}
@end

- (void)loadRewardedAdForAdConfiguration:(GADMediationRewardedAdConfiguration *)adConfiguration
                       completionHandler:
                           (GADMediationRewardedLoadCompletionHandler)completionHandler {
  __block atomic_flag completionHandlerCalled = ATOMIC_FLAG_INIT;
  __block GADMediationRewardedLoadCompletionHandler originalCompletionHandler =
      [completionHandler copy];

  _loadCompletionHandler = ^id<GADMediationRewardedAdEventDelegate>(
      _Nullable id<GADMediationRewardedAd> ad, NSError *_Nullable error) {
    // Only allow completion handler to be called once.
    if (atomic_flag_test_and_set(&completionHandlerCalled)) {
      return nil;
    }

    id<GADMediationRewardedAdEventDelegate> delegate = nil;
    if (originalCompletionHandler) {
      // Call original handler and hold on to its return value.
      delegate = originalCompletionHandler(ad, error);
    }

    // Release reference to handler. Objects retained by the handler will also be released.
    originalCompletionHandler = nil;

    return delegate;
  };

  NSString *adUnit = adConfiguration.credentials.settings[@"parameter"];
  _rewardedAd = [[SampleRewardedAd alloc] initWithAdUnitID:adUnit];
  _rewardedAd.delegate = self;
  SampleAdRequest *adRequest = [[SampleAdRequest alloc] init];
  adRequest.testMode = adConfiguration.isTestRequest;
  [_rewardedAd fetchAd:adRequest];
}

Baik iklan berhasil diambil atau mengalami error, Anda akan memanggil GADMediationRewardedLoadCompletionHandler. Jika berhasil, teruskan class yang mengimplementasikan GADMediationRewardedAd dengan nilai nil untuk parameter error; jika gagal, teruskan error yang Anda alami.

Biasanya, metode ini diterapkan di dalam callback dari SDK pihak ketiga yang diterapkan adaptor Anda. Untuk contoh ini, Sample SDK memiliki SampleRewardedAdDelegate dengan callback yang relevan:

Swift

func rewardedDidLoad(_ interstitial: SampleRewarded) {
  if let handler = completionHandler {
    delegate = handler(self, nil)
  }
}

func rewarded(
  rewarded: SampleRewarded, didFailToLoadAdWith errorCode: SampleErrorCode
) {
  let error =
    SampleCustomEventUtils.SampleCustomEventErrorWithCodeAndDescription(
      code: SampleCustomEventErrorCode
        .SampleCustomEventErrorAdLoadFailureCallback,
      description:
        "Sample SDK returned an ad load failure callback with error code: \(errorCode)"
    )
  if let handler = completionHandler {
    delegate = handler(nil, error)
  }
}

Objective-C

- (void)rewardedDidLoad:(SampleRewarded *)rewarded {
  _adEventDelegate = _loadCompletionHandler(self, nil);
}

- (void)rewarded:(SampleInterstitial *)rewarded
    didFailToLoadAdWithErrorCode:(SampleErrorCode)errorCode {
  NSError *error = SampleCustomEventErrorWithCodeAndDescription(
      SampleCustomEventErrorAdLoadFailureCallback,
      [NSString stringWithFormat:@"Sample SDK returned an ad load failure "
                                 @"callback with error code: %@",
                                 errorCode]);
  _adEventDelegate = _loadCompletionHandler(nil, error);
}

GADMediationrewardedAd memerlukan penerapan metode present(viewController:) untuk menampilkan iklan:

Swift

func present(from viewController: UIViewController) {
  if let rewarded = rewarded, rewarded.isRewardedLoaded {
    rewarded.show()
  }
}

Objective-C

- (void)presentFromViewController:(UIViewController *)viewController {
  if ([_rewardedAd isRewardedLoaded]) {
    [_rewardedAd show];
  } else {
    NSError *error = SampleCustomEventErrorWithCodeAndDescription(
        SampleCustomEventErrorAdNotLoaded,
        [NSString stringWithFormat:
                      @"The rewarded ad failed to present because the ad was not loaded."]);
    [_adEventDelegate didFailToPresentWithError:error]
  }
}

Meneruskan peristiwa mediasi ke Google Mobile Ads SDK

Setelah Anda memanggil GADMediationRewardedLoadCompletionHandler dengan iklan yang dimuat, objek delegasi GADMediationRewardedAdEventDelegate yang ditampilkan kemudian dapat digunakan oleh adaptor untuk meneruskan peristiwa presentasi dari SDK pihak ketiga ke Google Mobile Ads SDK. Class SampleCustomEventRewarded menerapkan protokol SampleRewardedAdDelegate untuk meneruskan callback dari contoh jaringan iklan ke Google Mobile Ads SDK.

Peristiwa kustom Anda harus meneruskan callback ini sebanyak mungkin, sehingga aplikasi Anda menerima peristiwa yang setara ini dari Google Mobile Ads SDK. Berikut adalah contoh penggunaan callback:

Swift

func rewardedAdDidPresent(_ rewarded: SampleRewardedAd) {
  delegate?.willPresentFullScreenVideo()
  delegate?.didStartVideo()
}

func rewardedAdUserDidEarnReward(_ rewarded: SampleRewardedAd) {
  GADAdReward aReward = GADAdReward("", rewarded)
  delegate.didRewardUser()
}

Objective-C

- (void)rewardedAdDidPresent:(SampleRewardedAd *)rewardedAd {
  [_adEventDelegate willPresentFullScreenView];
  [_adEventDelegate didStartVideo];
}

- (void)rewardedAd:(nonnull SampleRewardedAd *)rewardedAd
    userDidEarnReward:(NSUInteger)reward {
  GADAdReward *aReward = [[GADAdReward alloc]
      initWithRewardType:@""
            rewardAmount:[NSDecimalNumber numberWithUnsignedInt:reward]];
  [_adEventDelegate didRewardUserWithReward];
}

Ini melengkapi implementasi peristiwa kustom untuk iklan reward. Contoh lengkap tersedia di GitHub. Anda dapat menggunakannya dengan jaringan iklan yang sudah didukung atau mengubahnya untuk menampilkan iklan reward peristiwa kustom.
