Peristiwa kustom iklan interstisial

Prasyarat

Selesaikan penyiapan peristiwa kustom.

Meminta iklan interstisial

Saat item baris peristiwa kustom dijangkau dalam rantai mediasi waterfall,the loadInterstitial:adConfiguration:completionHandler: method dipanggil nama class yang Anda berikan saat membuat peristiwa kustom. Dalam hal ini, metode tersebut ada di SampleCustomEvent, yang kemudian memanggil the loadInterstitial:adConfiguration:completionHandler: method di SampleCustomEventInterstitial.

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

Dalam contoh peristiwa kustom, SampleCustomEvent mengimplementasikanthe GADMediationAdapter interface , lalu mendelegasikan keSampleCustomEventInterstitial.

Swift

import GoogleMobileAds

class SampleCustomEvent: NSObject, GADMediationAdapter {

  fileprivate var interstitialAd: SampleCustomEventInterstitial?
  ...

  func loadInterstitial(
    for adConfiguration: GADMediationInterstitialAdConfiguration,
    completionHandler: @escaping GADMediationInterstitialLoadCompletionHandler
  ) {
    self.interstitialAd = SampleCustomEventInterstitial()
    self.interstitialAd?.loadInterstitial(
      for: adConfiguration, completionHandler: completionHandler)
  }
}

Objective-C

#import "SampleCustomEvent.h"

@implementation SampleCustomEvent

SampleCustomEventInterstitial *sampleInterstitial;

- (void)loadInterstitialForAdConfiguration:
            (GADMediationInterstitialAdConfiguration *)adConfiguration
                         completionHandler:
                             (GADMediationInterstitialLoadCompletionHandler)
                                 completionHandler {
  sampleInterstitial = [[SampleCustomEventInterstitial alloc] init];
  [sampleInterstitial loadInterstitialForAdConfiguration:adConfiguration
                                       completionHandler:completionHandler];
}

SampleCustomEventInterstitial bertanggung jawab atas tugas berikut:

• Memuat iklan interstisial dan memanggilGADMediationInterstitialAdLoadCompletionHandler method setelah pemuatan selesai

• Menerapkan GADMediationInterstitialAd protocol

• Menerima dan melaporkan callback peristiwa iklan ke Google Mobile Ads SDK

Parameter opsional yang ditentukan dalam AdMob UI diteruskan ke peristiwa kustom Anda sebagai bagian dari the loadInterstitial:adConfiguration:completionHandler: method. Parameter dapat diakses melalui adConfiguration.credentials.settings[@"parameter"]. Parameter ini biasanya berupa ID unit iklan yang diperlukan SDK jaringan iklan saat membuat instance objek iklan.

Swift

import GoogleMobileAds

class SampleCustomEventInterstitial: NSObject, GADMediationInterstitialAd {
  /// The Sample Ad Network interstitial ad.
  var interstitial: SampleInterstitial?

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

  var completionHandler: GADMediationInterstitialLoadCompletionHandler?

  func loadInterstitial(
    for adConfiguration: GADMediationInterstitialAdConfiguration,
    completionHandler: @escaping GADMediationInterstitialLoadCompletionHandler
  ) {
    interstitial = SampleInterstitial.init(
      adUnitID: adConfiguration.credentials.settings["parameter"] as? String)
    interstitial?.delegate = self
    let adRequest = SampleAdRequest()
    adRequest.testMode = adConfiguration.isTestRequest
    self.completionHandler = completionHandler
    interstitial?.fetchAd(adRequest)
  }

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

Objective-C

#import "SampleCustomEventInterstitial.h"

@interface SampleCustomEventInterstitial () <SampleInterstitialAdDelegate,
                                             GADMediationInterstitialAd> {
  /// The sample interstitial ad.
  SampleInterstitial *_interstitialAd;

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

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

- (void)loadInterstitialForAdConfiguration:
            (GADMediationInterstitialAdConfiguration *)adConfiguration
                         completionHandler:
                             (GADMediationInterstitialLoadCompletionHandler)
                                 completionHandler {
  __block atomic_flag completionHandlerCalled = ATOMIC_FLAG_INIT;
  __block GADMediationInterstitialLoadCompletionHandler
      originalCompletionHandler = [completionHandler copy];

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

    id<GADMediationInterstitialAdEventDelegate> 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"];
  _interstitialAd = [[SampleInterstitial alloc] initWithAdUnitID:adUnit];
  _interstitialAd.delegate = self;
  SampleAdRequest *adRequest = [[SampleAdRequest alloc] init];
  adRequest.testMode = adConfiguration.isTestRequest;
  [_interstitialAd fetchAd:adRequest];
}

Baik jika iklan berhasil diambil atau mengalami error, Anda akan memanggil GADMediationInterstitialLoadCompletionHandler. Jika berhasil, teruskan class yang menerapkan GADMediationInterstitialAd dengan nilai nil untuk parameter error; jika terjadi kegagalan, teruskan error yang Anda temui.

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

Swift

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

func interstitial(
  _ interstitial: SampleInterstitial,
  didFailToLoadAdWith errorCode: SampleErrorCode
) {
  let error =
    SampleCustomEventUtilsSwift.SampleCustomEventErrorWithCodeAndDescription(
      code: SampleCustomEventErrorCodeSwift
        .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)interstitialDidLoad:(SampleInterstitial *)interstitial {
  _adEventDelegate = _loadCompletionHandler(self, nil);
}

- (void)interstitial:(SampleInterstitial *)interstitial
    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);
}

GADMediationInterstitialAd mengharuskan penerapan metode present untuk menampilkan iklan:

Swift

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

Objective-C

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

Meneruskan peristiwa mediasi ke Google Mobile Ads SDK

Setelah Anda memanggil GADMediationInterstitialLoadCompletionHandler dengan iklan yang dimuat, objek delegasi GADMediationInterstitialAdEventDelegate yang ditampilkan dapat digunakan oleh adaptor untuk meneruskan peristiwa presentasi dari SDK pihak ketiga ke Google Mobile Ads SDK. Class SampleCustomEventInterstitial menerapkan protokol SampleInterstitialAdDelegate untuk meneruskan callback dari sampel jaringan iklan ke Google Mobile Ads SDK.

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

Swift

func interstitialWillPresentScreen(_ interstitial: SampleInterstitial) {
  delegate?.willPresentFullScreenView()
  delegate?.reportImpression()
}

func interstitialWillDismissScreen(_ interstitial: SampleInterstitial) {
  delegate?.willDismissFullScreenView()
}

func interstitialDidDismissScreen(_ interstitial: SampleInterstitial) {
  delegate?.didDismissFullScreenView()
}

func interstitialWillLeaveApplication(_ interstitial: SampleInterstitial) {
  delegate?.reportClick()
}

Objective-C

- (void)interstitialWillPresentScreen:(SampleInterstitial *)interstitial {
  [_adEventDelegate willPresentFullScreenView];
  [_adEventDelegate reportImpression];
}

- (void)interstitialWillDismissScreen:(SampleInterstitial *)interstitial {
  [_adEventDelegate willDismissFullScreenView];
}

- (void)interstitialDidDismissScreen:(SampleInterstitial *)interstitial {
  [_adEventDelegate didDismissFullScreenView];
}

- (void)interstitialWillLeaveApplication:(SampleInterstitial *)interstitial {
  [_adEventDelegate reportClick];
}

Tindakan ini menyelesaikan penerapan peristiwa kustom untuk iklan interstisial. Contoh lengkap tersedia di GitHub. Anda dapat menggunakannya dengan jaringan iklan yang sudah didukung atau mengubahnya untuk menampilkan iklan interstisial peristiwa kustom.
