Peristiwa kustom iklan interstisial

Prasyarat

Meminta iklan interstisial

Saat item baris peristiwa kustom tercapai dalam rantai mediasi waterfall, the loadInterstitial:adConfiguration:completionHandler: method akan dipanggil pada 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 dalam SampleCustomEventInterstitial.

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

Dalam contoh peristiwa kustom kami, 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-tugas berikut:

Memuat iklan interstisial dan memanggil GADMediationInterstitialAdLoadCompletionHandler method setelah pemuatan selesai
Mengimplementasikan GADMediationInterstitialAd protocol
Menerima dan melaporkan callback peristiwa iklan ke Google Mobile Ads SDK

Parameter opsional yang ditentukan dalam UI Ad Manager disertakan dalam konfigurasi iklan. Parameter ini dapat diakses melalui adConfiguration.credentials.settings[@"parameter"]. Parameter ini biasanya merupakan 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 iklan berhasil diambil atau mengalami error, Anda akan memanggil GADMediationInterstitialLoadCompletionHandler. Jika berhasil, lewati class yang mengimplementasikan GADMediationInterstitialAd dengan nilai nil untuk parameter error; jika terjadi kegagalan, teruskan error yang Anda alami.

Biasanya, metode ini diimplementasikan di dalam callback dari SDK pihak ketiga yang diterapkan oleh adaptor Anda. Untuk contoh ini, SDK Sampel 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 memerlukan 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 kemudian dapat digunakan oleh adaptor untuk meneruskan peristiwa presentasi dari SDK pihak ketiga ke Google Mobile Ads SDK. Kelas SampleCustomEventInterstitial menerapkan protokol SampleInterstitialAdDelegate untuk meneruskan callback dari jaringan iklan contoh ke Google Mobile Ads SDK.

Peristiwa kustom Anda harus meneruskan callback ini sebanyak mungkin, agar aplikasi Anda menerima peristiwa yang setara 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];
}

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