Peristiwa kustom iklan interstisial

Prasyarat

Selesaikan penyiapan peristiwa kustom.

Meminta iklan interstisial

Saat item baris peristiwa kustom dijangkau dalam rantai mediasi waterfall, metode loadInterstitial:adConfiguration:completionHandler: dipanggil di nama kelas yang Anda berikan saat membuat peristiwa. Dalam kasus ini, metode tersebut berada di SampleCustomEvent, yang kemudian memanggil metode loadInterstitial:adConfiguration:completionHandler: di 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, SampleCustomEvent menerapkan antarmuka GADMediationAdapter, lalu didelegasikan ke SampleCustomEventInterstitial.

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)
  }
}

#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 memanggil GADMediationInterstitialAdLoadCompletionHandler setelah pemuatan selesai.

• Mengimplementasikan protokol GADMediationInterstitialAd.

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

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

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()
    }
  }
}

#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];
}

Apakah iklan berhasil diambil atau mengalami error, Anda akan memanggil GADMediationInterstitialLoadCompletionHandler. Jika terjadi berhasil, teruskan class yang mengimplementasikan GADMediationInterstitialAd dengan nilai nil untuk parameter error; jika terjadi kegagalan, teruskan kesalahan yang Anda alami.

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

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)
  }
}

- (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 agar dapat ditampilkan iklan:

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

- (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, objek delegasi GADMediationInterstitialAdEventDelegate yang ditampilkan dapat kemudian digunakan oleh adaptor untuk meneruskan kejadian presentasi dari Google Mobile Ads SDK. Class SampleCustomEventInterstitial menerapkan protokol SampleInterstitialAdDelegate untuk meneruskan callback dari jaringan iklan contoh ke Google Mobile Ads SDK.

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

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()
}

- (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. Lengkap contoh tersedia di GitHub. Anda dapat menggunakannya dengan jaringan iklan yang sudah didukung atau mengubahnya untuk menampilkan iklan interstisial peristiwa kustom.
