リワード広告のカスタム イベント
コレクションでコンテンツを整理
必要に応じて、コンテンツの保存と分類を行います。
前提条件
カスタム イベントのセットアップを完了します。
リワード広告をリクエストする
ウォーターフォール メディエーション チェーンでカスタム イベント広告申込情報に到達すると、カスタム イベントの作成時に指定したクラス名で loadRewarded:adConfiguration:completionHandler: メソッドが呼び出されます。この場合、メソッドは SampleCustomEvent
にあり、loadRewarded:adConfiguration:completionHandler:
で SampleCustomEventRewarded
を呼び出します。
リワード広告をリクエストするには、GADMediationAdapter
と loadRewarded:adConfiguration:completionHandler:
を実装するクラスを作成または変更します。GADMediationAdapter
を拡張するクラスがすでに存在する場合は、そこに loadRewarded:adConfiguration:completionHandler:
を実装します。また、GADMediationRewardedAd
を実装するための新しいクラスを作成します。
この例では、SampleCustomEvent
が GADMediationAdapter
インターフェースを実装し、その後 SampleCustomEventRewarded
にデリゲートします。
Swift
import GoogleMobileAds
class SampleCustomEvent: NSObject, MediationAdapter {
fileprivate var rewardedAd: SampleCustomEventRewarded?
...
func loadRewarded(
for adConfiguration: MediationRewardedAdConfiguration,
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
の役割は次のとおりです。
アド マネージャーの管理画面で定義されたオプション パラメータは、広告構成に含まれます。このパラメータには adConfiguration.credentials.settings[@"parameter"]
を介してアクセスできます。このパラメータは通常、広告オブジェクトをインスタンス化する際に広告ネットワーク SDK が要求する広告ユニット ID です。
Swift
class SampleCustomEventRewarded: NSObject, MediationRewardedAd {
/// The Sample Ad Network rewarded ad.
var nativeAd: SampleRewarded?
/// The ad event delegate to forward ad rendering events to Google Mobile Ads SDK.
var delegate: MediationRewardedAdEventDelegate?
/// Completion handler called after ad load.
var completionHandler: GADMediationRewardedLoadCompletionHandler?
func loadRewarded(
for adConfiguration: MediationRewardedAdConfiguration,
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 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];
}
広告の取得が成功した場合もエラーが発生した場合も、GADMediationRewardedLoadCompletionHandler
を呼び出すことになります。成功した場合は、GADMediationRewardedAd
を実装するクラスを、エラー パラメータに nil
値を指定して渡します。失敗した場合は、発生したエラーを渡します。
通常、これらのメソッドは、アダプタが実装するサードパーティ SDK のコールバック内に実装されます。この例では、関連するコールバックを含む SampleRewardedAdDelegate
が「Sample SDK」に含まれています。
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
では、広告を表示する present(viewController:)
メソッドを実装する必要があります。
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]
}
}
メディエーション イベントを Google Mobile Ads SDK に転送する
読み込まれた広告で GADMediationRewardedLoadCompletionHandler
を呼び出した後、返された GADMediationRewardedAdEventDelegate
デリゲート オブジェクトをアダプタが使用することにより、プレゼンテーション イベントをサードパーティ SDK から Google Mobile Ads SDK に転送できます。SampleCustomEventRewarded
クラスは、サンプル広告ネットワークから Google Mobile Ads SDK にコールバックを転送するために SampleRewardedAdDelegate
プロトコルを実装します。
カスタム イベントには、こうしたコールバックを可能な限り漏れなく転送させましょう。これにより、アプリは同等イベントを Google Mobile Ads SDK から受け取ることができます。コールバックの使用例を以下に示します。
Swift
func rewardedAdDidPresent(_ rewarded: SampleRewardedAd) {
delegate?.willPresentFullScreenVideo()
delegate?.didStartVideo()
}
func rewardedAdUserDidEarnReward(_ rewarded: SampleRewardedAd) {
AdReward aReward = AdReward("", 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];
}
これで、リワード広告のカスタム イベントの実装が完了しました。サンプル全体は GitHub で入手できます。このサンプルは、すでにサポートされている広告ネットワークで使用することができます。また、変更を加えてカスタム イベント リワード広告を表示することもできます。

In this case,\nthat method is in `SampleCustomEvent`, which then calls\nthe `loadRewarded:adConfiguration:completionHandler:` method in\n`SampleCustomEventRewarded`.\n\nTo request a rewarded ad, create or modify a class that implements\n`GADMediationAdapter` and `loadRewarded:adConfiguration:completionHandler:`. If\na class that extends `GADMediationAdapter` already exists, implement\n`loadRewarded:adConfiguration:completionHandler:` there. Additionally,\ncreate a new class to implement `GADMediationRewardedAd`.\n\nIn our custom event example,\n[`SampleCustomEvent`](//github.com/googleads/googleads-mobile-ios-mediation/blob/main/example/CustomEvent/SampleCustomEvent.m) implements\nthe `GADMediationAdapter` interface and then delegates to\n`SampleCustomEventRewarded`. \n\nSwift \n\n```swift\nimport GoogleMobileAds\n\nclass SampleCustomEvent: NSObject, MediationAdapter {\n\n fileprivate var rewardedAd: SampleCustomEventRewarded?\n ...\n\n func loadRewarded(\n for adConfiguration: MediationRewardedAdConfiguration,\n completionHandler: @escaping GADMediationRewardedLoadCompletionHandler\n ) {\n self.rewardedAd = SampleCustomEventRewarded()\n self.rewardedAd?.loadRewarded(\n for: adConfiguration, completionHandler: completionHandler)\n }\n}\n```\n\nObjective-C \n\n```objective-c\n#import \"SampleCustomEvent.h\"\n\n@implementation SampleCustomEvent\n...\n\nSampleCustomEventRewarded *sampleRewarded;\n\n- (void)loadRewardedForAdConfiguration:\n (GADMediationRewardedAdConfiguration *)adConfiguration\n completionHandler:\n (GADMediationRewardedLoadCompletionHandler)\n completionHandler {\n sampleRewarded = [[SampleCustomEventRewarded alloc] init];\n [sampleRewarded loadRewardedForAdConfiguration:adConfiguration\n completionHandler:completionHandler];\n}\n```\n\n`SampleCustomEventRewarded` is responsible for the following tasks:\n\n- Loading the rewarded ad.\n\n- Implementing the `GADMediationRewardedAd` protocol.\n\n- Receiving and reporting ad event callbacks to Google Mobile Ads SDK.\n\nThe optional parameter defined in the Ad Manager UI is\nincluded in the ad configuration.\nThe parameter can be accessed through\n`adConfiguration.credentials.settings[@\"parameter\"]`. This parameter is\ntypically an ad unit identifier that an ad network SDK requires when\ninstantiating an ad object. \n\nSwift \n\n```swift\nclass SampleCustomEventRewarded: NSObject, MediationRewardedAd {\n /// The Sample Ad Network rewarded ad.\n var nativeAd: SampleRewarded?\n\n /// The ad event delegate to forward ad rendering events to Google Mobile Ads SDK.\n var delegate: MediationRewardedAdEventDelegate?\n\n /// Completion handler called after ad load.\n var completionHandler: GADMediationRewardedLoadCompletionHandler?\n\n func loadRewarded(\n for adConfiguration: MediationRewardedAdConfiguration,\n completionHandler: @escaping GADMediationRewardedLoadCompletionHandler\n ) {\n rewarded = SampleRewarded.init(\n adUnitID: adConfiguration.credentials.settings[\"parameter\"] as?

In the event of\nsuccess, pass through the class that implements `GADMediationRewardedAd`\nwith a `nil` value for the error parameter; in the event of failure, pass\nthrough the error you encountered.\n\nTypically, these methods are implemented inside callbacks from the\nthird-party SDK your adapter implements. For this example, the Sample SDK\nhas a `SampleRewardedAdDelegate` with relevant callbacks: \n\nSwift \n\n```swift\nfunc rewardedDidLoad(_ interstitial: SampleRewarded) {\n if let handler = completionHandler {\n delegate = handler(self, nil)\n }\n}\n\nfunc rewarded(\n rewarded: SampleRewarded, didFailToLoadAdWith errorCode: SampleErrorCode\n) {\n let error =\n SampleCustomEventUtils.SampleCustomEventErrorWithCodeAndDescription(\n code: SampleCustomEventErrorCode\n .SampleCustomEventErrorAdLoadFailureCallback,\n description:\n \"Sample SDK returned an ad load failure callback with error code: \\(errorCode)\"\n )\n if let handler = completionHandler {\n delegate = handler(nil, error)\n }\n}\n```\n\nObjective-C \n\n```objective-c\n- (void)rewardedDidLoad:(SampleRewarded *)rewarded {\n _adEventDelegate = _loadCompletionHandler(self, nil);\n}\n\n- (void)rewarded:(SampleInterstitial *)rewarded\n didFailToLoadAdWithErrorCode:(SampleErrorCode)errorCode {\n NSError *error = SampleCustomEventErrorWithCodeAndDescription(\n SampleCustomEventErrorAdLoadFailureCallback,\n [NSString stringWithFormat:@\"Sample SDK returned an ad load failure \"\n @\"callback with error code: %@\",\n errorCode]);\n _adEventDelegate = _loadCompletionHandler(nil, error);\n}\n```\n\n`GADMediationrewardedAd` requires implementing a `present(viewController:)`\nmethod to display the ad: \n\nSwift \n\n```swift\nfunc present(from viewController: UIViewController) {\n if let rewarded = rewarded, rewarded.isRewardedLoaded {\n rewarded.show()\n }\n}\n```\n\nObjective-C \n\n```objective-c\n- (void)presentFromViewController:(UIViewController *)viewController {\n if ([_rewardedAd isRewardedLoaded]) {\n [_rewardedAd show];\n } else {\n NSError *error = SampleCustomEventErrorWithCodeAndDescription(\n SampleCustomEventErrorAdNotLoaded,\n [NSString stringWithFormat:\n @\"The rewarded ad failed to present because the ad was not loaded.\"]);\n [_adEventDelegate didFailToPresentWithError:error]\n }\n}\n```\n\nForward mediation events to Google Mobile Ads SDK\n\nOnce you've called `GADMediationRewardedLoadCompletionHandler` with a loaded\nad, the returned `GADMediationRewardedAdEventDelegate` delegate object can\nthen be used by the adapter to forward presentation events from the third-party\nSDK to Google Mobile Ads SDK. The `SampleCustomEventRewarded` class\nimplements the `SampleRewardedAdDelegate` protocol to forward callbacks from\nthe sample ad network to Google Mobile Ads SDK.\n\nIt's important that your custom event forwards as many of these callbacks as\npossible, so that your app receives these equivalent events from Google Mobile Ads SDK.\nHere's an example of using callbacks: \n\nSwift \n\n```swift\nfunc rewardedAdDidPresent(_ rewarded: SampleRewardedAd) {\n delegate?.willPresentFullScreenVideo()\n delegate?.didStartVideo()\n}\n\nfunc rewardedAdUserDidEarnReward(_ rewarded: SampleRewardedAd) {\n AdReward aReward = AdReward(\"\", rewarded)\n delegate.didRewardUser()\n}\n```\n\nObjective-C \n\n```objective-c\n- (void)rewardedAdDidPresent:(SampleRewardedAd *)rewardedAd {\n [_adEventDelegate willPresentFullScreenView];\n [_adEventDelegate didStartVideo];\n}\n\n- (void)rewardedAd:(nonnull SampleRewardedAd *)rewardedAd\n userDidEarnReward:(NSUInteger)reward {\n GADAdReward *aReward = [[GADAdReward alloc]\n initWithRewardType:@\"\"\n rewardAmount:[NSDecimalNumber numberWithUnsignedInt:reward]];\n [_adEventDelegate didRewardUserWithReward];\n}\n```\n\nThis completes the custom events implementation for rewarded ads. The full\nexample is available on\n[GitHub](//github.com/googleads/googleads-mobile-ios-mediation/tree/master/example/CustomEvent).\nYou can use it with an ad network that is already supported or modify it to\ndisplay custom event rewarded ads."]]
