当 Google 移动广告 SDK 初始化时,系统会针对在 Ad Manager 界面中为应用配置的所有受支持的第三方适配器和自定义事件调用 setUpWithConfiguration:completionHandler:。您可以使用此方法对自定义事件所需的第三方 SDK 执行任何必要的设置或初始化操作。
Swift
importGoogleMobileAdsclassSampleCustomEvent:NSObject,MediationAdapter{staticfuncsetUpWith(_configuration:MediationServerConfiguration,completionHandler:@escapingGADMediationAdapterSetUpCompletionBlock){// This is where you will initialize the SDK that this custom event is built// for. Upon finishing the SDK initialization, call the completion handler// with success.completionHandler(nil)}}
Objective-C
#import "SampleCustomEvent.h"@implementationSampleCustomEvent+(void)setUpWithConfiguration:(nonnullGADMediationServerConfiguration*)configurationcompletionHandler:(nonnullGADMediationAdapterSetUpCompletionBlock)completionHandler{// This is where you initialize the SDK that this custom event is built// for. Upon finishing the SDK initialization, call the completion handler// with success.completionHandler(nil);}
报告版本号
所有自定义事件都必须向
Google 移动广告 SDK
报告自定义事件适配器本身的版本,以及与该自定义事件对接的第三方 SDK 的版本。报告版本时使用的是 GADVersionNumber 对象:

See the instructions in\n\n[Create and manage yield\ngroups](//support.google.com/admanager/answer/7390828).\n\n\nYou need to supply the following:\n\nClass Name\n\n: The fully-qualified name of the class that implements the custom event\n adapter---for example,\n\n `SampleCustomEvent`; or if your class is implemented in Swift,\n `MediationExample.SampleCustomEventSwift`.\n\n Target name is required if you have multiple targets in your project or if\n the project name is different from the target name. With the target name, it\n would look like this: `appName_targetName.className`. In addition, remember\n to replace any non-alphanumeric characters such as dashes with underscores.\n [Example](//maximbilan.medium.com/ios-objective-c-project-nsclassfromstring-method-for-swift-classes-dbadb721723).\n\nLabel\n\n: A unique name defining the ad source.\n\nParameter\n\n: An optional string argument passed to your custom event adapter.\n\nImplement GADMediationAdapter\n\nThe first step to creating a custom event is implementing the\n`GADMediationAdapter` protocol as shown by the `SampleCustomEvent` class\nin [our example](//github.com/googleads/googleads-mobile-ios-mediation).\n\nIt is the responsibility of this class to receive messages from\nAd Manager and delegate the responsibility of creating\nthe correct ad format.\n\nInitialize the adapter\n\nWhen Google Mobile Ads SDK initializes,\n\n`setUpWithConfiguration:completionHandler:`\n\nis invoked on all supported third-party adapters and custom events configured\nfor the app within the Ad Manager UI.
