طلب إعلان بانر
عند الوصول إلى عنصر سعر الحدث المخصّص في سلسلة توسّط العرض الإعلاني بدون انقطاع، يتم استدعاء الطريقة loadBanner:adConfiguration:completionHandler: في اسم الفئة الذي قدّمته عند إنشاء حدث مخصّص. في هذه الحالة، تكون الطريقة في SampleCustomEvent، والتي تستدعي بعد ذلك الطريقة loadBanner:adConfiguration:completionHandler: في SampleCustomEventBanner.
لطلب إعلان بانر، أنشئ أو عدِّل فئة تنفّذ
GADMediationAdapter وloadBanner:adConfiguration:completionHandler:. إذا كان هناك صف
يمتد إلى GADMediationAdapter، نفِّذ
loadBanner:adConfiguration:completionHandler: هناك. بالإضافة إلى ذلك، أنشئ فئة جديدة لتنفيذ GADMediationBannerAd.
في مثال الحدث المخصّص،
تنفّذ SampleCustomEvent الواجهة GADMediationAdapter ثم تفوّض إلى
SampleCustomEventBanner.
Swift
import GoogleMobileAds
class SampleCustomEvent: NSObject, MediationAdapter {
fileprivate var bannerAd: SampleCustomEventBanner?
...
func loadBanner(
for adConfiguration: MediationBannerAdConfiguration,
completionHandler: @escaping GADMediationBannerLoadCompletionHandler
) {
self.bannerAd = SampleCustomEventBanner()
self.bannerAd?.loadBanner(
for: adConfiguration, completionHandler: completionHandler)
}
}
Objective-C
#import "SampleCustomEvent.h"
@implementation SampleCustomEvent
...
SampleCustomEventBanner *sampleBanner;
- (void)loadBannerForAdConfiguration:
(GADMediationBannerAdConfiguration *)adConfiguration
completionHandler:(GADMediationBannerLoadCompletionHandler)
completionHandler {
sampleBanner = [[SampleCustomEventBanner alloc] init];
[sampleBanner loadBannerForAdConfiguration:adConfiguration
completionHandler:completionHandler];
}
يتحمّل "SampleCustomEventBanner" مسؤولية المهام التالية:
تحميل إعلان البانر واستدعاء طريقة GADMediationBannerLoadCompletionHandler مرة واحدة بعد اكتمال عملية التحميل
تنفيذ بروتوكول GADMediationBannerAd
تلقّي عمليات معاودة الاتصال بأحداث الإعلانات وإعداد تقارير عنها إلى حزمة "SDK لإعلانات Google على الأجهزة الجوّالة"
يتم تضمين المَعلمة الاختيارية المحدّدة في واجهة مستخدم "مدير إعلانات Google" في إعدادات الإعلان.
يمكن الوصول إلى المَعلمة من خلال
adConfiguration.credentials.settings[@"parameter"]. عادةً ما تكون هذه المَعلمة معرّف وحدة إعلانية تتطلّبه حزمة SDK لشبكة إعلانية عند إنشاء مثيل لكائن إعلان.
Swift
class SampleCustomEventBanner: NSObject, MediationBannerAd {
/// The Sample Ad Network banner ad.
var bannerAd: SampleBanner?
/// The ad event delegate to forward ad rendering events to the Google Mobile Ads SDK.
var delegate: MediationBannerAdEventDelegate?
/// Completion handler called after ad load
var completionHandler: GADMediationBannerLoadCompletionHandler?
func loadBanner(
for adConfiguration: MediationBannerAdConfiguration,
completionHandler: @escaping GADMediationBannerLoadCompletionHandler
) {
// Create the bannerView with the appropriate size.
let adSize = adConfiguration.adSize
bannerAd = SampleBanner(
frame: CGRect(x: 0, y: 0, width: adSize.size.width, height: adSize.size.height))
bannerAd?.delegate = self
bannerAd?.adUnit = adConfiguration.credentials.settings["parameter"] as? String
let adRequest = SampleAdRequest()
adRequest.testMode = adConfiguration.isTestRequest
self.completionHandler = completionHandler
bannerAd?.fetchAd(adRequest)
}
}
Objective-C
#import "SampleCustomEventBanner.h"
@interface SampleCustomEventBanner () <SampleBannerAdDelegate,
GADMediationBannerAd> {
/// The sample banner ad.
SampleBanner *_bannerAd;
/// The completion handler to call when the ad loading succeeds or fails.
GADMediationBannerLoadCompletionHandler _loadCompletionHandler;
/// The ad event delegate to forward ad rendering events to the Google Mobile
/// Ads SDK.
id <GADMediationBannerAdEventDelegate> _adEventDelegate;
}
@end
@implementation SampleCustomEventBanner
- (void)loadBannerForAdConfiguration:
(GADMediationBannerAdConfiguration *)adConfiguration
completionHandler:(GADMediationBannerLoadCompletionHandler)
completionHandler {
__block atomic_flag completionHandlerCalled = ATOMIC_FLAG_INIT;
__block GADMediationBannerLoadCompletionHandler originalCompletionHandler =
[completionHandler copy];
_loadCompletionHandler = ^id<GADMediationBannerAdEventDelegate>(
_Nullable id<GADMediationBannerAd> ad, NSError *_Nullable error) {
// Only allow completion handler to be called once.
if (atomic_flag_test_and_set(&completionHandlerCalled)) {
return nil;
}
id<GADMediationBannerAdEventDelegate> 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"];
_bannerAd = [[SampleBanner alloc]
initWithFrame:CGRectMake(0, 0, adConfiguration.adSize.size.width,
adConfiguration.adSize.size.height)];
_bannerAd.adUnit = adUnit;
_bannerAd.delegate = self;
SampleAdRequest *adRequest = [[SampleAdRequest alloc] init];
adRequest.testMode = adConfiguration.isTestRequest;
[_bannerAd fetchAd:adRequest];
}
سواء تم جلب الإعلان بنجاح أو حدث خطأ، عليك استدعاء GADMediationBannerLoadCompletionHandler. في حال النجاح، مرِّر الفئة التي تنفّذ GADMediationBannerAd مع قيمة nil
لمَعلمة الخطأ. وفي حال التعذّر، مرِّر الخطأ الذي
واجهته.
عادةً، يتم تنفيذ هذه الطرق داخل عمليات ردّ الاتصال من حزمة تطوير البرامج (SDK) التابعة لجهة خارجية التي ينفّذها المحوّل. في هذا المثال، تحتوي حزمة تطوير البرامج (SDK) النموذجية على SampleBannerAdDelegate مع عمليات رد اتصال ذات صلة:
Swift
func bannerDidLoad(_ banner: SampleBanner) {
if let handler = completionHandler {
delegate = handler(self, nil)
}
}
func banner(
_ banner: SampleBanner, 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)bannerDidLoad:(SampleBanner *)banner {
_adEventDelegate = _loadCompletionHandler(self, nil);
}
- (void)banner:(SampleBanner *)banner
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);
}
يتطلّب GADMediationBannerAd تنفيذ السمة UIView:
Swift
var view: UIView {
return bannerAd ?? UIView()
}
Objective-C
- (nonnull UIView *)view {
return _bannerAd;
}
بعد طلب GADMediationBannerLoadCompletionHandler باستخدام إعلان تم تحميله، يمكن للمحوّل استخدام عنصر تفويض GADMediationBannerAdEventDelegate الذي تم عرضه لإعادة توجيه أحداث العرض من حزمة SDK التابعة لجهة خارجية إلى حزمة SDK لإعلانات Google على الأجهزة الجوّالة. تنفّذ الفئة SampleCustomEventBanner البروتوكول SampleBannerAdDelegate لإعادة توجيه عمليات رد الاتصال من شبكة الإعلانات النموذجية إلى حزمة تطوير البرامج (SDK) لإعلانات Google على الأجهزة الجوّالة.
من المهم أن يعيد توجيه الحدث المخصّص أكبر عدد ممكن من عمليات معاودة الاتصال هذه، كي يتلقّى تطبيقك الأحداث المكافئة من حزمة SDK لإعلانات Google على الأجهزة الجوّالة. في ما يلي مثال على استخدام عمليات معاودة الاتصال:
Swift
func bannerWillLeaveApplication(_ banner: SampleBanner) {
delegate?.reportClick()
}
Objective-C
- (void)bannerWillLeaveApplication:(SampleBanner *)banner {
[_adEventDelegate reportClick];
}
بهذا تكون قد أكملت عملية تنفيذ الأحداث المخصّصة لـ "إعلانات البانر". يتوفّر المثال الكامل على GitHub.
يمكنك استخدامها مع شبكة إعلانية متوافقة أو تعديلها لعرض إعلانات بانر للأحداث المخصّصة.

The `loadBanner:` method within this class fetches the ad, and then invokes a completion handler (`GADMediationBannerLoadCompletionHandler`) whether loading succeeds or fails, passing the banner ad or an error, respectively. Finally, use `GADMediationBannerAdEventDelegate` to forward presentation events.\n"],null,["Prerequisites\n\nComplete the [custom events setup](/ad-manager/mobile-ads-sdk/ios/custom-events/setup).\n\nRequest a banner ad\n\nWhen the custom event line item is reached in the waterfall mediation chain,\nthe `loadBanner:adConfiguration:completionHandler:` method is called on the\nclass name you provided when [creating a custom\nevent](/ad-manager/mobile-ads-sdk/ios/custom-events/setup#create). In this case,\nthat method is in `SampleCustomEvent`, which then calls\nthe `loadBanner:adConfiguration:completionHandler:` method in\n`SampleCustomEventBanner`.\n\nTo request a banner ad, create or modify a class that implements\n`GADMediationAdapter` and `loadBanner:adConfiguration:completionHandler:`. If a\nclass that extends `GADMediationAdapter` already exists, implement\n`loadBanner:adConfiguration:completionHandler:` there. Additionally, create a\nnew class to implement `GADMediationBannerAd`.\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`SampleCustomEventBanner`. \n\nSwift \n\n```swift\nimport GoogleMobileAds\n\nclass SampleCustomEvent: NSObject, MediationAdapter {\n\n fileprivate var bannerAd: SampleCustomEventBanner?\n ...\n\n func loadBanner(\n for adConfiguration: MediationBannerAdConfiguration,\n completionHandler: @escaping GADMediationBannerLoadCompletionHandler\n ) {\n self.bannerAd = SampleCustomEventBanner()\n self.bannerAd?.loadBanner(\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\nSampleCustomEventBanner *sampleBanner;\n\n- (void)loadBannerForAdConfiguration:\n (GADMediationBannerAdConfiguration *)adConfiguration\n completionHandler:(GADMediationBannerLoadCompletionHandler)\n completionHandler {\n sampleBanner = [[SampleCustomEventBanner alloc] init];\n [sampleBanner loadBannerForAdConfiguration:adConfiguration\n completionHandler:completionHandler];\n}\n```\n\n`SampleCustomEventBanner` is responsible for the following tasks:\n\n- Loading the banner ad and invoking a\n [`GADMediationBannerLoadCompletionHandler`](/ad-manager/mobile-ads-sdk/ios/api/reference/Protocols/GADMediationAdapter) method once\n loading completes.\n\n- Implementing the `GADMediationBannerAd` protocol.\n\n- Receiving and reporting ad event callbacks to the 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 SampleCustomEventBanner: NSObject, MediationBannerAd {\n /// The Sample Ad Network banner ad.\n var bannerAd: SampleBanner?\n\n /// The ad event delegate to forward ad rendering events to the Google Mobile Ads SDK.\n var delegate: MediationBannerAdEventDelegate?\n\n /// Completion handler called after ad load\n var completionHandler: GADMediationBannerLoadCompletionHandler?\n\n func loadBanner(\n for adConfiguration: MediationBannerAdConfiguration,\n completionHandler: @escaping GADMediationBannerLoadCompletionHandler\n ) {\n // Create the bannerView with the appropriate size.\n let adSize = adConfiguration.adSize\n bannerAd = SampleBanner(\n frame: CGRect(x: 0, y: 0, width: adSize.size.width, height: adSize.size.height))\n bannerAd?.delegate = self\n bannerAd?.adUnit = adConfiguration.credentials.settings[\"parameter\"] as? String\n let adRequest = SampleAdRequest()\n adRequest.testMode = adConfiguration.isTestRequest\n self.completionHandler = completionHandler\n bannerAd?.fetchAd(adRequest)\n }\n}\n```\n\nObjective-C \n\n```objective-c\n#import \"SampleCustomEventBanner.h\"\n\n@interface SampleCustomEventBanner () \u003cSampleBannerAdDelegate,\n GADMediationBannerAd\u003e {\n /// The sample banner ad.\n SampleBanner *_bannerAd;\n\n /// The completion handler to call when the ad loading succeeds or fails.\n GADMediationBannerLoadCompletionHandler _loadCompletionHandler;\n\n /// The ad event delegate to forward ad rendering events to the Google Mobile\n /// Ads SDK.\n id \u003cGADMediationBannerAdEventDelegate\u003e _adEventDelegate;\n}\n@end\n\n@implementation SampleCustomEventBanner\n\n- (void)loadBannerForAdConfiguration:\n (GADMediationBannerAdConfiguration *)adConfiguration\n completionHandler:(GADMediationBannerLoadCompletionHandler)\n completionHandler {\n __block atomic_flag completionHandlerCalled = ATOMIC_FLAG_INIT;\n __block GADMediationBannerLoadCompletionHandler originalCompletionHandler =\n [completionHandler copy];\n\n _loadCompletionHandler = ^id\u003cGADMediationBannerAdEventDelegate\u003e(\n _Nullable id\u003cGADMediationBannerAd\u003e ad, NSError *_Nullable error) {\n // Only allow completion handler to be called once.\n if (atomic_flag_test_and_set(&completionHandlerCalled)) {\n return nil;\n }\n\n id\u003cGADMediationBannerAdEventDelegate\u003e delegate = nil;\n if (originalCompletionHandler) {\n // Call original handler and hold on to its return value.\n delegate = originalCompletionHandler(ad, error);\n }\n\n // Release reference to handler.

In the event of success,\npass through the class that implements `GADMediationBannerAd` with a `nil` value\nfor the error parameter; in the event of failure, pass through the error you\nencountered.\n\nTypically, these methods are implemented inside callbacks from the\nthird-party SDK your adapter implements. For this example, the Sample SDK\nhas a `SampleBannerAdDelegate` with relevant callbacks: \n\nSwift \n\n```swift\nfunc bannerDidLoad(_ banner: SampleBanner) {\n if let handler = completionHandler {\n delegate = handler(self, nil)\n }\n}\n\nfunc banner(\n _ banner: SampleBanner, didFailToLoadAdWith errorCode: SampleErrorCode\n) {\n let error =\n SampleCustomEventUtilsSwift.SampleCustomEventErrorWithCodeAndDescription(\n code: SampleCustomEventErrorCodeSwift\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)bannerDidLoad:(SampleBanner *)banner {\n _adEventDelegate = _loadCompletionHandler(self, nil);\n}\n\n- (void)banner:(SampleBanner *)banner\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`GADMediationBannerAd` requires implementing a `UIView` property: \n\nSwift \n\n```swift\nvar view: UIView {\n return bannerAd ?? UIView()\n}\n```\n\nObjective-C \n\n```objective-c\n- (nonnull UIView *)view {\n return _bannerAd;\n}\n```\n\nForward mediation events to the Google Mobile Ads SDK\n\nOnce you've called `GADMediationBannerLoadCompletionHandler` with a loaded ad,\nthe returned `GADMediationBannerAdEventDelegate` delegate object can then be\nused by the adapter to forward presentation events from the third-party SDK to\nthe Google Mobile Ads SDK. The `SampleCustomEventBanner` class implements the\n`SampleBannerAdDelegate` protocol to forward callbacks from the sample ad\nnetwork to the 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 the Google\nMobile Ads SDK. Here's an example of using callbacks: \n\nSwift \n\n```swift\nfunc bannerWillLeaveApplication(_ banner: SampleBanner) {\n delegate?.reportClick()\n}\n```\n\nObjective-C \n\n```objective-c\n- (void)bannerWillLeaveApplication:(SampleBanner *)banner {\n [_adEventDelegate reportClick];\n}\n```\n\nThis completes the custom events implementation for banner ads. The full example\nis available on\n[GitHub](//github.com/googleads/googleads-mobile-ios-mediation/tree/main/example/CustomEvent).\nYou can use it with an ad network that is already supported or modify it to\ndisplay custom event banner ads."]]
