插頁式獎勵廣告是一種獎勵廣告格式，可在應用程式自然轉換時自動顯示這類廣告，向使用者提供獎勵。與獎勵廣告不同的是，插頁式獎勵廣告不需要等使用者確定選擇觀看即可放送。
必要條件
- Google Mobile Ads SDK 7.60.0 以上版本。
- 完成入門指南。
實作
整合插頁式獎勵廣告的主要步驟如下：
- 載入廣告
- [選用] 驗證 SSV 回呼
- 註冊回呼
- 顯示廣告並處理獎勵事件
載入廣告
您可以使用 GADRewardedInterstitialAd 類別的 load(adUnitID:request) 方法載入廣告。
Swift
import GoogleMobileAds
import UIKit
class ViewController: UIViewController {
private var rewardedInterstitialAd: GADRewardedInterstitialAd?
override func viewDidLoad() {
super.viewDidLoad()
Task {
do {
rewardedInterstitialAd = try await GADRewardedInterstitialAd.load(
withAdUnitID: "ca-app-pub-3940256099942544/6978759866", request: GADRequest())
} catch {
print("Failed to load rewarded interstitial ad with error: \(error.localizedDescription)")
}
}
}
}
SwiftUI
import GoogleMobileAds
class RewardedInterstitialViewModel: NSObject, ObservableObject,
GADFullScreenContentDelegate
{
@Published var coins = 0
private var rewardedInterstitialAd: GADRewardedInterstitialAd?
func loadAd() async {
do {
rewardedInterstitialAd = try await GADRewardedInterstitialAd.load(
withAdUnitID: "ca-app-pub-3940256099942544/6978759866", request: GADRequest())
rewardedInterstitialAd?.fullScreenContentDelegate = self
} catch {
print(
"Failed to load rewarded interstitial ad with error: \(error.localizedDescription)")
}
}
Objective-C
#import "ViewController.h"
@interface ViewController ()
@property(nonatomic, strong) GADRewardedInterstitialAd* rewardedInterstitialAd;
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
[GADRewardedInterstitialAd
loadWithAdUnitID:@"<var label='the ad unit ID'>ca-app-pub-3940256099942544/6978759866</var>"
request:[GADRequest request]
completionHandler:^(
GADRewardedInterstitialAd* _Nullable rewardedInterstitialAd,
NSError* _Nullable error) {
if (!error) {
self.rewardedInterstitialAd = rewardedInterstitialAd;
}
}
];
}
[選用] 驗證伺服器端驗證 (SSV) 回呼
如果應用程式需要在伺服器端驗證回呼中使用額外資料，則應使用獎勵廣告的客製資料功能。獎勵廣告物件上設定的任何字串值，都會傳遞至 SSV 回呼的 custom_data 查詢參數。如果未設定自訂資料值，SSV 回呼中就不會顯示 custom_data 查詢參數值。
以下程式碼範例示範如何在要求廣告前，在獎勵式插頁廣告物件上設定自訂資料。
Swift
do {
rewardedInterstitialAd = try await GADRewardedInterstitialAd.load(
withAdUnitID: "ca-app-pub-3940256099942544/6978759866", request: GADRequest())
let options = GADServerSideVerificationOptions()
options.customRewardString = "SAMPLE_CUSTOM_DATA_STRING"
rewardedInterstitialAd.serverSideVerificationOptions = options
} catch {
print("Rewarded ad failed to load with error: \(error.localizedDescription)")
}
Objective-C
[GADRewardedInterstitialAd
loadWithAdUnitID:@"ca-app-pub-3940256099942544/6978759866"
request:GADRequest
completionHandler:^(GADRewardedInterstitialAd *ad, NSError *error) {
if (error) {
// Handle Error
return;
}
self.rewardedInterstitialAd = ad;
GADServerSideVerificationOptions *options =
[[GADServerSideVerificationOptions alloc] init];
options.customRewardString = @"SAMPLE_CUSTOM_DATA_STRING";
ad.serverSideVerificationOptions = options;
}];
註冊回呼
為了接收簡報事件的通知，您必須導入 GADFullScreenContentDelegate 通訊協定，並指派給傳回廣告的 fullScreenContentDelegate 屬性。GADFullScreenContentDelegate 通訊協定會處理廣告呈現成功或失敗，以及廣告關閉時的回呼。下列程式碼顯示如何導入通訊協定，並將其指派給廣告：
Swift
import GoogleMobileAds
import UIKit
class ViewController: UIViewController, GADFullScreenContentDelegate {
private var rewardedInterstitialAd: GADRewardedInterstitialAd?
override func viewDidLoad() {
super.viewDidLoad()
Task {
do {
rewardedInterstitialAd = try await GADRewardedInterstitialAd.load(
withAdUnitID: "ca-app-pub-3940256099942544/6978759866", request: GADRequest())
self.rewardedInterstitialAd?.fullScreenContentDelegate = self
} catch {
print("Failed to load rewarded interstitial ad with error: \(error.localizedDescription)")
}
}
}
/// Tells the delegate that the ad failed to present full screen content.
func ad(_ ad: GADFullScreenPresentingAd, didFailToPresentFullScreenContentWithError error: Error) {
print("Ad did fail to present full screen content.")
}
/// Tells the delegate that the ad will present full screen content.
func adWillPresentFullScreenContent(_ ad: GADFullScreenPresentingAd) {
print("Ad will present full screen content.")
}
/// Tells the delegate that the ad dismissed full screen content.
func adDidDismissFullScreenContent(_ ad: GADFullScreenPresentingAd) {
print("Ad did dismiss full screen content.")
}
}
SwiftUI
將 fullScreenContentDelegate 屬性指派給傳回的廣告：
rewardedInterstitialAd?.fullScreenContentDelegate = self
實作通訊協定：
func adDidRecordImpression(_ ad: GADFullScreenPresentingAd) {
print("\(#function) called")
}
func adDidRecordClick(_ ad: GADFullScreenPresentingAd) {
print("\(#function) called")
}
func ad(
_ ad: GADFullScreenPresentingAd,
didFailToPresentFullScreenContentWithError error: Error
) {
print("\(#function) called")
}
func adWillPresentFullScreenContent(_ ad: GADFullScreenPresentingAd) {
print("\(#function) called")
}
func adWillDismissFullScreenContent(_ ad: GADFullScreenPresentingAd) {
print("\(#function) called")
}
func adDidDismissFullScreenContent(_ ad: GADFullScreenPresentingAd) {
print("\(#function) called")
// Clear the rewarded interstitial ad.
rewardedInterstitialAd = nil
}
Objective-C
@interface ViewController () <GADFullScreenContentDelegate>
@property(nonatomic, strong) GADRewardedInterstitialAd *rewardedInterstitialAd;
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.
[GADRewardedInterstitialAd
loadWithAdUnitID:@"ca-app-pub-3940256099942544/6978759866"
request:[GADRequest request]
completionHandler:^(
GADRewardedInterstitialAd *_Nullable rewardedInterstitialAd,
NSError *_Nullable error) {
if (!error) {
self.rewardedInterstitialAd = rewardedInterstitialAd;
self.rewardedInterstitialAd.fullScreenContentDelegate = self;
}
}];
}
/// Tells the delegate that the ad failed to present full screen content.
- (void)ad:(nonnull id<GADFullScreenPresentingAd>)ad
didFailToPresentFullScreenContentWithError:(nonnull NSError *)error {
NSLog(@"Ad did fail to present full screen content.");
}
/// Tells the delegate that the ad will present full screen content.
- (void)adWillPresentFullScreenContent:(nonnull id<GADFullScreenPresentingAd>)ad {
NSLog(@"Ad will present full screen content.");
}
/// Tells the delegate that the ad dismissed full screen content.
- (void)adDidDismissFullScreenContent:(nonnull id<GADFullScreenPresentingAd>)ad {
NSLog(@"Ad did dismiss full screen content.");
}
顯示廣告並處理獎勵事件
在呈現廣告時，您必須提供 GADUserDidEarnRewardHandler 物件，以便為使用者處理獎勵。
以下程式碼提供顯示獎勵插頁式廣告的最佳方法。
Swift
func show() {
guard let rewardedInterstitialAd = rewardedInterstitialAd else {
return print("Ad wasn't ready.")
}
// The UIViewController parameter is an optional.
rewardedInterstitialAd.present(fromRootViewController: nil) {
let reward = rewardedInterstitialAd.adReward
print("Reward received with currency \(reward.amount), amount \(reward.amount.doubleValue)")
// TODO: Reward the user.
}
}
SwiftUI
監聽檢視畫面中的 UI 事件，以便顯示廣告。
var rewardedInterstitialBody: some View {
// ...
}
.onChange(
of: showAd,
perform: { newValue in
if newValue {
viewModel.showAd()
}
}
)
在檢視模型中顯示插頁式獎勵廣告：
func showAd() {
guard let rewardedInterstitialAd = rewardedInterstitialAd else {
return print("Ad wasn't ready.")
}
rewardedInterstitialAd.present(fromRootViewController: nil) {
let reward = rewardedInterstitialAd.adReward
print("Reward amount: \(reward.amount)")
self.addCoins(reward.amount.intValue)
}
}
Objective-C
- (void)show {
// The UIViewController parameter is nullable.
[_rewardedInterstitialAd presentFromRootViewController:nil
userDidEarnRewardHandler:^{
GADAdReward *reward =
self.rewardedInterstitialAd.adReward;
// TODO: Reward the user.
}];
}
