瞭解詳情

IMA SDK 可讓您輕鬆將多媒體廣告整合至您的網站和應用程式。IMA SDK 可以 向任何 與 VAST 相容的廣告伺服器,並管理您應用程式中的廣告播放方式。使用 IMA 用戶端 SDK 您能掌控內容影片播放,而 SDK 會處理廣告播放。廣告在 獨立影片播放器位於應用程式內容影片播放器上方。

本指南說明如何將 IMA SDK 整合到簡易的影片播放器中 應用程式。如果您要檢視或繼續完成樣本 請下載 BasicExample: GitHub。

IMA 用戶端總覽

導入 IMA 用戶端需要四個主要 SDK 元件, 如本指南所示:

  • IMAAdDisplayContainer: 廣告顯示位置的容器物件。
  • IMAAdsLoader: 這個物件會請求廣告,以及處理廣告請求回應中的事件。除了 將一個廣告載入器執行個體化,以便在應用程式生命週期中重複使用。
  • IMAAdsRequest: 定義廣告請求的物件。廣告請求會指定 VAST 廣告代碼的網址,以及 額外參數,例如廣告尺寸。
  • IMAAdsManager: 包含回應廣告請求、控制廣告播放以及監聽廣告的物件 SDK 觸發的事件。

必要條件

開始之前,請先備妥以下項目:

1. 建立新的 Xcode 專案

在 Xcode 中,使用 Objective-C 或 Swift 建立新的 iOS 專案。使用 BasicExample 做為專案名稱。

2. 在 Xcode 專案中加入 IMA SDK

CocoaPods 是 Xcode 專案的依附元件管理工具,建議使用 方法。進一步瞭解如何安裝或使用 CocoaPods,請參閱 CocoaPods 說明文件。當您 已安裝 CocoaPods,請按照下列操作說明安裝 IMA SDK:

  1. 在與 BasicExample.xcodeproj 檔案相同的目錄中,建立文字 檔案,並新增以下設定:

    source 'https://github.com/CocoaPods/Specs.git'
    platform :ios, '14'
    target "BasicExample" do
      pod 'GoogleAds-IMA-iOS-SDK', '~> 3.23.0'
    end
    
  2. 從包含 Podfile 的目錄,執行 pod install --repo-update

  3. 開啟 BasicExample.xcworkspace 檔案,並確認該檔案包含兩個專案: BasicExamplePod (由 CocoaPods 安裝的依附元件)。

使用 Swift Package Manager 安裝 SDK

互動式媒體廣告 SDK 支援 Swift 套件 Manager,從 3.18.4 版開始。跟著 才能匯入 Swift 套件。

  1. 在 Xcode 中,前往 檔案 >新增套件...

  2. 在隨即顯示的提示中,搜尋 IMA SDK Swift 套件 GitHub 存放區:

    https://github.com/googleads/swift-package-manager-google-interactive-media-ads-ios
    
  3. 選取您要使用的 IMA SDK Swift 套件版本。 如要建立新專案,建議您使用直到下一個主要版本

完成後,Xcode 會解析套件依附元件 在背景中下載這些檔案進一步瞭解如何新增套件 依附元件,請參閱 Apple 的文章

手動下載並安裝 SDK

如果您不想使用 Swift Package Manager 或 CocoaPods,可以下載 IMA SDK 並 手動將其加入專案中。

3. 建立簡易影片播放器

首先,導入基本影片播放器。一開始,此播放器並未使用 IMA SDK,且尚未包含任何觸發播放的方法。

ViewController.m

Objective-C

#import "ViewController.h"

#import <AVKit/AVKit.h>

NSString *const kContentURLString =
    @"https://storage.googleapis.com/interactive-media-ads/media/stock.mp4";

@interface ViewController ()
@property(nonatomic) AVPlayerViewController *contentPlayerViewController;
@end

@implementation ViewController

- (void)viewDidLoad {
  [super viewDidLoad];
  self.view.backgroundColor = UIColor.blackColor;
  [self setupContentPlayer];
}

- (void)setupContentPlayer {
  // Create a content video player.
  NSURL *contentURL = [NSURL URLWithString:kContentURLString];
  AVPlayer *player = [AVPlayer playerWithURL:contentURL];
  self.contentPlayerViewController = [[AVPlayerViewController alloc] init];
  self.contentPlayerViewController.player = player;
  self.contentPlayerViewController.view.frame = self.view.bounds;

  // Attach content video player to view hierarchy.
  [self showContentPlayer];
}

// Add the content video player as a child view controller.
- (void)showContentPlayer {
  [self addChildViewController:self.contentPlayerViewController];
  self.contentPlayerViewController.view.frame = self.view.bounds;
  [self.view insertSubview:self.contentPlayerViewController.view atIndex:0];
  [self.contentPlayerViewController didMoveToParentViewController:self];
}

// Remove and detach the content video player.
- (void)hideContentPlayer {
  // The whole controller needs to be detached so that it doesn't capture events from the remote.
  [self.contentPlayerViewController willMoveToParentViewController:nil];
  [self.contentPlayerViewController.view removeFromSuperview];
  [self.contentPlayerViewController removeFromParentViewController];
}

@end
      

Swift

import AVFoundation
import UIKit

class ViewController: UIViewController {
  static let ContentURLString = "https://storage.googleapis.com/interactive-media-ads/media/stock.mp4"

  var playerViewController: AVPlayerViewController!

  override func viewDidLoad() {
    super.viewDidLoad()
    self.view.backgroundColor = UIColor.black
    setUpContentPlayer()
  }

  func setUpContentPlayer() {
    // Load AVPlayer with path to your content.
    let contentURL = URL(string: ViewController.ContentURLString)
    let player = AVPlayer(url: contentURL)
    playerViewController = AVPlayerViewController()
    playerViewController.player = player

    showContentPlayer()
  }

  func showContentPlayer() {
    self.addChild(playerViewController)
    playerViewController.view.frame = self.view.bounds
    self.view.insertSubview(playerViewController.view, at: 0)
    playerViewController.didMove(toParent:self)
  }

  func hideContentPlayer() {
    // The whole controller needs to be detached so that it doesn't capture
    // events from the remote.
    playerViewController.willMove(toParent:nil)
    playerViewController.view.removeFromSuperview()
    playerViewController.removeFromParent()
  }
}
      

4. 匯入 IMA SDK

接下來,使用現有的匯入陳述式加入 IMA 架構 匯入。

ViewController.m

Objective-C

#import "ViewController.h"

#import <AVKit/AVKit.h>
#import <GoogleInteractiveMediaAds/GoogleInteractiveMediaAds.h>
NSString *const kContentURLString =
    @"https://storage.googleapis.com/interactive-media-ads/media/stock.mp4";
      

Swift

import AVFoundation
import GoogleInteractiveMediaAds
import UIKit

class ViewController: UIViewController {
  static let ContentURLString = "https://storage.googleapis.com/interactive-media-ads/media/stock.mp4"
      

5. 實作內容播放頭追蹤程式和串流結束觀察器

如要播放片中廣告,IMA SDK 必須追蹤目前的位置 三分之一的畫面方法是建立可實作 IMAContentPlayhead。如以下範例所示,如果您使用 AVPlayer SDK 提供的 IMAAVPlayerContentPlayhead 類別可以為您執行此操作。 如果您沒有使用 AVPlayer,就必須在IMAContentPlayhead 和您自己建立的課程

您也需要讓 SDK 知道內容播放完畢, 顯示片尾廣告。方法是呼叫 contentComplete IMAAdsLoader,使用 AVPlayerItemDidPlayToEndTimeNotification

ViewController.m

Objective-C

...

@interface ViewController ()
@property(nonatomic) IMAAVPlayerContentPlayhead *contentPlayhead;
@property(nonatomic) AVPlayerViewController *contentPlayerViewController;
@end

...

- (void)setupContentPlayer {
  // Create a content video player.
  NSURL *contentURL = [NSURL URLWithString:kContentURLString];
  AVPlayer *player = [AVPlayer playerWithURL:contentURL];
  self.contentPlayerViewController = [[AVPlayerViewController alloc] init];
  self.contentPlayerViewController.player = player;
  self.contentPlayerViewController.view.frame = self.view.bounds;
  self.contentPlayhead =
      [[IMAAVPlayerContentPlayhead alloc] initWithAVPlayer:self.contentPlayerViewController.player];

  // Track end of content.
  AVPlayerItem *contentPlayerItem = self.contentPlayerViewController.player.currentItem;
  [NSNotificationCenter.defaultCenter addObserver:self
                                         selector:@selector(contentDidFinishPlaying:)
                                             name:AVPlayerItemDidPlayToEndTimeNotification
                                           object:contentPlayerItem];

  // Attach content video player to view hierarchy.
  [self showContentPlayer];
}

...

- (void)contentDidFinishPlaying:(NSNotification *)notification {}

- (void)dealloc {
  [NSNotificationCenter.defaultCenter removeObserver:self];
}

@end
      

Swift

...

class ViewController: UIViewController {
  static let ContentURLString = "https://storage.googleapis.com/interactive-media-ads/media/stock.mp4"

  var contentPlayhead: IMAAVPlayerContentPlayhead?
  var playerViewController: AVPlayerViewController!

  deinit {
    NotificationCenter.default.removeObserver(self)
  }

...

  func setUpContentPlayer() {
    // Load AVPlayer with path to your content.
    let contentURL! = URL(string: ViewController.ContentURLString)
    let player = AVPlayer(url: contentURL)
    playerViewController = AVPlayerViewController()
    playerViewController.player = player

    // Set up your content playhead and contentComplete callback.
    contentPlayhead = IMAAVPlayerContentPlayhead(avPlayer: player)
    NotificationCenter.default.addObserver(
      self,
      selector: #selector(ViewController.contentDidFinishPlaying(_:)),
      name: NSNotification.Name.AVPlayerItemDidPlayToEndTime,
      object: player.currentItem)

    showContentPlayer()
  }

...

  @objc func contentDidFinishPlaying(_ notification: Notification) {
    adsLoader.contentComplete()
  }
}
      

6. 初始化廣告載入器並發出廣告請求

您必須建立 IMAAdsLoader 例項,才能要求一組廣告。 這個載入器可用來處理與IMAAdsRequest 指定的廣告代碼網址。

最佳做法是,在整個 IMAAdsLoader 中只維護一個 執行個體 生命週期的任何階段如要提出更多廣告請求,請建立新的 IMAAdsRequest 物件,但重複使用相同的 IMAAdsLoader。如要 請參閱 IMA SDK 常見問題

ViewController.m

Objective-C

...

NSString *const kContentURLString =
    @"https://storage.googleapis.com/interactive-media-ads/media/stock.mp4";
NSString *const kAdTagURLString = @"https://pubads.g.doubleclick.net/gampad/ads?"
    @"iu=/21775744923/external/vmap_ad_samples&sz=640x480&"
    @"cust_params=sample_ar%3Dpremidpostlongpod&"
    @"ciu_szs=300x250&gdfp_req=1&ad_rule=1&output=vmap&unviewed_position_start=1&"
    @"env=vp&impl=s&cmsid=496&vid=short_onecue&correlator=";

@interface ViewController ()
@property(nonatomic) IMAAdsLoader *adsLoader;
@property(nonatomic) IMAAVPlayerContentPlayhead *contentPlayhead;
@property(nonatomic) AVPlayerViewController *contentPlayerViewController;
@end

@implementation ViewController

- (void)viewDidLoad {
  [super viewDidLoad];
  self.view.backgroundColor = UIColor.blackColor;
  [self setupContentPlayer];
  [self setupAdsLoader];
}

- (void)viewDidAppear:(BOOL)animated {
  [super viewDidAppear:animated];
  [self requestAds];
}

- (void)setupAdsLoader {
  self.adsLoader = [[IMAAdsLoader alloc] init];
}

- (void)requestAds {
  // Pass the main view as the container for ad display.
  IMAAdDisplayContainer *adDisplayContainer =
      [[IMAAdDisplayContainer alloc] initWithAdContainer:self.view];
  IMAAdsRequest *request = [[IMAAdsRequest alloc] initWithAdTagUrl:kAdTagURLString
                                                adDisplayContainer:adDisplayContainer
                                                   contentPlayhead:self.contentPlayhead
                                                       userContext:nil];
  [self.adsLoader requestAdsWithRequest:request];
}

...

- (void)contentDidFinishPlaying:(NSNotification *)notification {
  // Notify the SDK that the postrolls should be played.
  [self.adsLoader contentComplete];
}

...

@end
      

Swift

...

class ViewController: UIViewController {
  static let ContentURLString = "https://storage.googleapis.com/interactive-media-ads/media/stock.mp4"
  static let AdTagURLString = "https://pubads.g.doubleclick.net/gampad/ads?iu=/21775744923/external/single_ad_samples&sz=640x480&cust_params=sample_ct%3Dlinear&ciu_szs=300x250%2C728x90&gdfp_req=1&output=vast&unviewed_position_start=1&env=vp&impl=s&correlator="

  var adsLoader: IMAAdsLoader!
  var contentPlayhead: IMAAVPlayerContentPlayhead?
  var playerViewController: AVPlayerViewController!

...

  override func viewDidLoad() {
    super.viewDidLoad()
    self.view.backgroundColor = UIColor.black
    setUpContentPlayer()
    setUpAdsLoader()
  }

  override func viewDidAppear(_ animated: Bool) {
    super.viewDidAppear(animated)
    requestAds()
  }

...

  func setUpAdsLoader() {
    adsLoader = IMAAdsLoader(settings: nil)
  }

  func requestAds() {
    // Create ad display container for ad rendering.
    let adDisplayContainer = IMAAdDisplayContainer(adContainer: self.view)
    // Create an ad request with our ad tag, display container, and optional user context.
    let request = IMAAdsRequest(
        adTagUrl: ViewController.AdTagURLString,
        adDisplayContainer: adDisplayContainer,
        contentPlayhead: contentPlayhead,
        userContext: nil)

    adsLoader.requestAds(with: request)
  }

  @objc func contentDidFinishPlaying(_ notification: Notification) {
    adsLoader.contentComplete()
  }
}
      

7. 設定廣告載入器委派

當載入事件成功時,IMAAdsLoader 會呼叫 adsLoadedWithData 方法並向其傳遞 IMAAdsManager 的例項。個人中心 然後初始化廣告管理系統,並依定義載入個別廣告 。

另外,請務必處理載入期間可能發生的所有錯誤 上傳資料集之後,您可以運用 AutoML 自動完成部分資料準備工作如果未載入廣告,請確認媒體播放作業持續, 以免干擾使用者體驗。

ViewController.m

Objective-C

...

@interface ViewController () <IMAAdsLoaderDelegate>
@property(nonatomic) IMAAdsLoader *adsLoader;
@property(nonatomic) IMAAdsManager *adsManager;
@property(nonatomic) IMAAVPlayerContentPlayhead *contentPlayhead;
@property(nonatomic) AVPlayerViewController *contentPlayerViewController;
@end

@implementation ViewController

...

- (void)setupAdsLoader {
  self.adsLoader = [[IMAAdsLoader alloc] init];
  self.adsLoader.delegate = self;
}

...

#pragma mark - IMAAdsLoaderDelegate

- (void)adsLoader:(IMAAdsLoader *)loader adsLoadedWithData:(IMAAdsLoadedData *)adsLoadedData {
  // Initialize and listen to the ads manager loaded for this request.
  self.adsManager = adsLoadedData.adsManager;
  [self.adsManager initializeWithAdsRenderingSettings:nil];
}

- (void)adsLoader:(IMAAdsLoader *)loader failedWithErrorData:(IMAAdLoadingErrorData *)adErrorData {
  // Fall back to playing content.
  NSLog(@"Error loading ads: %@", adErrorData.adError.message);
  [self.contentPlayerViewController.player play];
}

@end
      

Swift

...

class ViewController: UIViewController, IMAAdsLoaderDelegate {

...

  var adsLoader: IMAAdsLoader!
  var adsManager: IMAAdsManager!
  var contentPlayhead: IMAAVPlayerContentPlayhead?
  var playerViewController: AVPlayerViewController!

...

  func setUpAdsLoader() {
    adsLoader = IMAAdsLoader(settings: nil)
    adsLoader.delegate = self
  }

...

  // MARK: - IMAAdsLoaderDelegate

  func adsLoader(_ loader: IMAAdsLoader!, adsLoadedWith adsLoadedData: IMAAdsLoadedData!) {
    adsManager = adsLoadedData.adsManager
    adsManager.initialize(with: nil)
  }

  func adsLoader(_ loader: IMAAdsLoader!, failedWith adErrorData: IMAAdLoadingErrorData!) {
    print("Error loading ads: " + adErrorData.adError.message)
    showContentPlayer()
    playerViewController.player?.play()
  }
}
      

8. 設定廣告管理工具委派代表

最後,如要管理事件和狀態變更,必須指派 基礎架構IMAAdManagerDelegate 具有處理廣告事件和錯誤的方法。 以及觸發播放和暫停影片內容的方法

開始播放

didReceiveAdEvent 方法可處理許多事件, 不過在這個基本範例中,只要監聽 LOADED 事件來告知廣告 管理員開始播放內容和廣告。

ViewController.m

Objective-C

@interface ViewController () <IMAAdsLoaderDelegate, IMAAdsManagerDelegate>

...

- (void)adsLoader:(IMAAdsLoader *)loader adsLoadedWithData:(IMAAdsLoadedData *)adsLoadedData {
  // Initialize and listen to the ads manager loaded for this request.
  self.adsManager = adsLoadedData.adsManager;
  self.adsManager.delegate = self;
  [self.adsManager initializeWithAdsRenderingSettings:nil];
}

...

#pragma mark - IMAAdsManagerDelegate

- (void)adsManager:(IMAAdsManager *)adsManager didReceiveAdEvent:(IMAAdEvent *)event {
  // Play each ad once it has loaded.
  if (event.type == kIMAAdEvent_LOADED) {
    [adsManager start];
  }
}

...
      

Swift

...

class ViewController: UIViewController, IMAAdsLoaderDelegate, IMAAdsManagerDelegate {

...

  func adsLoader(_ loader: IMAAdsLoader!, adsLoadedWith adsLoadedData: IMAAdsLoadedData!) {
    // Grab the instance of the IMAAdsManager and set yourself as the delegate.
    adsManager = adsLoadedData.adsManager
    adsManager.delegate = self
    adsManager.initialize(with: nil)
  }

...

  // MARK: - IMAAdsManagerDelegate

  func adsManager(_ adsManager: IMAAdsManager!, didReceive event: IMAAdEvent!) {
    // Play each ad once it has been loaded
    if event.type == IMAAdEventType.LOADED {
      adsManager.start()
    }
  }

...
      

處理錯誤

您也可以在廣告錯誤中加入處理常式,如果發生錯誤 (例如先前的 步驟可繼續播放內容

ViewController.m

Objective-C

...

- (void)adsManager:(IMAAdsManager *)adsManager didReceiveAdError:(IMAAdError *)error {
  // Fall back to playing content.
  NSLog(@"AdsManager error: %@", error.message);
  [self showContentPlayer];
  [self.contentPlayerViewController.player play];
}
@end
      

Swift

...

  func adsManager(_ adsManager: IMAAdsManager!, didReceive error: IMAAdError!) {
    // Fall back to playing content
    print("AdsManager error: " + error.message)
    showContentPlayer()
    playerViewController.player?.play()
  }
      

觸發播放和暫停事件

您需要實作的最後兩個委派方法會用於觸發播放程序,以及 暫停事件 (在 IMA SDK 請求時)。 收到請求時觸發暫停和播放,可避免使用者缺漏部分資訊 會隨著廣告顯示

ViewController.m

Objective-C

...

- (void)adsManagerDidRequestContentPause:(IMAAdsManager *)adsManager {
  // Pause the content for the SDK to play ads.
  [self.contentPlayerViewController.player pause];
  [self hideContentPlayer];
}

- (void)adsManagerDidRequestContentResume:(IMAAdsManager *)adsManager {
  // Resume the content since the SDK is done playing ads (at least for now).
  [self showContentPlayer];
  [self.contentPlayerViewController.player play];
}

@end
      

Swift

...

  func adsManagerDidRequestContentPause(_ adsManager: IMAAdsManager!) {
    // Pause the content for the SDK to play ads.
    playerViewController.player?.pause()
    hideContentPlayer()
  }

  func adsManagerDidRequestContentResume(_ adsManager: IMAAdsManager!) {
    // Resume the content since the SDK is done playing ads (at least for now).
    showContentPlayer()
    playerViewController.player?.play()
  }
}
      

大功告成!現在,您透過 IMA SDK 請求及顯示廣告。學習 如要進一步瞭解 SDK 的其他功能,請參閱其他指南 GitHub 上的範例

後續步驟

如要在 iOS 平台上盡量提高廣告收益,請要求應用程式資訊公開和追蹤權限以使用廣告識別碼
