IMA SDK 可让您轻松地将多媒体广告集成到您的网站和应用中。IMA SDK 可以 向任意 <ph type="x-smartling-placeholder"></ph> 符合 VAST 标准的广告服务器,并管理应用中的广告播放。借助 IMA 客户端 SDK 您控制内容视频播放,而 SDK 处理广告播放。广告播放 独立的视频播放器,位于应用的内容视频播放器之上。
本指南将演示如何将 IMA SDK 集成到简单的视频播放器中 应用。如果您想查看或了解已完成的示例 集成,请下载 BasicExample GitHub。
IMA 客户端概览
实施 IMA 客户端涉及四个主要 SDK 组件,它们是 演示:
IMAAdDisplayContainer
: 用于呈现广告的容器对象。IMAAdsLoader
: 用于请求广告并处理广告请求响应中事件的对象。您只能 实例化一个广告加载器,该加载器可在应用的整个生命周期内重复使用。IMAAdsRequest
: 用于定义广告请求的对象。广告请求会指定 VAST 广告代码的网址,以及 其他参数(例如广告尺寸)IMAAdsManager
: 一个对象,包含对广告请求的响应、控制广告播放以及监听广告 所有事件。
前提条件
在开始之前,您需要做好以下准备:
- Xcode 13 或更高版本
- CocoaPods(首选)、Swift Package Manager 或 下载了 适用于 iOS 的 IMA SDK
1. 创建新的 Xcode 项目
在 Xcode 中,使用 Objective-C 或 Swift 创建一个新的 iOS 项目。使用 BasicExample 作为项目名称。
2. 将 IMA SDK 添加到 Xcode 项目
使用 CocoaPods 安装 SDK(推荐)
CocoaPods 是适用于 Xcode 项目的依赖项管理器,建议使用 CocoaPods 安装 IMA SDK 的方法。如需详细了解如何安装或使用 CocoaPods,请参阅 CocoaPods 文档。在您 已安装 CocoaPods,请按照以下说明安装 IMA SDK:
在 BasicExample.xcodeproj 文件所在的同一目录中,创建一个文本 名为 Podfile 的文件,并添加以下配置:
source 'https://github.com/CocoaPods/Specs.git' platform :ios, '14' target "BasicExample" do pod 'GoogleAds-IMA-iOS-SDK', '~> 3.23.0' end
从包含 Podfile 的目录中,运行
pod install --repo-update
打开 BasicExample.xcworkspace 文件并确认它包含两个项目: BasicExample 和 Pods(由 CocoaPods 安装的依赖项)。
使用 Swift Package Manager 安装 SDK
互动式媒体广告 SDK 支持 Swift Package Manager 版本。按照 导入 Swift 软件包的步骤。
在 Xcode 中,前往 文件 >添加软件包...。
在显示的提示中,搜索 IMA SDK Swift Package GitHub 代码库:
https://github.com/googleads/swift-package-manager-google-interactive-media-ads-ios
选择您要使用的 IMA SDK Swift 软件包版本。 对于新项目,我们建议使用 Up to Next Major Version。
完成上述操作后,Xcode 会解析您的软件包依赖项 并在后台下载它们如需详细了解如何添加软件包 请参阅 Apple 的文章。
手动下载并安装 SDK
如果您不想使用 Swift Package Manager 或 CocoaPods,可以下载 IMA SDK 并 可以将其手动添加到项目中
3. 创建简单的视频播放器
首先,实施一个基本的视频播放器。最初,该播放器不会使用 IMA SDK 中,但尚未包含任何触发播放的方法。
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. 导入 IMA SDK
接下来,使用 import 语句在现有的 导入。
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. 实现内容进度条指针跟踪器和流结束观察器
要播放中贴片广告,IMA SDK 需要跟踪
视频内容为此,请创建一个实现
IMAContentPlayhead
。如果您使用的是 AVPlayer
(如此例所示),
SDK 提供了 IMAAVPlayerContentPlayhead
类来为您执行此操作。
如果您没有使用 AVPlayer
,则需要在IMAContentPlayhead
是您自己的一个类。
您还需要在内容播放完毕后通知 SDK,以便 SDK
展示后贴片广告。可通过在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. 初始化广告加载器并发出广告请求
为了请求一组广告,您需要创建一个 IMAAdsLoader
实例。
此加载器可用于处理IMAAdsRequest
与
指定的广告代码网址。
最佳做法是,在整个过程中只维护一个 IMAAdsLoader
实例,
应用的整个生命周期要发出更多广告请求,请创建新的
IMAAdsRequest
对象,但重复使用相同的 IMAAdsLoader
。有关
相关信息,请参阅 IMA SDK 常见问题解答。
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. 设置广告加载程序委托
在成功加载事件发生后,IMAAdsLoader
会调用 adsLoadedWithData
方法,并向其传递 IMAAdsManager
的实例。您
然后可以初始化广告管理器,该广告管理器将按照定义加载各个广告,
。
此外,请务必处理在加载过程中可能发生的任何错误 过程。如果广告无法加载,请确保媒体继续播放,而不 以免干扰用户体验。
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. 设置广告管理器委托
最后,为了管理事件和状态变化,广告管理器需要
自己的数据。IMAAdManagerDelegate
提供了用于处理广告事件和错误的方法,
以及触发视频内容的播放和暂停的方法。
正在开始播放
didReceiveAdEvent
方法可用于处理许多事件,
但对于这个基本示例,只需监听 LOADED
事件,让广告
来播放内容和广告。
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() } } ...
处理错误
同时为广告错误添加处理程序。如果出现错误,例如在上一个 继续播放内容。
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() }
触发播放和暂停事件
您需要实现的后两个委托方法用于触发播放, 暂停播放基础视频内容上的事件。 在收到请求时触发暂停和播放操作可防止用户遗漏部分内容 视频内容的播放速度。
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!现在,您将通过 IMA SDK 请求并展示广告。学习内容 其他 SDK 功能,请参阅其他指南或 GitHub 上的示例。
