Menyiapkan dengan DAI layanan penuh

Pilih platform: HTML5 Android iOS tvOS Cast Roku

Panduan ini membahas cara mengintegrasikan IMA DAI SDK ke dalam aplikasi pemutar video. Jika Anda ingin melihat atau mengikuti contoh integrasi yang sudah selesai, download BasicExample dari GitHub.

Ringkasan IMA DAI

Penerapan IMA DAI melibatkan empat komponen SDK utama, seperti yang ditunjukkan dalam panduan ini:

  • IMAAdDisplayContainer – Objek penampung yang berada di atas elemen pemutaran video dan menampung elemen UI iklan.
  • IMAAdsLoader – Objek yang meminta streaming dan menangani peristiwa yang dipicu oleh objek respons permintaan streaming. Anda hanya boleh membuat satu instance pemuat iklan, yang dapat digunakan kembali selama masa aktif aplikasi.
  • IMAStreamRequest – IMAVODStreamRequest atau IMALiveStreamRequest. Objek yang menentukan permintaan streaming. Permintaan streaming dapat berupa video on demand atau live stream. Permintaan live stream menentukan kunci aset, sedangkan permintaan VOD menentukan ID CMS dan ID video. Kedua jenis permintaan dapat secara opsional menyertakan kunci API yang diperlukan untuk mengakses streaming yang ditentukan, dan kode jaringan Google Ad Manager untuk IMA SDK guna menangani ID iklan seperti yang ditentukan dalam setelan Google Ad Manager.
  • IMAStreamManager – Objek yang menangani streaming penyisipan iklan dinamis dan interaksi dengan backend DAI. Pengelola aliran juga menangani ping pelacakan serta meneruskan peristiwa aliran dan iklan ke penayang.

Prasyarat

Sebelum memulai, Anda memerlukan hal berikut:

Anda juga memerlukan parameter untuk meminta streaming dari IMA SDK. Untuk contoh parameter permintaan, lihat Contoh Streaming.

Parameter livestream
Kunci aset Kunci aset yang mengidentifikasi livestream Anda di Google Ad Manager.
Contoh: c-rArva4ShKVIAkNfy6HUQ
Parameter streaming VOD
ID sumber konten ID sumber konten dari Google Ad Manager.
Contoh: 2548831
ID Video ID video dari Google Ad Manager.
Contoh: tears-of-steel
Parameter umum (VOD dan livestream)
Kode jaringan Kode jaringan Google Ad Manager Anda.
Contoh: 21775744923

Membuat project Xcode baru

Di Xcode, buat project iOS baru menggunakan Objective-C bernama "BasicExample".

Menambahkan IMA DAI SDK ke project Xcode

Untuk menginstal IMA SDK, pilih metode yang diinginkan.

Direkomendasikan: Instal SDK menggunakan Swift Package Manager

Interactive Media Ads SDK mendukung Swift Package Manager mulai versi 3.18.4. Ikuti langkah-langkah berikut untuk mengimpor paket Swift.

  1. Di Xcode, instal Paket Swift IMA DAI SDK: buka File > Add Packages.

  2. Pada perintah yang muncul, telusuri repositori GitHub Paket Swift IMA DAI SDK:

    https://github.com/googleads/swift-package-manager-google-interactive-media-ads-ios

  3. Pilih versi Paket Swift IMA DAI SDK yang ingin Anda gunakan. Untuk project baru, gunakan Up to Next Major Version.

Setelah selesai, Xcode akan me-resolve dependensi paket Anda dan mendownloadnya di latar belakang. Untuk mengetahui detail selengkapnya tentang cara menambahkan dependensi paket, lihat artikel Apple.

Mendownload dan menginstal SDK secara manual

Jika tidak ingin menggunakan Swift Package Manager, download dan tambahkan IMA SDK secara manual ke project Anda.

Membuat pemutar video

Terapkan pemutar video di pengontrol tampilan utama; gabungkan pemutar AV dalam tampilan UI. IMA SDK menggunakan tampilan UI untuk menampilkan elemen UI iklan.

Objective-C

#import "ViewController.h"

#import <AVKit/AVKit.h>

/// Content URL.
static NSString *const kBackupContentUrl =
    @"http://devimages.apple.com/iphone/samples/bipbop/bipbopall.m3u8";

@interface ViewController ()
/// Play button.
@property(nonatomic, weak) IBOutlet UIButton *playButton;

@property(nonatomic, weak) IBOutlet UIView *videoView;
/// Video player.
@property(nonatomic, strong) AVPlayer *videoPlayer;
@end

@implementation ViewController

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

  // Load AVPlayer with the path to your content.
  NSURL *contentURL = [NSURL URLWithString:kBackupContentUrl];
  self.videoPlayer = [AVPlayer playerWithURL:contentURL];

  // Create a player layer for the player.
  AVPlayerLayer *playerLayer = [AVPlayerLayer playerLayerWithPlayer:self.videoPlayer];

  // Size, position, and display the AVPlayer.
  playerLayer.frame = self.videoView.layer.bounds;
  [self.videoView.layer addSublayer:playerLayer];
}

- (IBAction)onPlayButtonTouch:(id)sender {
  [self.videoPlayer play];
  self.playButton.hidden = YES;
}

@end

class ViewController: UIViewController {

  /// Content URL.
  static let backupStreamURLString =
    "http://devimages.apple.com/iphone/samples/bipbop/bipbopall.m3u8"

  /// Play button.
  @IBOutlet private weak var playButton: UIButton!

  @IBOutlet private weak var videoView: UIView!
  /// Video player.
  private var videoPlayer: AVPlayer?

  override func viewDidLoad() {
    super.viewDidLoad()

    playButton.layer.zPosition = CGFloat(MAXFLOAT)

    // Load AVPlayer with path to our content.
    // note: this unwrap is safe because the URL is a constant string.
    let contentURL = URL(string: ViewController.backupStreamURLString)!
    videoPlayer = AVPlayer(url: contentURL)

    // Create a player layer for the player.
    let playerLayer = AVPlayerLayer(player: videoPlayer)

    // Size, position, and display the AVPlayer.
    playerLayer.frame = videoView.layer.bounds
    videoView.layer.addSublayer(playerLayer)
  }

  @IBAction func onPlayButtonTouch(_ sender: Any) {
    videoPlayer?.play()
    playButton.isHidden = true
  }
}

Melakukan inisialisasi loader iklan

Impor IMA SDK ke pengontrol tampilan Anda dan terapkan protokol IMAAdsLoaderDelegate dan IMAStreamManagerDelegate untuk menangani peristiwa pemuat iklan dan pengelola streaming.

Tambahkan properti pribadi ini untuk menyimpan komponen IMA SDK utama:

  • IMAAdsLoader
    • Mengelola permintaan streaming selama masa aktif aplikasi Anda.
  • IMAAdDisplayContainer
    • Menangani penyisipan dan pengelolaan elemen antarmuka pengguna iklan.
  • IMAAVPlayerVideoDisplay - Berkomunikasi antara IMA SDK dan pemutar media Anda serta menangani metadata berwaktu.
  • IMAStreamManager - Mengelola pemutaran streaming dan mengaktifkan peristiwa terkait iklan.

Lakukan inisialisasi loader iklan, penampung tampilan iklan, dan tampilan video setelah tampilan dimuat.

Objective-C

@import GoogleInteractiveMediaAds;

// ...

@interface ViewController () <IMAAdsLoaderDelegate, IMAStreamManagerDelegate>
/// The entry point for the IMA DAI SDK to make DAI stream requests.
@property(nonatomic, strong) IMAAdsLoader *adsLoader;
/// The container where the SDK renders each ad's user interface elements and companion slots.
@property(nonatomic, strong) IMAAdDisplayContainer *adDisplayContainer;
/// The reference of your video player for the IMA DAI SDK to monitor playback and handle timed
/// metadata.
@property(nonatomic, strong) IMAAVPlayerVideoDisplay *imaVideoDisplay;
/// References the stream manager from the IMA DAI SDK after successful stream loading.
@property(nonatomic, strong) IMAStreamManager *streamManager;

// ...

@end

@implementation ViewController

- (void)viewDidLoad {
  [super viewDidLoad];

  // ...

  self.adsLoader = [[IMAAdsLoader alloc] initWithSettings:nil];
  self.adsLoader.delegate = self;

  // Create an ad display container for rendering each ad's user interface elements and companion
  // slots.
  self.adDisplayContainer =
      [[IMAAdDisplayContainer alloc] initWithAdContainer:self.videoView
                                          viewController:self
                                          companionSlots:nil];

  // Create an IMAAVPlayerVideoDisplay to give the SDK access to your video player.
  self.imaVideoDisplay = [[IMAAVPlayerVideoDisplay alloc] initWithAVPlayer:self.videoPlayer];
}

Swift

import GoogleInteractiveMediaAds
// ...

class ViewController: UIViewController, IMAAdsLoaderDelegate, IMAStreamManagerDelegate {
  // ...

  /// The entry point for the IMA DAI SDK to make DAI stream requests.
  private var adsLoader: IMAAdsLoader?
  /// The container where the SDK renders each ad's user interface elements and companion slots.
  private var adDisplayContainer: IMAAdDisplayContainer?
  /// The reference of your video player for the IMA DAI SDK to monitor playback and handle timed
  /// metadata.
  private var imaVideoDisplay: IMAAVPlayerVideoDisplay!
  /// References the stream manager from the IMA DAI SDK after successfully loading the DAI stream.
  private var streamManager: IMAStreamManager?

  // ...

  override func viewDidLoad() {
    super.viewDidLoad()

    // ...

    adsLoader = IMAAdsLoader(settings: nil)
    adsLoader?.delegate = self

    // Create an ad display container for rendering ad UI elements and the companion ad.
    adDisplayContainer = IMAAdDisplayContainer(
      adContainer: videoView,
      viewController: self,
      companionSlots: nil)

    // Create an IMAAVPlayerVideoDisplay to give the SDK access to your video player.
    imaVideoDisplay = IMAAVPlayerVideoDisplay(avPlayer: videoPlayer)
  }

Membuat permintaan streaming

Saat pengguna menekan tombol putar, buat permintaan streaming baru. Gunakan class IMALiveStreamRequest untuk Live stream. Untuk streaming VOD, gunakan class IMAVODStreamRequest.

Permintaan streaming memerlukan parameter streaming, serta referensi ke penampung tampilan iklan dan tampilan video Anda.

Objective-C

- (IBAction)onPlayButtonTouch:(id)sender {
  [self requestStream];
  self.playButton.hidden = YES;
}

- (void)requestStream {
  // Create a stream request. Use one of "Live stream request" or "VOD request", depending on your
  // type of stream.
  if (kStreamType == StreamTypeLive) {
    // Live stream request. Replace the asset key with your value.
    IMALiveStreamRequest *request =
        [[IMALiveStreamRequest alloc] initWithAssetKey:kLiveStreamAssetKey
                                           networkCode:kNetworkCode
                                    adDisplayContainer:self.adDisplayContainer
                                          videoDisplay:self.imaVideoDisplay
                                           userContext:nil];
    request.useHLSInterstitials = YES;
    [self.adsLoader requestStreamWithRequest:request];
  } else {
    // VOD request. Replace the content source ID and video ID with your values.
    IMAVODStreamRequest *request =
        [[IMAVODStreamRequest alloc] initWithContentSourceID:kVODContentSourceID
                                                     videoID:kVODVideoID
                                                 networkCode:kNetworkCode
                                          adDisplayContainer:self.adDisplayContainer
                                                videoDisplay:self.imaVideoDisplay
                                                 userContext:nil];
    [self.adsLoader requestStreamWithRequest:request];
  }
}

Swift

@IBAction func onPlayButtonTouch(_ sender: Any) {
  requestStream()
  playButton.isHidden = true
}

func requestStream() {
  // Create a stream request. Use one of "Livestream request" or "VOD request".
  if ViewController.requestType == StreamType.live {
    // Livestream request.
    let request = IMALiveStreamRequest(
      assetKey: ViewController.assetKey,
      networkCode: ViewController.networkCode,
      adDisplayContainer: adDisplayContainer!,
      videoDisplay: imaVideoDisplay,
      userContext: nil)
    request.useHLSInterstitials = true
    adsLoader?.requestStream(with: request)
  } else {
    // VOD stream request.
    let request = IMAVODStreamRequest(
      contentSourceID: ViewController.contentSourceID,
      videoID: ViewController.videoID,
      networkCode: ViewController.networkCode,
      adDisplayContainer: adDisplayContainer!,
      videoDisplay: imaVideoDisplay,
      userContext: nil)
    adsLoader?.requestStream(with: request)
  }
}

Memproses peristiwa pemuatan streaming

Class IMAAdsLoader memanggil metode IMAAdsLoaderDelegate saat inisialisasi berhasil atau gagal pada permintaan streaming.

Dalam metode delegasi adsLoadedWithData, tetapkan IMAStreamManagerDelegate Anda. Melakukan inisialisasi pengelola streaming. Saat inisialisasi, pengelola streaming memulai pemutaran.

Dalam metode delegasi failedWithErrorData, catat error ke dalam log. Atau, putar streaming cadangan. Lihat praktik terbaik DAI.

Objective-C

- (void)adsLoader:(IMAAdsLoader *)loader adsLoadedWithData:(IMAAdsLoadedData *)adsLoadedData {
  NSLog(@"Stream created with: %@.", adsLoadedData.streamManager.streamId);
  self.streamManager = adsLoadedData.streamManager;
  self.streamManager.delegate = self;
  [self.streamManager initializeWithAdsRenderingSettings:nil];
}

- (void)adsLoader:(IMAAdsLoader *)loader failedWithErrorData:(IMAAdLoadingErrorData *)adErrorData {
  // Log the error and play the content.
  NSLog(@"AdsLoader error, code:%ld, message: %@", adErrorData.adError.code,
        adErrorData.adError.message);
  [self.videoPlayer play];
}

Swift

func adsLoader(_ loader: IMAAdsLoader, adsLoadedWith adsLoadedData: IMAAdsLoadedData) {
  print("DAI stream loaded. Stream session ID: \(adsLoadedData.streamManager!.streamId!)")
  streamManager = adsLoadedData.streamManager!
  streamManager!.delegate = self
  streamManager!.initialize(with: nil)
}

func adsLoader(_ loader: IMAAdsLoader, failedWith adErrorData: IMAAdLoadingErrorData) {
  print("Error loading DAI stream. Error message: \(adErrorData.adError.message!)")
  // Play the backup stream.
  videoPlayer.play()
}

Memproses peristiwa iklan

IMAStreamManager memanggil metode IMAStreamManagerDelegate untuk meneruskan peristiwa dan error streaming ke aplikasi Anda.

Untuk contoh ini, catat peristiwa iklan utama ke konsol:

Objective-C

- (void)streamManager:(IMAStreamManager *)streamManager didReceiveAdEvent:(IMAAdEvent *)event {
  NSLog(@"Ad event (%@).", event.typeString);
  switch (event.type) {
    case kIMAAdEvent_STARTED: {
      // Log extended data.
      NSString *extendedAdPodInfo = [[NSString alloc]
          initWithFormat:@"Showing ad %ld/%ld, bumper: %@, title: %@, description: %@, contentType:"
                         @"%@, pod index: %ld, time offset: %lf, max duration: %lf.",
                         (long)event.ad.adPodInfo.adPosition, (long)event.ad.adPodInfo.totalAds,
                         event.ad.adPodInfo.isBumper ? @"YES" : @"NO", event.ad.adTitle,
                         event.ad.adDescription, event.ad.contentType,
                         (long)event.ad.adPodInfo.podIndex, event.ad.adPodInfo.timeOffset,
                         event.ad.adPodInfo.maxDuration];

      NSLog(@"%@", extendedAdPodInfo);
      break;
    }
    case kIMAAdEvent_AD_BREAK_STARTED: {
      NSLog(@"Ad break started");
      break;
    }
    case kIMAAdEvent_AD_BREAK_ENDED: {
      NSLog(@"Ad break ended");
      break;
    }
    case kIMAAdEvent_AD_PERIOD_STARTED: {
      NSLog(@"Ad period started");
      break;
    }
    case kIMAAdEvent_AD_PERIOD_ENDED: {
      NSLog(@"Ad period ended");
      break;
    }
    default:
      break;
  }
}

- (void)streamManager:(IMAStreamManager *)streamManager didReceiveAdError:(IMAAdError *)error {
  NSLog(@"StreamManager error with type: %ld\ncode: %ld\nmessage: %@", error.type, error.code,
        error.message);
  [self.videoPlayer play];
}

Swift

func streamManager(_ streamManager: IMAStreamManager, didReceive event: IMAAdEvent) {
  print("Ad event \(event.typeString).")
  switch event.type {
  case IMAAdEventType.STARTED:
    // Log extended data.
    if let ad = event.ad {
      let extendedAdPodInfo = String(
        format: "Showing ad %zd/%zd, bumper: %@, title: %@, "
          + "description: %@, contentType:%@, pod index: %zd, "
          + "time offset: %lf, max duration: %lf.",
        ad.adPodInfo.adPosition,
        ad.adPodInfo.totalAds,
        ad.adPodInfo.isBumper ? "YES" : "NO",
        ad.adTitle,
        ad.adDescription,
        ad.contentType,
        ad.adPodInfo.podIndex,
        ad.adPodInfo.timeOffset,
        ad.adPodInfo.maxDuration)

      print("\(extendedAdPodInfo)")
    }
    break
  case IMAAdEventType.AD_BREAK_STARTED:
    print("Ad break started.")
    break
  case IMAAdEventType.AD_BREAK_ENDED:
    print("Ad break ended.")
    break
  case IMAAdEventType.AD_PERIOD_STARTED:
    print("Ad period started.")
    break
  case IMAAdEventType.AD_PERIOD_ENDED:
    print("Ad period ended.")
    break
  default:
    break
  }
}

func streamManager(_ streamManager: IMAStreamManager, didReceive error: IMAAdError) {
  print("StreamManager error with type: \(error.type)")
  print("code: \(error.code)")
  print("message: \(error.message ?? "Unknown Error")")
}

Jalankan aplikasi Anda. Jika berhasil, minta dan putar streaming DAI Google dengan IMA SDK. Untuk mempelajari fitur SDK lanjutan lainnya, lihat panduan lain yang tercantum di sidebar sebelah kiri atau contoh di GitHub.
