设置 WKWebView

如果您的应用使用 WKWebView 展示 Web 内容，建议您对其进行配置，以便通过广告实现内容的最佳创收效果。

本指南介绍如何提供有关如何配置 WKWebView 对象的信息。

媒体内容

默认的 WKWebView 设置并未针对视频广告进行优化。使用 WKWebViewConfiguration API 配置 WKWebView，以便实现内嵌式播放和自动播放视频。

Swift

import WebKit

class ViewController: UIViewController {

  var webView: WKWebView!

  override func viewDidLoad() {
    super.viewDidLoad()

    // Initialize a WKWebViewConfiguration object.
    let webViewConfiguration = WKWebViewConfiguration()
    // Let HTML videos with a "playsinline" attribute play inline.
    webViewConfiguration.allowsInlineMediaPlayback = true
    // Let HTML videos with an "autoplay" attribute play automatically.
    webViewConfiguration.mediaTypesRequiringUserActionForPlayback = []

    // Initialize the WKWebView with your WKWebViewConfiguration object.
    webView = WKWebView(frame: view.frame, configuration: webViewConfiguration)
    view.addSubview(webView)
  }
}

Objective-C

@import WebKit;

#import "ViewController.h"

@interface ViewController ()

@property(nonatomic, strong) WKWebView *webView;

@end

@implementation ViewController

- (void)viewDidLoad {
  [super viewDidLoad];

  // Initialize a WKWebViewConfiguration object.
  WKWebViewConfiguration *webViewConfiguration = [[WKWebViewConfiguration alloc] init];
  // Let HTML videos with a "playsinline" attribute play inline.
  webViewConfiguration.allowsInlineMediaPlayback = YES;
  // Let HTML videos with an "autoplay" attribute play automatically.
  webViewConfiguration.mediaTypesRequiringUserActionForPlayback = WKAudiovisualMediaTypeNone;

  // Initialize the WKWebView with your WKWebViewConfiguration object.
  self.webView = [[WKWebView alloc] initWithFrame:self.view.frame configuration:webViewConfiguration];
  [self.view addSubview:self.webView];
}

加载 WebView 内容

Cookie 和网页网址对于 WebView 创收至关重要，只有在 load(_:) 与基于网络的网址搭配使用时，才能按预期方式发挥作用。为了优化 WKWebView 性能，我们强烈建议从基于网络的网址加载 Web 内容。

Swift

import WebKit

var webview: WKWebview!

class ViewController: UIViewController {
  override func viewDidLoad() {
    super.viewDidLoad()

    // Initialize a WKWebViewConfiguration object.
    let webViewConfiguration = WKWebViewConfiguration()
    // Let HTML videos with a "playsinline" attribute play inline.
    webViewConfiguration.allowsInlineMediaPlayback = true
    // Let HTML videos with an "autoplay" attribute play automatically.
    webViewConfiguration.mediaTypesRequiringUserActionForPlayback = []

    // Initialize the WKWebView with your WKWebViewConfiguration object.
    webView = WKWebView(frame: view.frame, configuration: webViewConfiguration)
    view.addSubview(webView)

    // Load the URL for optimized web view performance.
    guard let url = URL(string: "https://google.github.io/webview-ads/test/") else { return }
    let request = URLRequest(url: url)
    webView.load(request)
  }
}

Objective-C

@import WebKit;

#import "ViewController.h"

@interface ViewController ()

@property(nonatomic, strong) WKWebView *webView;

@end

@implementation ViewController

- (void)viewDidLoad {
  [super viewDidLoad];

  // Initialize a WKWebViewConfiguration object.
  WKWebViewConfiguration *webViewConfiguration = [[WKWebViewConfiguration alloc] init];
  // Let HTML videos with a "playsinline" attribute play inline.
  webViewConfiguration.allowsInlineMediaPlayback = YES;
  // Let HTML videos with an "autoplay" attribute play automatically.
  webViewConfiguration.mediaTypesRequiringUserActionForPlayback = WKAudiovisualMediaTypeNone;

  // Initialize the WKWebView with your WKWebViewConfiguration object.
  self.webView = [[WKWebView alloc] initWithFrame:self.view.frame configuration:webViewConfiguration];
  [self.view addSubview:self.webview];

  // Load the URL for optimized web view performance.
  NSURL *url = [NSURL URLWithString:@"https://google.github.io/webview-ads/test/"];
  NSURLRequest *request = [NSURLRequest requestWithURL:url];
  [webView loadRequest:request];
}

测试 WebView

在应用开发期间，我们建议您加载此测试网址：

https://google.github.io/webview-ads/test/

以验证这些设置是否对广告产生了预期效果。如果观察到以下情况，则表示测试网址已具备完整集成的成功标准：

网页视图设置

  • 第一方 Cookie 的工作方式
  • JavaScript 已启用

视频广告

  • 视频广告以内嵌方式播放，不会在全屏内置播放器中打开
  • 视频广告会自动播放，无需点击播放按钮
  • 视频广告可重播

测试完成后，将测试网址替换为 WebView 打算加载的网址。
