Set up WKWebView

If your app utilizes WKWebView to display web content, it's recommended to configure it so that content can be optimally monetized with ads.

This guide shows you how to provide information about how to configure a WKWebView object.

Important: To properly set up and optimize WKWebView, apply all of the following recommendations to each WKWebView instance in your app.

Media Content

Default WKWebView settings are not optimized for video ads. Use the WKWebViewConfiguration APIs to configure your WKWebView for inline playback and automatic video play.

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];
}

Load web view content

Cookies and page URLs are important for web view monetization and only function as expected when load(_:) is used with a network-based URL. For optimized WKWebView performance, we strongly recommend loading web content from a network-based URL.

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];
}

Test the web view

During app development, we recommend that you load this test URL:

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

to verify these settings have the intended effect on ads. The test URL has success criteria for a complete integration if the following are observed:

Web view settings

• First-party cookies work
• JavaScript enabled

Video ad

• The video ad plays inline and does not open in the full screen built-in player
• The video ad plays automatically without clicking the play button
• The video ad is replayable

After testing is complete, substitute the test URL with the URL the web view intends to load.
