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,则表示测试网址已成功完成集成:
网页视图设置
- 第一方 Cookie 的运作方式
- 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。
