我正在尝试在iOS 9下使用WKWebView,其中一个页面中有一个嵌入式的Youtube视频。但是视频无法显示。相同的视频在Safari中可以正常播放,因此这似乎不是iOS的问题。我猜测我可能错过了视图中的某个配置选项。示例URL为http://www.w3schools.com/html/tryit.asp?filename=tryhtml_youtubeiframe。
import UIKit
import WebKit
class ViewController: UIViewController, WKNavigationDelegate
{
var webView : WKWebView!
override func viewDidLoad()
{
super.viewDidLoad()
let webviewConfiguration = WKWebViewConfiguration()
webviewConfiguration.allowsInlineMediaPlayback = true
webviewConfiguration.preferences.javaScriptCanOpenWindowsAutomatically = true
webviewConfiguration.allowsAirPlayForMediaPlayback = true
webviewConfiguration.allowsPictureInPictureMediaPlayback = true
webviewConfiguration.requiresUserActionForMediaPlayback = false
webView = WKWebView(frame: self.view.bounds,
configuration: webviewConfiguration)
webView.navigationDelegate = self
self.view = webView
let url = NSURL(string: "http://www.w3schools.com/html/tryit.asp?filename=tryhtml_youtubeiframe")
let req = NSURLRequest(URL: url!)
self.webView!.loadRequest(req)
}
override func didReceiveMemoryWarning()
{
super.didReceiveMemoryWarning()
}
func webView(webView: WKWebView,
didFailNavigation navigation: WKNavigation!,
withError error: NSError)
{
print("didFailNavigation \(error)")
}
func webView(webView: WKWebView,
didFailProvisionalNavigation navigation: WKNavigation!,
withError error: NSError)
{
print("didFailProvisionalNavigation \(error)")
}
}
