swift - 在 Swift 3 中使用 "WKAudiovisualMediaTypeNone"时出错

Question

尝试为 WKWebview 添加 WKAudiovisualMediaTypeNone 到 mediaTypesRequiringUserActionForPlayback。但我无法让它工作。

错误

"Use of unresolved identifier 'WKaudiovisualMediaTypeNone'"

在此上下文中

required init?(coder aDecoder: NSCoder) {
    let webConfiguration = WKWebViewConfiguration()
    webConfiguration.allowsInlineMediaPlayback = true
    webConfiguration.mediaTypesRequiringUserActionForPlayback = WKAudiovisualMediaTypeNone; // Error getting here
    self.webView = WKWebView(frame: CGRectZero, configuration: webConfiguration) 
    super.init(coder: aDecoder)
}

请帮忙

.None 没有选项。如果你不想传递任何东西，你可以使用下面的代码:

let webConfiguration = WKWebViewConfiguration()
webConfiguration.allowsInlineMediaPlayback = true
if #available(iOS 10.0, *) {
    webConfiguration.mediaTypesRequiringUserActionForPlayback = []
} else {
    // Fallback on earlier versions
    webConfiguration.mediaPlaybackRequiresUserAction = false
}
self.webView = WKWebView(frame: CGRectZero, configuration: webConfiguration)
