在WkWebview中启用仅使用WkWebView的not缓存(而不是借助NSURLRequest或NSURLSession)

Question

我知道我可以用NSURLRequest启用缓存

  if reachability.isReachable {
             urlRequestCache=NSURLRequest(URL: url!, cachePolicy: NSURLRequestCachePolicy.UseProtocolCachePolicy, timeoutInterval: 10)
        }
        else {
            urlRequestCache = NSURLRequest(URL: url!, cachePolicy: NSURLRequestCachePolicy.ReturnCacheDataElseLoad, timeoutInterval: 60)
        }
       theWebView.loadRequest(urlRequestCache)

但我无法在WkWebView上找到任何方法来实现这一点。

Swift 4:

var webView = WKWebView()
if let url = URL(string: string) {
        var request = URLRequest(url: url)
        request.cachePolicy = .returnCacheDataElseLoad
        webView.load(request)
}
