【问题描述】：

如何在swift中实现WKWebView的UIActivityViewController？

我有以下 UIActivityViewController 实现，不幸的是，共享操作的 ActivityView 没有显示。

代码更新：

class ViewController: UIViewController, WKNavigationDelegate {

var webView: WKWebView!

override func viewDidLoad() {
    super.viewDidLoad()

    self.loadView();
}

override func loadView() {
    webView = WKWebView()
    webView.navigationDelegate = self
    view = webView

    let url = URL(string: "https://www.google.com")!
    webView.load(URLRequest(url: url))
    webView.allowsBackForwardNavigationGestures = true
    webView.allowsLinkPreview = true

    let items = [url]
    let activityViewController = UIActivityViewController(activityItems: items , applicationActivities: nil)
    activityViewController.popoverPresentationController?.sourceView = self.view
    self.present(activityViewController, animated: true, completion: nil)
}

...

}

请问，你的位置在哪里？
@IMHiteshSurani 我在我的问题中添加了代码更新
您只需要在 viewDidAppper 中添加共享代码，而不是 viewDidLoad 方法。我稍后会添加详细代码

【解决方案1】：

你不能presentviewDidLoad中的控制器

代码：

var webView: WKWebView!

override func viewDidLoad() {
      super.viewDidLoad()
      loadCMSData()
  }

fileprivate func loadCMSData(){
    webView = WKWebView()
    webView.navigationDelegate = self
    view = webView

    let url = URL(string: "https://www.google.com")!
    webView.load(URLRequest(url: url))
    webView.allowsBackForwardNavigationGestures = true
    webView.allowsLinkPreview = true
}


override func viewDidAppear(_ animated: Bool) {
    let url = URL(string: "https://www.google.com")!
    let items = [url]
    let activityViewController = UIActivityViewController(activityItems: items , applicationActivities: nil)
    activityViewController.popoverPresentationController?.sourceView = self.view
    self.present(activityViewController, animated: true, completion: nil)
}
