使用消息时如何设置 UIActivityViewController 的收件人

Question

我正在使用此代码来呈现 UIActivityViewController。

 var a = standard.value(forKey: "first_name") as? String
    let text = a! + " text to share"
    let url : NSURL = NSURL(fileURLWithPath: "https://itunes.apple.com/in/app/")

    let textToShare = [ text as String , url as URL ] as [Any]
    let activityViewController = UIActivityViewController(activityItems: textToShare, applicationActivities: nil)


    activityViewController.popoverPresentationController?.sourceView = self.view // so that iPads won't crash
    activityViewController.completionWithItemsHandler = {
        (s, ok, items, error) in
        if ok == true {
            DispatchQueue.main.async {
               // code after completion
            }

        }
    }
    self.present(activityViewController, animated: true, completion: nil)

但我希望，如果我在 UIActivityViewController 中选择消息选项，那么电话号码应该预先填写我提供的号码。这对于 UIActivityViewController 是否可行？如果是，请向我提供一些有关它的参考或代码
