           guard let url = myWebsite else {

           }

           let shareItems:Array = [img,url]
           let activityViewController:UIActivityViewController = UIActivityViewController(activityItems: shareItems, applicationActivities: nil)
        activityViewController.excludedActivityTypes = [UIActivity.ActivityType.print, UIActivity.ActivityType.postToWeibo, UIActivity.ActivityType.copyToPasteboard, UIActivity.ActivityType.addToReadingList, UIActivity.ActivityType.postToVimeo]
        self!.present(activityViewController, animated: true, completion: nil)

如果您需要下载图像然后分享，您应该单独进行，没有一种方法可以为您完成。方法如下：

func shareImageFromUrl(_ string: String) {

    guard let myUrl = URL(string: string) else {
        print("Invalid url!")
        return
    }

    URLSession.shared.dataTask(with: myUrl) { (data, _, _) in
        guard let data = data,
            let image = UIImage(data: data) else
        { return }

        let activityViewController:UIActivityViewController = UIActivityViewController(activityItems: [image], applicationActivities: nil)
        activityViewController.excludedActivityTypes = [UIActivity.ActivityType.print, UIActivity.ActivityType.postToWeibo, UIActivity.ActivityType.copyToPasteboard, UIActivity.ActivityType.addToReadingList, UIActivity.ActivityType.postToVimeo]
        DispatchQueue.main.async {
            self.present(activityViewController, animated: true, completion: nil)
        }
    }.resume()
}
