共享按钮未在iMessage上共享

如何解决共享按钮未在iMessage上共享

我正在尝试实现一个共享按钮，该按钮允许通过短信共享表格视图中的文章，但是由于某些原因，当我在模拟器中运行该按钮时，它不会复制链接，也不会在iPhone 8上显示或8加。我该如何解决？

@IBAction func shareButton(_ sender: UIButton) {
        
        let buttonPosition = sender.convert(CGPoint.zero,to: self.table_view)
        if let indexPath = self.table_view.indexPathForRow(at:buttonPosition) {
            let newRelease = articles?[indexPath.row].urlWebsite
            let activityVC = UIActivityViewController(activityItems:[newRelease ?? 0],applicationActivities: nil)
            activityVC.popoverPresentationController?.sourceView = self.view
            self.present(activityVC,animated: true,completion: nil)

        }
