swift - 如何从 RTF 文件 Swift 3 共享文本

Question

我什至不确定这是否可行，但无论如何:

我的应用程序中有 RTF 文件，用于填充 TextView 。我希望我的用户能够共享这些文件中的文本，而不是文件本身。

这是我目前用来共享文件的代码:

@IBAction func shareRecipeTxtBtn(_ sender: Any) {

    let grabIngredientTxt = Bundle.main.url(forResource: "bananaPancakes_ing", withExtension: "rtf")
    let grabDirectionTxt = Bundle.main.url(forResource: "bananaPancakes_dir", withExtension: "rtf")

    let txtToShare = [grabIngredientTxt, grabDirectionTxt]

    let activityViewController = UIActivityViewController(activityItems: txtToShare, applicationActivities: nil)
    activityViewController.popoverPresentationController?.sourceView = self.view 

    activityViewController.excludedActivityTypes = [UIActivityType.postToFacebook, UIActivityType.postToTwitter]

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

所附的屏幕截图是上面代码的结果，但并不理想。

Answer 1

为什么不从 TextView 中获取正在显示的文本

let txtToShare = [textView1.text, textView2.text]

或

let txtToShare = ["\(textView1.text)\n\(textView2.text)]
