ios - 使用 UIButton 文本作为文本输入 - Swift

Question

你好，我有一个如下所示的 profilelbl 变量，它是一个 uibutton。我希望按钮的文本成为我的数据库中的输入(解析)。但我想不通。我尝试了很多东西，但仍然出现错误:

  @IBOutlet weak var profileLbl: UIButton!

  var notification = PFObject(className: "notifications")

        notification["actionReceiverName"] = profilelbl.text /*not working*/

     /*    also tried

   notification["actionReceiverName"] = sender.profilelbl.text

   notification["actionReceiverName"] = profilelbl.title    */

Answer 1

你可以轻松做到这一点

if let button = profilelbl as? UIButton {
    if let title = button.titleForState(.Normal) {
        println(title)
        notification["actionReceiverName"] = title
    }
}
