Ios 这个popover类的名称是什么？

我找不到此“

popover

”的类的名称。苹果在他们的应用程序中经常使用它

我搜索了

popover

，

NSAlert

，自定义隐藏/可见视图，以及更多

它叫什么

这是

UIAlertController

。在ios7之前，它被称为

UIActionSheet

UIAlertController

对象向用户显示警报消息。此类替换用于显示警报的UIActionSheet和UIAlertView类

    @IBAction func showActionSheetTapped(sender: AnyObject) {
  //Create the AlertController
  let actionSheetController: UIAlertController = UIAlertController(title: "Action Sheet", message: "Swiftly Now! Choose an option!", preferredStyle: .ActionSheet)

  //Create and add the Cancel action
  let cancelAction: UIAlertAction = UIAlertAction(title: "Cancel", style: .Cancel) { action -> Void in
    //Just dismiss the action sheet
  }
  actionSheetController.addAction(cancelAction)
    //Create and add first option action
  let takePictureAction: UIAlertAction = UIAlertAction(title: "Take Picture", style: .Default) { action -> Void in
    //Code for launching the camera goes here
    }
  actionSheetController.addAction(takePictureAction)
  //Create and add a second option action
  let choosePictureAction: UIAlertAction = UIAlertAction(title: "Choose From Camera Roll", style: .Default) { action -> Void in
    //Code for picking from camera roll goes here
    }
  actionSheetController.addAction(choosePictureAction)

  //Present the AlertController
  self.presentViewController(actionSheetController, animated: true, completion: nil)
}

它可能会对您有所帮助。

看起来像是UIAlertControllerInDect，在Xcode 6 UIActionShit中的样式ActionSheet，现在Xcode 7是UIAlertController，还添加了“UIActionShit”
