Swift UIAlertController 获取文本字段文本 [英] Swift UIAlertController Getting Text Field Text

问题描述

当按下输入按钮时，我需要从警报视图中的文本字段中获取文本.

I need to get the text from the text fields in my alert view when the Input button is pressed.

func inputMsg() {

    var points = ""
    var outOf = ""

    var alertController = UIAlertController(title: "Input View", message: "Please Input Your Grade", preferredStyle: UIAlertControllerStyle.Alert)

    let actionCancle = UIAlertAction(title: "Cancle", style: UIAlertActionStyle.Cancel) { ACTION in

        println("Cacle")
    }
    let actionInput = UIAlertAction(title: "Input", style: UIAlertActionStyle.Default) { ACTION in

        println("Input")
        println(points)
        println(outOf)
    }

    alertController.addAction(actionCancle)
    alertController.addAction(actionInput)
    alertController.addTextFieldWithConfigurationHandler({(txtField: UITextField!) in
        txtField.placeholder = "I got"
        txtField.keyboardType = UIKeyboardType.NumberPad
        points = txtField.text
        })



    alertController.addTextFieldWithConfigurationHandler({(txtField: UITextField!) in
        txtField.placeholder = "Out Of"
        txtField.keyboardType = UIKeyboardType.NumberPad
        outOf = txtField.text
    })
    presentViewController(alertController, animated: true, completion: nil)
}

推荐答案

UIAlertController 有一个 textFields 属性.那是它的文本字段.您的任何处理程序都可以检查它，从而可以从任何文本字段中获取文本.

The UIAlertController has a textFields property. That's its text fields. Any of your handlers can examine it and thus can get the text from any of the text fields.
