在Swift中获取UIPickerViewControl的选定值 [英] Getting selected value of a UIPickerViewControl in Swift

问题描述

如何在Swift中获取UIPickerViewControl的选定值？

How can I get the selected value of a UIPickerViewControl in Swift?

我尝试过这样的事情：

labelTest.text = Spinner1.selectedRowInComponent(0).description

但这只返回选定的索引。我需要价值。

But this only returns the selected index. I need the value.

任何知道怎么做的人？

推荐答案

你必须将选择器视图委托设置为self并覆盖此功能

you will have to set the picker view delegate to self and override this function

func pickerView(pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int)
   {
        // use the row to get the selected row from the picker view
        // using the row extract the value from your datasource (array[row])
    }

或

你可以根据你的用法使用它来提取

you can use this to extract as per your usage

var selectedValue = pickerViewContent[pickerView.selectedRowInComponent(0)]

其中pickerViewContent是你的dataSource数组

where pickerViewContent is your array of dataSource
