swift - 使用相同的个性化键盘填充不同的UITextField

Question

我有一个 View ，其中有不同的UITextfield。为了填充这个 TF，我使用个性化的 UIPickerview 作为键盘。

我的问题是，当我选择第一个 TF 时，键盘打开，我可以选择我的值。该值将转到该选定的 TF。现在，当我选择第二个 TF 时，键盘会出现，但值会转到第一个 TF ...

我不知道为什么这不起作用......

在我的ViewDidLoad中得到:

flightTimeSe.inputAccessoryView = Ttoolbar
flightTimeSe.delegate = self
flightTimeMe.inputView = DurationPicker
flightTimeMe.inputAccessoryView = Ttoolbar
flightTimeMe.delegate = self
flightTimeMp.inputView = DurationPicker

这会将 UIPickerview 分配给 TF 和我的工具栏。

我的UIPickerview定义如下:

lazy var DurationPicker: UIPickerView = {
        let DurationPicker = UIPickerView()
        DurationPicker.delegate = self
        DurationPicker.dataSource = self

        var flightTime: String = ""
        var row0: String = "0"
        var row1: String = "0"
        var row2: String = "0"
        var row4: String = "0"
        var row5: String = "0"

            row0 = myPickerRow1[DurationPicker.selectedRow(inComponent: 0)]

            row1 = myPickerRow2[DurationPicker.selectedRow(inComponent: 1)]

            row2 = myPickerRow3[DurationPicker.selectedRow(inComponent: 2)]

            row4 = myPickerRow5[DurationPicker.selectedRow(inComponent: 4)]

            row5 = myPickerRow6[DurationPicker.selectedRow(inComponent: 5)]

        //print("\(row0)\(row1)\(row2):\(row4)\(row5)")

        if row0 != "0"{
            flightTime = "\(row0)\(row1)\(row2):\(row4)\(row5)"
        }else if row0 == "0" && row1 != "0"  {
            flightTime = "\(row1)\(row2):\(row4)\(row5)"
        }else if row1 == "0" && row2 != "0"  {
            flightTime = "\(row2):\(row4)\(row5)"
        }else if row2 == "0" && row4 != "0"  {
            flightTime = "\(row2):\(row4)\(row5)"
        }else if row2 == "0" && row4 == "0" && row5 != "0" {
            flightTime = "\(row2):\(row4)\(row5)"
        }
        print(flightTime)
        return DurationPicker
    }()

我现在不知道如何处理我的委托(delegate)来填补正确的 TF...

感谢您的帮助!

更好的方法是创建一个函数，它接受文本字段和标签，创建 UIPickerView 对象并设置为文本字段的输入 View ，在创建时您可以将标签分配给 UIPickerView，在委托(delegate)中您可以读取日期选择器的标签并相应地更新文本字段。
