Question

我认为我的UITextfield与众不同。要过滤此TF，我使用个性化的UIPickerview作为键盘。

我的问题是，当我选择First TF时，键盘打开了，我可以选择我的值。值转到该选定的TF。现在，当我选择第二个TF时，会出现键盘，但值将移到第一个TF ...

我不知道为什么这行不通...

在我的ViewDidLoad中，有：

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

这将UIPickerview分配给TF以及我的工具栏。

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
    }()

我现在不该如何与我的代表打交道以填补合适的TF ...

感谢您的帮助！

更好的方法是创建一个使用文本字段和标签的函数，创建UIPickerView对象并设置为文本字段的输入视图，同时创建时可以将标签分配给UIPickerView，在委托中您可以读取日期选择器的标签并相应地更新文本字段。

使用相同的个性化键盘填充不同的UITextField
