如何在 UIDatePicker 中隐藏日期

Question

如何在 UIDatePicker 中隐藏日期并在 UIDatePicker 中添加完成按钮。

Answer 1

无法使用 UIDatePicker 实现，您必须使用自定义库或您自己创建的自定义视图。

将 MonthYearPickerView.swift 文件添加到您的项目并使用：

let monthYearPickerView = MonthYearPickerView()
monthlyPickerView.onDateSelected = { (month: Int, year: Int) in
    let string = String(format: "%02d/%d", month, year)
    NSLog(string) // should show something like 05/2015
}
monthYearPickerView.frame = CGRect(frame)
view.addSubview(monthYearPickerView)

注意：在 PickerView 顶部添加您自己的工具栏。

希望对您有所帮助。

Answer 2

无法从选择器的轮盘中完全消除日期。您可以将自己的日期选择器实现为 UIPickerView 或使用任何其他库。

您可以在自己的自定义选择器中轻松显示月份和年份。12 - 个月，即从当年算起 50 年。

    }
    func numberOfComponents(in pickerView: UIPickerView) -> Int {
        return 2
    }
    func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
        return self.pickerDaysmonth[component].count
    }
    func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
        return self.pickerDaysmonth[component][row]
    }
    func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
        let days =  pickerDaysmonth[0][pickerView.selectedRow(inComponent: 0)]
        let month = pickerDaysmonth[1][pickerView.selectedRow(inComponent: 1)]
        textField.text =   days + " " + month
    }
}
