根据用户输入的日期快速启用和禁用过去的时间选择器

Question

在我的情况下，我正在验证用户输入的当前date或基于它的其他日期，我需要在时间选择器中启用和禁用过去的时间限制。如果用户输入当前日期，则需要限制过去的时间picker，否则需要显示所有time列表。

下面的我的代码

// MARK: Validate Current Date or Not Based on it Need to enable and disable timepicker past time

        let dateCurrents = Date()
        let formatters = DateFormatter()
        formatters.dateFormat = "yyyy-MM-dd"
        let resultDate = formatters.string(from: dateCurrents)

        if fullDate == resultDate {
            print("Same Date Past Time Disabled")
            let nows = Date()
            timePickerView.minimumDate = nows
            timePickerView.date = nows
        } else {
            print("Different Date Past Time Enabled")
            timePickerView.minimumDate =
            timePickerView.date =  // Need to Enable Past Time
        }

Answer 1

您可以执行以下操作：

let fullDate = datePickerView.date
let now = Date()

let calendar = Calendar.current
let result = calendar.compare(now, to: fullDate, toGranularity: .day)
let isSameDay = result == .orderedSame

if isSameDay {
    print("Same Date Past Time Disabled")
    timePickerView.minimumDate = now
    timePickerView.date = now
} else {
    print("Different Date Past Time Enabled")
    timePickerView.minimumDate = nil
    timePickerView.date = now
}
