Question

我正在使用以下代码：

    // Disallow sundays, after 8pm and before 8am
    if weekday == 1 {
        datePicker.setDate(Date(timeInterval: 60*60*24*1, since: datePicker.date), animated: true)
    }

    if hour >= 20 && minute > 0 {
        let calendar = Calendar.current
        var components = DateComponents()
        components.hour = 9
        components.minute = 00
        datePicker.setDate(calendar.date(from: components)!, animated: false)
    }

    if hour < 8 {
       let calendar = Calendar.current
       var components = DateComponents()
       components.hour = 9
       components.minute = 00
       datePicker.setDate(calendar.date(from: components)!, animated: false)
    }

我想在星期日上午8点之前和晚上8点之后封锁几个星期天。如果有人选择的时间不在我们的开放时间之内，则应滚动到有效时间。该代码无法正常运行，因为它将回滚至1月1日？

我对此进行了很多尝试，都没有结果。

我认为最好确定封闭时间是在午夜之前还是之后，然后根据该时间以不同的方式计算新日期

let calendar = Calendar.current
if weekday == 1 || 20...23 ~= hour {
    if let next = calendar.date(byAdding: .day, value: 1, to: date),
        let opening = calendar.date(bySettingHour: 9, minute: 0, second: 0, of: next) {
        datePicker.setDate(opening)
    }
} else if 0..<8 ~= hour {
    if let opening = calendar.date(bySettingHour: 9, minute: 0, second: 0, of: date) {
        datePicker.setDate(opening)
    }
}

DatePicker禁用星期日+营业时间
