ios - 如何在 iOS 10 UserNotifications 上设置 NSCalendarUnitMinute repeatInterval？

Question

在 UILocalNotification 中，我们像重复一样使用 NSCalendarUnitMinute ..... 但我在 iOS 10 中找不到 UserNotification doc ...如何在 iOS 10 UserNotification 中像重复一样使用 NSCalendarUnitMinute？

这是将在晚上 8:30 安排本地通知并每隔一分钟重复一次的代码。

UILocalNotification* localNotification = [[UILocalNotification alloc] init];
localNotification.fireDate = pickerDate;
localNotification.alertBody = self.textField.text;
localNotification.timeZone = [NSTimeZone defaultTimeZone];
localNotification.repeatInterval = NSCalendarUnitMinute;
localNotification.applicationIconBadgeNumber = [[UIApplication sharedApplication] applicationIconBadgeNumber] + 1;
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];

虽然看起来旧的通知框架对此有更好的支持，但直到我们意识到新的更好!

我遇到了类似的问题，下面是旧通知如何与新通知齐头并进的示例。

为了安全起见，这是Swift2.3。

// Retrieve interval to be used for repeating the notification
    private func retrieveRepeatInterval(repeatTemp: RepeatInterval) {
        switch repeatTemp {
        case .Never:
            if #available(iOS 10.0, *) {
                toDateComponents = NSCalendar.currentCalendar().components([.Hour, .Minute, .Day, .Month, .Year], fromDate: timeTemp!)
                toDateComponents.second = 0
                repeatNotification = false
            } else {
                repeatIntervalTemp = nil
            }
        case .EveryMinute:
            if #available(iOS 10.0, *) {
                toDateComponents.second = 0
                repeatNotification = true
            } else {
                repeatIntervalTemp = .Minute
            }
        case .EveryHour:
            if #available(iOS 10.0, *) {
                toDateComponents = NSCalendar.currentCalendar().components([.Minute], fromDate: timeTemp!)
                toDateComponents.second = 0
                repeatNotification = true
            } else {
                repeatIntervalTemp = .Hour
            }
        case .EveryDay:
            if #available(iOS 10.0, *) {
                toDateComponents = NSCalendar.currentCalendar().components([.Hour, .Minute], fromDate: timeTemp!)
                toDateComponents.second = 0
                repeatNotification = true
            } else {
                repeatIntervalTemp = .Day
            }
        case .EveryWeek:
            if #available(iOS 10.0, *) {
                toDateComponents = NSCalendar.currentCalendar().components([.Hour, .Minute, .Weekday], fromDate: timeTemp!)
                toDateComponents.second = 0
                repeatNotification = true
            } else {
                repeatIntervalTemp = .WeekOfYear
            }
        case .EveryMonth:
            if #available(iOS 10.0, *) {
                toDateComponents = NSCalendar.currentCalendar().components([.Hour, .Minute, .Day], fromDate: timeTemp!)
                toDateComponents.second = 0
                repeatNotification = true
            } else {
                repeatIntervalTemp = .Month
            }
        case .EveryYear:
            if #available(iOS 10.0, *) {
                toDateComponents = NSCalendar.currentCalendar().components([.Hour, .Minute, .Day, .Month], fromDate: timeTemp!)
                toDateComponents.second = 0
                repeatNotification = true
            } else {
                repeatIntervalTemp = .Year
            }
        }
    }

虽然这并不详尽，但我几乎涵盖了从一分钟到一年的所有内容。

更详细一点，

// RepeatInterval
enum RepeatInterval : String, CustomStringConvertible {
    case Never = "Never"
    case EveryMinute = "Every Minute"
    case EveryHour = "Every Hour"
    case EveryDay = "Every Day"
    case EveryWeek = "Every Week"
    case EveryMonth = "Every Month"
    case EveryYear = "Every Year"

    var description : String { return rawValue }

    static let allValues = [Never, EveryMinute, EveryHour, EveryDay, EveryWeek, EveryMonth, EveryYear]
}

var repeatTemp: RepeatInterval?

var repeatIntervalTemp: NSCalendarUnit?

var timeTemp: NSDate?

var toDateComponents = NSDateComponents()

因为这对我有用，所以它可能对你们其他人也适用。如果有问题，请尝试让我知道。

而且，对于这个问题的确切解决方案，我建议如下。

(大概苹果没有想过这样的场景，但是可以处理)

1. 安排晚上 8:30 的通知
2. 当通知被触发时，将其移除并安排另一个具有不同标识符的通知，用于上面显示的 NSCalendarUnitMinute 等价物。
3. 瞧，成功了!! (或者没有？)
