如何在iOS 10 UserNotifications上设置NSCalendarUnitMinute repeatInterval？

问题描述

在UILocalNotification中，我们使用 NSCalendarUnitMinute 重复.....但我在iOS 10中找不到 UserNotification doc ...如何使用 NSCalendarUnitMinute 像iOS 10中的重复 UserNotification ？

In UILocalNotification we use NSCalendarUnitMinute like repetition ..... but I can't find in iOS 10 UserNotification doc ... How can I use NSCalendarUnitMinute like repetition in iOS 10 UserNotification?

这里的代码将在晚上8:30安排本地通知，并会在每一分钟后重复。

here is the code which will schedule local notification at 8:30 pm and will repeat after every one minute.

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];

推荐答案

虽然看来旧的通知框架有更好的支持关于这一点，直到我们才意识到新的更好!!

Although it appears that the old notifications framework had better support regarding this, it's only until, we realise that the new one is better!!

我遇到了类似的问题，下面是旧通知如何发挥作用的示例与新的一起。

I had similar problems, and below is a sample of how the old notifications can go hand in hand with the new ones.

为了更安全，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
            }
        }
    }

虽然这并非详尽无遗，但我几乎从一分钟到一年不等。

Although this isn't exhaustive, I've pretty much covered everything from a minute to a year.

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，所以应该为你们其他人。如果有问题，请尝试让我知道。

As this works for me, it should probably for the rest of you. Please try and let me know if there is an issue.
