我正在迁移到 NUUserNotification，但我遇到了问题，因为我正在使用新框架学习通知并且我不知道旧框架。我希望这不是重复的，因为我阅读了很多关于如何迁移的帖子和教程，但还没有找到让我理解如何应用于此案例的内容。我正在更新的代码不是我的，我花了一些时间来理解它。它是 iOS 警报 ( https://github.com/natsu1211/Alarm-ios-swift )的克隆，我将其合并到我的应用程序中，以在预定时间/日期等执行任务……我有两件事难以理解的是通知重复，据我所知，现在是每个工作日还是一次，对吗？fireDate 参数已折旧，那么我将如何重写它？：
private func minFireDateWithIndex(notifications: [UILocalNotification]) -> (Date, Int)? {
if notifications.isEmpty {
return nil
}
var minIndex = -1
var minDate: Date = notifications.first!.fireDate!
for n in notifications {
let index = n.userInfo!["index"] as! Int
if(n.fireDate! <= minDate) {
minDate = n.fireDate!
minIndex = index
}
}
return (minDate, minIndex)
}
我在更新时遇到问题的另一个代码是检查 now 的现有通知getPendingNotificationRequestsWithCompletionHandler:]。它if let n = UIApplication.shared.scheduledLocalNotifications在定义通知的旧函数中，我想我已经更新了剩余部分。旧代码：
func setupNotificationSettings() -> UIUserNotificationSettings {
var snoozeEnabled: Bool = false
if let n = UIApplication.shared.scheduledLocalNotifications {
if let result = minFireDateWithIndex(notifications: n) {
let i = result.1
snoozeEnabled = alarmModel.alarms[i].snoozeEnabled
}
}
// Specify the notification types.
let notificationTypes: UIUserNotificationType = [UIUserNotificationType.alert, UIUserNotificationType.sound]
// Specify the notification actions.
let stopAction = UIMutableUserNotificationAction()
stopAction.identifier = Id.stopIdentifier
stopAction.title = "OK"
stopAction.activationMode = UIUserNotificationActivationMode.background // choose activation mode for app on tapping notification
stopAction.isDestructive = false
stopAction.isAuthenticationRequired = false
let snoozeAction = UIMutableUserNotificationAction()
snoozeAction.identifier = Id.snoozeIdentifier
snoozeAction.title = "Snooze"
snoozeAction.activationMode = UIUserNotificationActivationMode.background
snoozeAction.isDestructive = false
snoozeAction.isAuthenticationRequired = false
let actionsArray = snoozeEnabled ? [UIUserNotificationAction](arrayLiteral: snoozeAction, stopAction) : [UIUserNotificationAction](arrayLiteral: stopAction)
let actionsArrayMinimal = snoozeEnabled ? [UIUserNotificationAction](arrayLiteral: snoozeAction, stopAction) : [UIUserNotificationAction](arrayLiteral: stopAction)
// Specify the category related to the above actions.
let alarmCategory = UIMutableUserNotificationCategory()
alarmCategory.identifier = "myAlarmCategory"
alarmCategory.setActions(actionsArray, for: .default)
alarmCategory.setActions(actionsArrayMinimal, for: .minimal)
let categoriesForSettings = Set(arrayLiteral: alarmCategory)
// Register the notification settings.
let newNotificationSettings = UIUserNotificationSettings(types: notificationTypes, categories: categoriesForSettings)
UIApplication.shared.registerUserNotificationSettings(newNotificationSettings)
return newNotificationSettings
}
新代码编辑：
func setRouteNotification(_ date: Date, onWeekdaysForNotify weekdays:[Int], snoozeEnabled:Bool, onSnooze: Bool, soundName: String, routeName: String, index: Int) {
// Notification content
let routeCheckNotificationContent = UNMutableNotificationContent()
let datesForNotification = correctDate(date, onWeekdaysForNotify: weekdays)
routeCheckNotificationContent.title = "Hello!! Are you ready to cycle?"
routeCheckNotificationContent.body = "Check route for alerts?"
routeCheckNotificationContent.categoryIdentifier = Id.notificationCategory
routeCheckNotificationContent.sound = UNNotificationSound.init(named: soundName + ".mp3") // check for the + ".mp3"
// Define actions
let check = UNNotificationAction(identifier: Id.checkActionIdentifier, title: " Check", options: [.foreground])
let wait = UNNotificationAction(identifier: Id.waitActionIdentifier, title: "Wait", options: [])
// Define category
let routeCategory = UNNotificationCategory(identifier: Id.notificationCategory, actions: [check, wait], intentIdentifiers: [], options: [])
// Register category
UNUserNotificationCenter.current().setNotificationCategories([routeCategory])
let repeating: Bool = !weekdays.isEmpty
routeCheckNotificationContent.userInfo = ["snooze" : snoozeEnabled, "index": index, "soundName": soundName, "routeName": routeName, "repeating" : repeating]
//repeat weekly if repeat weekdays are selected
//no repeat with snooze notification
if !weekdays.isEmpty && !onSnooze{
}
syncAlarmModel()
for d in datesForNotification {
if onSnooze {
alarmModel.alarms[index].date = Scheduler.correctSecondComponent(date: alarmModel.alarms[index].date)
}
else {
alarmModel.alarms[index].date = d
}
// Notification trigger
let calendar = Calendar(identifier: .gregorian)
let components = calendar.dateComponents(in: .current, from: d)
let newComponents = DateComponents(calendar: calendar, timeZone: .current, month: components.month, day: components.day, hour: components.hour, minute: components.minute, second: components.second, weekday: components.weekday)
let trigger = UNCalendarNotificationTrigger(dateMatching: newComponents, repeats: true)
// Notification Request
let routeNotificationRequest = UNNotificationRequest(identifier: "routeNotificationRequest", content: routeCheckNotificationContent, trigger: trigger)
// Add request
UNUserNotificationCenter.current().add(routeNotificationRequest) { (Error) in
if Error != nil {
print("something went wrong with adding notification")
}
}
}
}
var weekdays: [Int]!是一个填充在 WeekdaysViewController ( a TableViewController ) 中的数组，用于选择行。
现在，当我选择任何一天时，都不会触发通知。
