I'm migrating to NUUserNotification but I'm having problems as I'm learning notifications with the newer framework and I don't know the older. I hope this is not some duplicate as I read a lot of posts and tutorial to how to migrate but haven't found something that made me understand how to apply to this case. The code I'm updating is not mine and took me time understanding it. It's a clone of the iOS Alarm ( https://github.com/natsu1211/Alarm-ios-swift) that I incorporate in my app to perform things at scheduled time/days etc etc... The two things I'm having trouble to understand are the notification repetitions, as far as I understood is now for every week day or a single time right? The fireDate parameter is depreciated so how would I rewrite this? :
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)
}
The other code I'm having trouble updating is the checking for existing notifications that now getPendingNotificationRequestsWithCompletionHandler:]. It's if let n = UIApplication.shared.scheduledLocalNotificationsinside the old function that define the notification, that I think I have updated for the remaining part.
Old code:
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
}
New code edit:
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]!is an array populated in WeekdaysViewController ( a TableViewController ), selecting the rows.
Now when I select any day, notification won't fire.
