仅触发最后添加的通知
Only last added notification gets triggered
我正在为我的类似闹钟的应用更新 UNUserNotification 框架的通知，我以为我成功了，但我意识到当我设置多个闹钟时我只得到最新的通知。重复的日子正在努力。
会不会是触发器标识符的问题，它正在获取与以前的字符串相同的字符串并覆盖它？
我真的不明白这种行为，我找不到问题出在哪里。
这是代码：
func setRouteNotification(_ date: Date, onWeekdaysForNotify weekdays:[Int], snoozeEnabled:Bool, onSnooze: Bool, soundName: String, routeName: String, index: Int) {
configureCategory()
// 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")
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()
var counter = 1
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)
let trigger = UNCalendarNotificationTrigger(dateMatching: newComponents, repeats: true)
// Notification Request
let routeNotificationRequest = UNNotificationRequest(identifier: "routeNotificationRequest\(scheduledNotifications.count + counter)", content: routeCheckNotificationContent, trigger: trigger)
// Add request
UNUserNotificationCenter.current().add(routeNotificationRequest) { (Error) in
if Error != nil {
print("something went wrong with adding notification")
}
}
print("added request\(alarmModel.alarms.count + weekdays.count + counter)")
scheduledNotifications.append(counter)
print("scheduled notifications are \(scheduledNotifications.count)")
counter = ( counter + 1 )
}
print(alarmModel.alarms)
}
知道为什么不设置所有已编程的通知吗？
像往常一样非常感谢。
编辑：
我尝试设置一个数组 var scheduledNotifications: [Int] = [] 在添加通知时存储一个累进数字，并将其用作请求的标识符
let routeNotificationRequest = UNNotificationRequest(identifier: "routeNotificationRequest\(scheduledNotifications.count + counter)", content: routeCheckNotificationContent, trigger: trigger)
所以我确定所有添加的通知都有一个唯一的请求标识符，但没有任何改变，仍然只收到最新的通知。

我使用当前日期（以秒为单位）作为标识符，它对我来说效果很好，如下所示：
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
UNUserNotificationCenter.current().requestAuthorization(options: []) { (granted, error) in
if granted {
let routeCheckNotificationContent = UNMutableNotificationContent()
routeCheckNotificationContent.title = "Hello!! Are you ready to cycle?"
routeCheckNotificationContent.body = "Check route for alerts?"
routeCheckNotificationContent.categoryIdentifier = "\(Date().timeIntervalSince1970)"
routeCheckNotificationContent.sound = UNNotificationSound.default()
routeCheckNotificationContent.userInfo = ["snooze" : false, "index": 1, "soundName": "1", "routeName": "hmm", "repeating" : true]
self.addNotification(content: routeCheckNotificationContent, date: Date().addingTimeInterval(30))
self.addNotification(content: routeCheckNotificationContent, date: Date().addingTimeInterval(60))
} else {
print("Notification permission dendied !!")
}
}
}
func addNotification(content: UNMutableNotificationContent, date: Date) {
let calendar = Calendar(identifier: .gregorian)
let components = calendar.dateComponents(in: .current, from: date)
let newComponents = DateComponents(calendar: calendar, timeZone: .current, month: components.month, day: components.day, hour: components.hour, minute: components.minute, second: components.second)
let trigger = UNCalendarNotificationTrigger(dateMatching: newComponents, repeats: true)
// Notification Request
let routeNotificationRequest = UNNotificationRequest(identifier: "\(date.timeIntervalSince1970)", content: content, trigger: trigger)
// Add request
UNUserNotificationCenter.current().add(routeNotificationRequest) { (Error) in
if Error != nil {
print("something went wrong with adding notification")
}
}
}
可能是你的日期有问题！
在尝试了不同的方法后，我想我已经解决了它，但我不明白为什么它不能像我那样工作。 d 是从 setRouteNotification 函数中的 for in 循环中获取的日期值，表示要安排通知的工作日（请参阅问题中的代码）
工作：
let components2 = Calendar.current.dateComponents([.weekday,.hour,.minute,.second,], from: d)
let trigger2 = UNCalendarNotificationTrigger(dateMatching: components2, repeats: true)
不工作：
let calendar = Calendar(identifier: .gregorian)
let components = calendar.dateComponents(in: .current, from: d)
var 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)
我遇到了同样的问题并意识到它正在发生，因为我对多个通知使用相同的标识符@"ID"。当我使标识符唯一时，它们都被触发了。
UNNotificationRequest *request = [UNNotificationRequest requestWithIdentifier:@"ID" content:notification trigger:trigger];
我正在为我的类似闹钟的应用更新 UNUserNotification 框架的通知，我以为我成功了，但我意识到当我设置多个闹钟时我只得到最新的通知。重复的日子正在努力。 会不会是触发器标识符的问题，它正在获取与以前的字符串相同的字符串并覆盖它？ 我真的不明白这种行为，我找不到问题出在哪里。
这是代码：
func setRouteNotification(_ date: Date, onWeekdaysForNotify weekdays:[Int], snoozeEnabled:Bool, onSnooze: Bool, soundName: String, routeName: String, index: Int) {
configureCategory()
// 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")
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()
var counter = 1
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)
let trigger = UNCalendarNotificationTrigger(dateMatching: newComponents, repeats: true)
// Notification Request
let routeNotificationRequest = UNNotificationRequest(identifier: "routeNotificationRequest\(scheduledNotifications.count + counter)", content: routeCheckNotificationContent, trigger: trigger)
// Add request
UNUserNotificationCenter.current().add(routeNotificationRequest) { (Error) in
if Error != nil {
print("something went wrong with adding notification")
}
}
print("added request\(alarmModel.alarms.count + weekdays.count + counter)")
scheduledNotifications.append(counter)
print("scheduled notifications are \(scheduledNotifications.count)")
counter = ( counter + 1 )
}
print(alarmModel.alarms)
}
