【中文标题】在 UNNotification 我得到的 userInfo 值与 UNNotificationRequest Swift 中的设置值不同【英文标题】:at UNNotification I get different userInfo values than set values in UNNotificationRequest Swift 【发布时间】:2019-03-19 08:08:32 【问题描述】:我有一个函数可以设置UNNotificationRequest
并传入一些参数,然后我将这些参数放入userInfo
,这样我就可以在打开本地通知时取回它们并使用它们。它的打印显示我正在分配正确的传入值。问题是当我在applicationDidBecomeActive
中打印userInfo
时,我得到了一些其他值。我不明白为什么会这样,你能发现我在这里做错了什么吗?
这是设置通知和输出打印的function
:
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.title = "Ciao!! Pronto ad andare?"
// routeCheckNotificationContent.body = "Check route for alerts?"
routeCheckNotificationContent.body = "Controlliamo se ci sono ostacoli lungo il tuo percorso?"
routeCheckNotificationContent.categoryIdentifier = Id.notificationCategory
routeCheckNotificationContent.sound = UNNotificationSound.init(named: soundName + ".mp3")
print(" set notification is: date: \(date), onWeekdaysForNotify : \(weekdays), snoozeEnabled : \(snoozeEnabled), onSnooze: \(onSnooze), soundName: \(soundName), routeName: \(routeName), index: \(index)")
let repeating: Bool = !weekdays.isEmpty
// routeCheckNotificationContent.userInfo = ["snooze" : snoozeEnabled, "index": index, "soundName": soundName, "routeName": routeName, "repeating" : repeating]
routeCheckNotificationContent.userInfo = ["posticipa" : snoozeEnabled, "indice": index, "Suono": soundName, "Titolo percorso" : String(describing: routeName), "repeating" : repeating]
print("routeCheckNotificationContent.userInfo at setting notification is: \(routeCheckNotificationContent.userInfo)")
//repeat weekly if repeat weekdays are selected
//no repeat with snooze notification
if !weekdays.isEmpty && !onSnooze
syncAlarmModel()
var counter = 0
for d in datesForNotification
if onSnooze
alarmModel.alarms[index].date = Scheduler.correctSecondComponent(date: alarmModel.alarms[index].date)
else
alarmModel.alarms[index].date = d
//trigger
let components = Calendar.current.dateComponents([.weekday,.hour,.minute,.second,], from: d)
let trigger = UNCalendarNotificationTrigger(dateMatching: components, repeats: true)
// Notification Request
let uuid = UUID().uuidString
let routeNotificationRequest = UNNotificationRequest(identifier: "Route Notification Request\(uuid)", 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\(uuid)")
scheduledNotifications.append(counter)
// print("scheduled notifications are \(scheduledNotifications.count)")
counter = ( counter + 1 )
// print(alarmModel.alarms)
// print("dates for notification are: \(datesForNotification)")
输出打印:
routeCheckNotificationContent.userInfo at setting notification is: [AnyHashable("repeating"): true, AnyHashable("indice"): 0, AnyHashable("Titolo percorso"): "aaa", AnyHashable("Suono"): "Zen", AnyHashable("posticipa"): false]
但在AppDelegate
:
func applicationDidBecomeActive(_ application: UIApplication)
let center = UNUserNotificationCenter.current()
center.getDeliveredNotifications (receivedNotifications) in
for notification in receivedNotifications
let content = notification.request.content
print(" Body \(content.body)")
print(" Title \(content.title)")
let rotta = content.userInfo["Titolo percorso"]
print("rotta is: \(rotta)")
print(content.userInfo as NSDictionary)
// Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.
// audioPlayer?.play()
// alarmScheduler.checkNotification()
输出打印:
Body Controlliamo se ci sono ostacoli lungo il tuo percorso?
Title Ciao!! Pronto ad andare?
rotta is: Optional(Scegli un percorso)
Suono = Suono;
"Titolo percorso" = "Scegli un percorso";
indice = 0;
posticipa = 0;
repeating = 0;
正文和标题是正确的,但其余的不是……我在哪里缺少这些错误值的连接? 像往常一样非常感谢
更新:
我从我设置这些值的每个地方都制作了一些新的打印件,它们都是正确的,但是在AppDelegate
i 中,我从这一行得到了值:
addEditController.segueInfo = SegueInfo(curCellIndex: alarmModel.count, isEditMode: false, label: "Percorso", mediaLabel: "Suono", mediaID: "", routeLabel: "Scegli un percorso", repeatWeekdays: [], enabled: false, snoozeEnabled: false)
SegueInfo 只是一个结构,它保存值直到它们被实际选择的值替换,我确实更新它们..
struct SegueInfo
var curCellIndex: Int
var isEditMode: Bool
var label: String
var mediaLabel: String
var mediaID: String
var routeLabel: String
// var routeId: String
var repeatWeekdays: [Int]
var enabled: Bool
var snoozeEnabled: Bool
【问题讨论】:
【参考方案1】:我终于找到了问题所在。我没有得到响应中的值。所以我从applicationDidBecomeActive
中删除了代码,并在适当的Action 中从didReceive response
中获取了值,它现在按预期工作。
我希望这对其他人有帮助。
整个函数是:
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void)
switch response.actionIdentifier
case Id.checkActionIdentifier:
print("Check tapped")
let content = response.notification.request.content
let rotta = content.userInfo["Titolo percorso"] as! String
RoutesArray.routeName = rotta
print("rotta is: \(rotta)")
print(" Body \(content.body)")
print(" Title \(content.title)")
NewMapViewController.checkCounter = 1
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let initialViewController : UINavigationController = storyboard.instantiateViewController(withIdentifier: "MainNavigationController") as! UINavigationController
self.window?.rootViewController = initialViewController
self.window?.makeKeyAndVisible()
let vc = initialViewController.viewControllers[0]
vc.performSegue(withIdentifier: "alertToMapSegue", sender: nil)
case Id.waitActionIdentifier:
print("Wait tapped")
default:
print("Other Action")
completionHandler()

是否可以在一定时间后使 UNNotification 过期或消失?
