unusernotificationcenter

问题 I know there are plenty of similar questions and answers, and I reviewed them all, but still cannot find the solution. Despite of removing a scheduled notification from UNUserNotificationCenter it still gets triggered. I create local notification as follows: let aDF = DateFormatter() aDF.dateFormat = "yyyy-MM-dd HH:mm:ss" var identifierST = "" if update == true { identifierST = myCoreDataEntity.notificationUID! } else { identifierST = aDF.string(from: Date()) } let notif =

问题 So I am very new to Swift and I'm currently setting a repeating timer every 30 min after the app was launched, but i would like to only send notification between 8 am and 8 pm. Is it possible to do this without setting a reminder for each specific time? This is how I'm currently doing this. override func viewDidLoad(){ let notificationCenter = UNUserNotificationCenter.current() notificationCenter.requestAuthorization(options: [.alert, .sound]) { (granted, error ) in // enable or disable if

问题 I want a notification to show every 60 seconds. It only happened once on MacOS. The same exact code works normally on iOS. If I manually remove the notification from macOS notification center, it'll eventually show again. So the problem seems like notification won't show again if it's already showed once and the user didn't take any action. Did I miss something obvious here? Current macOS: 10.15.4 Current iOS: 13.4.1 on App Delegate func userNotificationCenter(_ center:

问题 I am making a music-streaming alarm clock. Music streams for the duration selected by the user, including in the background, and at the end of the duration a custom alarm sound is played in addition to a local notification. In short (1) set timer (2) local notification fires off (3) streamed music stops (4) alarm plays I am able to do (1) and (2) ok, but am unable to figure out how to trigger (3) or (4) when the app is in the background. Here is the code for (1) and (2) let center =

问题 How to repeat LocalNotification every 5 days at 10:00 AM I try this, but it's not working let content = UNMutableNotificationContent() content.title = "Hello!" content.body = "Hello_message_body" content.sound = UNNotificationSound.default() let futureTime = Date().addingTimeInterval(5 * 24 * 60 * 60) var calendar = NSCalendar.current calendar.timeZone = NSTimeZone.system var components = calendar.dateComponents([.hour, .minute, .second], from: futureTime) components.hour = 10 components

问题 This is a part of my code. I want to use UNUserNotificationCenter and UNUserNotificationCenterDelegate to handle notification events. This code catches the notification event when the app is in a foreground state. But "didReceive" is not fired for a background state. func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool { UNUserNotificationCenter.current().delegate = self application

问题 I'm working on local notifications but the problem I have is that the method didReceive Response is not being called when the app is terminated so when I tap on a notification action it just launches the app and did nothing else. But when the app is just in the background everything works as usual. Anything wrong with my code? //MyClassNameViewController.swift override func viewDidLoad() { super.viewDidLoad() UNUserNotificationCenter.current().delegate = self } func triggerAlarm1() { //
