Я пытаюсь перенести уведомление, когда пользователь нажимает на действие ожидания уведомления. Когда triggerNotification() вызывается в первый раз, Date предоставляется средством выбора даты, но когда он вызывается ответом, получает дату из временного интервала. Внутри didReceiveResponse метода case:waitActionIdentifier: я устанавливаю newDate и передаю его параметру triggerNotification. Отложенное уведомление никогда не приходит.
Я не понимаю, если это проблема с вызовом функции, или потому что newDate я вижу, правильно, печать его.
Вот код:
class ViewController: UIViewController {
@IBAction func datePickerDidSelectNewDate(_ sender: UIDatePicker) {
let selectedDate = sender.date
let delegate = UIApplication.shared.delegate as? AppDelegate
// delegate?.scheduleNotification(at: selectedDate)
delegate?.triggerNotification(at: selectedDate)
}
}
и AppDelegate
import UIKit
import UserNotifications
@UIApplicationMain class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate {
var window: UIWindow?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
UNUserNotificationCenter.current().delegate = self
configureCategory()
triggerNotification(at: Date())
requestAuth()
return true
}
let category = "Notification.Category.Read"
private let readActionIdentifier = "Read"
private let waitActionIdentifier = "Wait"
private func requestAuth() {
UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .sound, .badge]) { (success, error) in
if let error = error {
print("Request Authorization Failed (\(error), \(error.localizedDescription))")
}
}
}
func triggerNotification(at date: Date) {
// Create Notification Content
let notificationContent = UNMutableNotificationContent()
//compone a new Date components because components directly from Date don't work
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)
//create the trigger with above new date components, with no repetitions
let trigger = UNCalendarNotificationTrigger(dateMatching: newComponents, repeats: false)
// Configure Notification Content
notificationContent.title = "Hello"
notificationContent.body = "Kindly read this message."
// Set Category Identifier
notificationContent.categoryIdentifier = category
// Add Trigger
// let notificationTrigger = UNTimeIntervalNotificationTrigger(timeInterval: 10.0, repeats: false)
// // Create Notification Request
let notificationRequest = UNNotificationRequest(identifier: "test_local_notification", content: notificationContent, trigger: trigger)
//
// Add Request to User Notification Center
UNUserNotificationCenter.current().add(notificationRequest) { (error) in
if let error = error {
print("Unable to Add Notification Request (\(error), \(error.localizedDescription))")
}
}
}
private func configureCategory() {
// Define Actions
let read = UNNotificationAction(identifier: readActionIdentifier, title: "Read", options: [])
