UNUserNotificationCenter did receive response with completion handler is never called iOS10, swift 2.3
I am scheduling new notifications in iOS10, like this:
func scheduleNotification (event : Meeting, todaysBadgeCounter: Int) {
if #available(iOS 10.0, *) {
let minutesBefore = 10
//interval in seconds from current point in time to notification
let interval : NSTimeInterval = NSTimeInterval(secondsFromNowTo(event.startTime.dateByAddingTimeInterval(-minutesBefore * 60)))
//only schedule in the future
if(interval > 0){
let category = NotificationsController.notificationCategory
let center = NotificationsController.notificationCenter
center.setNotificationCategories([category])
let content = UNMutableNotificationContent()
content.title = NSString.localizedUserNotificationStringForKey(event.title, arguments: nil)
if(minutesBefore <= 1){
content.body = NSString.localizedUserNotificationStringForKey("IOS10: Your \(event.title) is about to start", arguments: nil)
}else{
content.body = NSString.localizedUserNotificationStringForKey("IOS10: You have \(event.title) in \(Int(minutesBefore)) minutes", arguments: nil)
}
content.sound = UNNotificationSound.defaultSound()
let trigger = UNTimeIntervalNotificationTrigger.init(timeInterval: interval, repeats: false)
let identifier = NSString.localizedUserNotificationStringForKey("sampleRequest\(event.UUID)", arguments: nil)
let request = UNNotificationRequest.init(identifier: identifier, content: content, trigger: trigger)
//setting the delegate
center.delegate = self
center.addNotificationRequest(request, withCompletionHandler: { (error) in
// handle the error if needed
log.error(error?.localizedDescription)
print("SCHEDULING >=iOS10:", event.title, ", interval:", interval)
})
}
//return category
@available(iOS 10.0, *)
class var notificationCategory : UNNotificationCategory {
struct Static {
static let callNow = UNNotificationAction(identifier: NotificationActions.callNow.rawValue, title: "Call now", options: [])
static let clear = UNNotificationAction(identifier: NotificationActions.clear.rawValue, title: "Clear", options: [])
static let category : UNNotificationCategory = UNNotificationCategory.init(identifier: "CALLINNOTIFICATION", actions: [callNow, clear], intentIdentifiers: [], options: [])
}
return Static.category
}
I am able to schedule notifications, and receive local notifications at the right time. BUT: my delegate methods that I used according to the tutorial are never executed, however the didReceiveLocalNotification is executed each time I tap on the notification:
extension NotificationsController: UNUserNotificationCenterDelegate {
@available(iOS 10.0, *)
func userNotificationCenter(center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: () -> Void) {
print("IOS10 delivered")
// Response has actionIdentifier, userText, Notification (which has Request, which has Trigger and Content)
switch response.actionIdentifier {
case NotificationActions.NotifyBefore.rawValue:
print("notify")
break
case NotificationActions.callNow.rawValue:
print("callNow")
break
case NotificationActions.clear.rawValue:
print("clear")
default: break
}
}
@available(iOS 10.0, *)
func userNotificationCenter(center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: (UNNotificationPresentationOptions) -> Void) {
// Delivers a notification to an app running in the foreground.
print("IOS10 delivered 2222")
}
}
Wasn't didReceiveLocalNotification deprecated? How to make these methods to be called?
UPDATE:
I updated my code with some suggestions from here, namely:
- I added assigning of the UNUserNotificationCenter.delegate to the applicationDidFinishLaunchingWithOptions.
- I also tried moving these methods (delegate methods) out of the extension to the NotificationsController.swift class, and setting this class as UNUserNotificationCenterDelegate. Did not work for me either.

Request identifier is not the notification category.
Just add this line:
content.categoryIdentifier = identifier
Update: Just made a simple app. Everything seems to working fine:
class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate {
var window: UIWindow?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
UNUserNotificationCenter.current().delegate = self
UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .badge, .sound]) { (granted, error) in
if granted {
self.registerCategory()
self.scheduleNotification(event: "test", interval: 3)
self.scheduleNotification(event: "test2", interval: 5)
}
}
return true
}
func registerCategory() -> Void{
let callNow = UNNotificationAction(identifier: "call", title: "Call now", options: [])
let clear = UNNotificationAction(identifier: "clear", title: "Clear", options: [])
let category : UNNotificationCategory = UNNotificationCategory.init(identifier: "CALLINNOTIFICATION", actions: [callNow, clear], intentIdentifiers: [], options: [])
let center = UNUserNotificationCenter.current()
center.setNotificationCategories([category])
}
func scheduleNotification (event : String, interval: TimeInterval) {
let content = UNMutableNotificationContent()
content.title = event
content.body = "body"
content.categoryIdentifier = "CALLINNOTIFICATION"
let trigger = UNTimeIntervalNotificationTrigger.init(timeInterval: interval, repeats: false)
let identifier = "id_"+event
let request = UNNotificationRequest.init(identifier: identifier, content: content, trigger: trigger)
let center = UNUserNotificationCenter.current()
center.add(request, withCompletionHandler: { (error) in
})
}
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
print("didReceive")
completionHandler()
}
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
print("willPresent")
completionHandler([.badge, .alert, .sound])
}
}
Update 2: Rewritten in Swift 2.3
class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate {
var window: UIWindow?
func applicationDidFinishLaunching(application: UIApplication) {
UNUserNotificationCenter.currentNotificationCenter().delegate = self
UNUserNotificationCenter.currentNotificationCenter().requestAuthorizationWithOptions([.Badge, .Sound, .Alert]) { (granted, error) in
if granted {
self.registerCategory()
self.scheduleNotification("test", interval: 3)
self.scheduleNotification("test2", interval: 5)
}
}
}
func registerCategory() -> Void{
let callNow = UNNotificationAction(identifier: "call", title: "Call now", options: [])
let clear = UNNotificationAction(identifier: "clear", title: "Clear", options: [])
let category : UNNotificationCategory = UNNotificationCategory.init(identifier: "CALLINNOTIFICATION", actions: [callNow, clear], intentIdentifiers: [], options: [])
let center = UNUserNotificationCenter.currentNotificationCenter()
center.setNotificationCategories([category])
}
func scheduleNotification(event : String, interval: NSTimeInterval) {
let content = UNMutableNotificationContent()
content.title = event
content.body = "body"
content.categoryIdentifier = "CALLINNOTIFICATION"
let trigger = UNTimeIntervalNotificationTrigger.init(timeInterval: interval, repeats: false)
let identifier = "id_"+event
let request = UNNotificationRequest.init(identifier: identifier, content: content, trigger: trigger)
let center = UNUserNotificationCenter.currentNotificationCenter()
center.addNotificationRequest(request) { (error) in
}
}
func userNotificationCenter(center: UNUserNotificationCenter, willPresentNotification notification: UNNotification, withCompletionHandler completionHandler: (UNNotificationPresentationOptions) -> Void) {
print("willPresent")
completionHandler([.Badge, .Alert, .Sound])
}
func userNotificationCenter(center: UNUserNotificationCenter, didReceiveNotificationResponse response: UNNotificationResponse, withCompletionHandler completionHandler: () -> Void) {
print("didReceive")
completionHandler()
}
}
