User Notification request always come with default action identifier - ios

Question

I am using the UNUserNotificationCenterDelegate (> ios 10) and one of the delegate methods where I can check the response from the notification has always actionIdentifier equal "com.apple.UNNotificationDefaultActionIdentifier" no matter what I do. The "response.notification.request.content.categoryIdentifier" comes right, with the expected value, but the request.actionIdentifier never comes correctly ("mycustomactionidentifier" in the example below). Does anyone know if I'm missing something?
extension NotificationManager: UNUserNotificationCenterDelegate {
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: #escaping (UNNotificationPresentationOptions) -> Swift.Void) {
completionHandler([.alert,.sound])
}
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: #escaping () -> Swift.Void) {
if response.notification.request.content.categoryIdentifier == "TEST" {
if response.actionIdentifier == "mycustomactionidentifier" {
NSLog("it finally works dude!")
}
}
completionHandler()
}
}
I added the action and category to the Notification center:
let uploadAction = UNNotificationAction(identifier: "mycustomactionidentifier", title: "Uploaded", options: [])
let category = UNNotificationCategory(identifier: "TEST", actions: [uploadAction], intentIdentifiers: [])
center.setNotificationCategories([category])
and am sending the request putting the correct identifier:
let uploadContent = UNMutableNotificationContent()
uploadContent.title = String(number) + " asset(s) added"
uploadContent.body = "Check your inventory to manage your assets!"
uploadContent.categoryIdentifier = "TEST"
let trigger = UNTimeIntervalNotificationTrigger(timeInterval: 6, repeats: false)
let uploadRequestIdentifier = "mycustomactionidentifier"
let uploadRequest = UNNotificationRequest(identifier: uploadRequestIdentifier, content: uploadContent, trigger: trigger)
UNUserNotificationCenter.current().add(uploadRequest, withCompletionHandler: nil)

Firstly: Register your custom actions:
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
UNUserNotificationCenter.current().delegate = self
UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .sound]) { (granted, error) in
if granted {
// Access granted
} else {
// Access denied
}
}
self.registerNotificationAction()
return true
}
func registerNotificationAction() {
let first = UNNotificationAction.init(identifier: "first", title: "Action", options: [])
let category = UNNotificationCategory.init(identifier: "categoryIdentifier", actions: [first], intentIdentifiers: [], options: [])
UNUserNotificationCenter.current().setNotificationCategories([category])
}
And create a content with a unique identifier:
func scheduleNotification() {
// Create a content
let content = UNMutableNotificationContent.init()
content.title = NSString.localizedUserNotificationString(forKey: "Some title", arguments: nil)
content.body = NSString.localizedUserNotificationString(forKey: "Body of notification", arguments: nil)
content.sound = UNNotificationSound.default()
content.categoryIdentifier = "categoryIdentifier"
// Create a unique identifier for each notification
let identifier = UUID.init().uuidString
// Notification trigger
let trigger = UNTimeIntervalNotificationTrigger.init(timeInterval: 5, repeats: false)
// Notification request
let request = UNNotificationRequest.init(identifier: identifier, content: content, trigger: trigger)
// Add request
UNUserNotificationCenter.current().add(request, withCompletionHandler: nil)
}
Lastly: Handle the notification with their default and custom actions.
extension AppDelegate: UNUserNotificationCenterDelegate {
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: #escaping () -> Void) {
if response.notification.request.content.categoryIdentifier == "categoryIdentifier" {
switch response.actionIdentifier {
case UNNotificationDefaultActionIdentifier:
print(response.actionIdentifier)
completionHandler()
case "first":
print(response.actionIdentifier)
completionHandler()
default:
break;
}
}
}
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: #escaping (UNNotificationPresentationOptions) -> Void) {
completionHandler([.alert, .sound])
}
}
Hope it helps!

Here's the results: This is going to be our UNNotificationDefaultActionIdentifier:
And this one is expanded version of the notification, we could handle both actions:

As Mannopson said, you can register a default action identifier.
However I though what you need is another thing :
response.notification.request.identifier
From Apple's actionIdentifier description said This parameter may contain one the identifier of one of your UNNotificationAction objects or it may contain a system-defined identifier. which means you need to register one, hope I am right(as I am a newbie to swift)
