Существует метод делегирования для отображения уведомления, когда приложение открыто в iOS 10. Вам нужно реализовать это, чтобы получать богатые уведомления, когда приложение открыто.
extension ViewController: UNUserNotificationCenterDelegate {
//for displaying notification when app is in foreground
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
//If you don't want to show notification when app is open, do something here else and make a return here.
//Even you you don't implement this delegate method, you will not see the notification on the specified controller. So, you have to implement this delegate and make sure the below line execute. i.e. completionHandler.
completionHandler([.alert, .badge, .sound])
}
// For handling tap and user actions
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
switch response.actionIdentifier {
case "action1":
print("Action First Tapped")
case "action2":
print("Action Second Tapped")
default:
break
}
completionHandler()
}
}
Чтобы запланировать уведомление в iOS 10 и предоставить значок
override func viewDidLoad() {
super.viewDidLoad()
// set UNUserNotificationCenter delegate to self
UNUserNotificationCenter.current().delegate = self
scheduleNotifications()
}
func scheduleNotifications() {
let content = UNMutableNotificationContent()
let requestIdentifier = "rajanNotification"
content.badge = 1
content.title = "This is a rich notification"
content.subtitle = "Hello there, I am Rajan Maheshwari"
content.body = "Hello body"
content.categoryIdentifier = "actionCategory"
content.sound = UNNotificationSound.default()
// If you want to attach any image to show in local notification
let url = Bundle.main.url(forResource: "notificationImage", withExtension: ".jpg")
do {
let attachment = try? UNNotificationAttachment(identifier: requestIdentifier, url: url!, options: nil)
content.attachments = [attachment!]
}
let trigger = UNTimeIntervalNotificationTrigger.init(timeInterval: 3.0, repeats: false)
let request = UNNotificationRequest(identifier: requestIdentifier, content: content, trigger: trigger)
UNUserNotificationCenter.current().add(request) { (error:Error?) in
if error != nil {
print(error?.localizedDescription)
}
print("Notification Register Success")
}
}
Чтобы зарегистрироваться в AppDelegate, мы должны написать этот фрагмент кода в didFinishLaunchingWithOptions
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
registerForRichNotifications()
return true
}
Я также определил действия здесь. Вы можете пропустить их
func registerForRichNotifications() {
UNUserNotificationCenter.current().requestAuthorization(options: [.alert,.badge,.sound]) { (granted:Bool, error:Error?) in
if error != nil {
print(error?.localizedDescription)
}
if granted {
print("Permission granted")
} else {
print("Permission not granted")
}
}
//actions defination
let action1 = UNNotificationAction(identifier: "action1", title: "Action First", options: [.foreground])
let action2 = UNNotificationAction(identifier: "action2", title: "Action Second", options: [.foreground])
let category = UNNotificationCategory(identifier: "actionCategory", actions: [action1,action2], intentIdentifiers: [], options: [])
UNUserNotificationCenter.current().setNotificationCategories([category])
}
Если вы хотите, чтобы ваше уведомление баннер должен быть показаны везде во всем приложении, то вы можете написать делегатый UNUserNotificationDelegate
в AppDelegate
и сделать UNUserNotificationCenter
текущего делегата AppDelegate
extension AppDelegate: UNUserNotificationCenterDelegate {
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
print(response.notification.request.content.userInfo)
completionHandler()
}
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
completionHandler([.alert, .badge, .sound])
}
}
