I developed local Notifications
in iOS 10
. It is working perfectly. But now how should i code local notifications
and push notification
if user is using iOS 9
and above versions. Can anyone help please?
Below is code in iOS 10
import UIKit
import UserNotifications
@available(iOS 10.0, *)
class ViewController: UIViewController,UNUserNotificationCenterDelegate {
override func viewDidLoad() {
super.viewDidLoad()
if #available(iOS 10.0, *) {
//Seeking permission of the user to display app notifications
UNUserNotificationCenter.current().requestAuthorization(options: [.alert,.sound,.badge], completionHandler: {didAllow,Error in })
UNUserNotificationCenter.current().delegate = self
}
}
//To display notifications when app is running inforeground
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
completionHandler([.alert, .sound, .badge])
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
@IBAction func buttonPressed(_ sender: UIButton) {
if #available(iOS 10.0, *) {
//Setting content of the notification
let content = UNMutableNotificationContent()
content.title = "hello"
content.body = "notification pooped out"
content.badge = 1
//Setting time for notification trigger
let date = Date(timeIntervalSinceNow: 10)
var dateCompenents = Calendar.current.dateComponents([.year, .month, .day, .hour, .minute, .second], from: date)
let trigger = UNCalendarNotificationTrigger(dateMatching: dateCompenents, repeats: false)
//Adding Request
let request = UNNotificationRequest(identifier: "timerdone", content: content, trigger: trigger)
UNUserNotificationCenter.current().add(request, withCompletionHandler: nil)
}
}
}
IOS 12 :- Group notification
set threadIdentifier
UNMutableNotificationContent
to create group notification
create local notification group
let content = UNMutableNotificationContent()
content.title = "Group Notifications"
content.body = "Body of notification"
content.threadIdentifier = "group-identifire"
create remote notification group need to pass thread-id
in payload
{
"aps" : {
"alert" : {
"title" : "Group Notifications",
"body" : "Body of notification"
}
"thread-id" : "group-identifire"
}
}
IOS 11 :- You can also use following code for iOS 11. No any kind of changes requires in push and local notification
Creating A Notification Request
import UserNotifications
if #available(iOS 10.0, *) {
//iOS 10.0 and greater
UNUserNotificationCenter.current().delegate = self
UNUserNotificationCenter.current().requestAuthorization(options: [.badge, .sound, .alert], completionHandler: { granted, error in
DispatchQueue.main.async {
if granted {
UIApplication.shared.registerForRemoteNotifications()
}
else {
//Do stuff if unsuccessful...
}
}
})
}
else {
//iOS 9
let type: UIUserNotificationType = [UIUserNotificationType.badge, UIUserNotificationType.alert, UIUserNotificationType.sound]
let setting = UIUserNotificationSettings(types: type, categories: nil)
UIApplication.shared.registerUserNotificationSettings(setting)
UIApplication.shared.registerForRemoteNotifications()
}
Schedule Local Notification
if #available(iOS 10.0, *) {
//iOS 10 or above version
let center = UNUserNotificationCenter.current()
let content = UNMutableNotificationContent()
content.title = "Late wake up call"
content.body = "The early bird catches the worm, but the second mouse gets the cheese."
content.categoryIdentifier = "alarm"
content.userInfo = ["customData": "fizzbuzz"]
content.sound = UNNotificationSound.default()
var dateComponents = DateComponents()
dateComponents.hour = 15
dateComponents.minute = 49
let trigger = UNCalendarNotificationTrigger(dateMatching: dateComponents, repeats: true)
let request = UNNotificationRequest(identifier: UUID().uuidString, content: content, trigger: trigger)
center.add(request)
} else {
// ios 9
let notification = UILocalNotification()
notification.fireDate = NSDate(timeIntervalSinceNow: 5) as Date
notification.alertBody = "Hey you! Yeah you! Swipe to unlock!"
notification.alertAction = "be awesome!"
notification.soundName = UILocalNotificationDefaultSoundName
UIApplication.shared.scheduleLocalNotification(notification)
}
UIApplicationDelegate
func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
let tokenParts = deviceToken.map { data -> String in
return String(format: "%02.2hhx", data)
}
let token = tokenParts.joined()
print(token)
}
func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
}
UNUserNotificationCenterDelegate
Only available in ios 10 and above version
The method will be called on the delegate only if the application is in the foreground
You can present default banner with helping of following method
@available(iOS 10.0, *)
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
completionHandler([.badge,.alert,.sound])
}
The method will be called on the delegate when the user responded to the notification by opening the application, dismissing the notification or choosing a UNNotificationAction
@available(iOS 10.0, *)
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
}
