It may be a question in advance but I wonder what to use instead of UILocalNotification
in iOS 10. I am working on an app which has deployment target iOS 8 so will it be ok to use UILocalNotification
?
As you are already aware, you can schedule maximum of 64 notifications per app. If you add more than that, the system will keep the soonest firing 64 notifications and will discard the other.
With local notifications, your app configures the notification details locally and passes those details to the system, which then handles the delivery of the notification when your app is not in the foreground. Local notifications are supported on iOS, tvOS, and watchOS.
Overview. Create a UNMutableNotificationContent object when you want to specify the payload for a local notification. Specifically, use this object to specify the title and message for an alert, the sound to play, or the value to assign to your app's badge.
Yes, you can use UILocalNotification
, old APIs also works fine with iOS 10, but we had better use the APIs in the User Notifications framework instead. There are also some new features, you can only use with iOS 10 User Notifications framework.
This also happens to Remote Notification, for more information: Here.
New Features:
It is really easy for us to convert UILocalNotification
APIs to iOS 10 User Notifications framework APIs, they are really similar.
I wrote a demo here to show how to use new and old APIs at the same time: iOS 10 Adaptation Tips .
For example,
With Swift implementation:
import UserNotifications
/// Notification become independent from UIKit import UserNotifications
request authorization for localNotification
let center = UNUserNotificationCenter.current() center.requestAuthorization(options: [.alert, .sound]) { (granted, error) in // Enable or disable features based on authorization. }
schedule localNotification
update application icon badge number
@IBAction func triggerNotification(){ let content = UNMutableNotificationContent() content.title = NSString.localizedUserNotificationString(forKey: "Elon said:", arguments: nil) content.body = NSString.localizedUserNotificationString(forKey: "Hello Tom!Get up, let's play with Jerry!", arguments: nil) content.sound = UNNotificationSound.default() content.badge = UIApplication.shared().applicationIconBadgeNumber + 1; content.categoryIdentifier = "com.elonchan.localNotification" // Deliver the notification in 60 seconds. let trigger = UNTimeIntervalNotificationTrigger.init(timeInterval: 60.0, repeats: true) let request = UNNotificationRequest.init(identifier: "FiveSecond", content: content, trigger: trigger) // Schedule the notification. let center = UNUserNotificationCenter.current() center.add(request) } @IBAction func stopNotification(_ sender: AnyObject) { let center = UNUserNotificationCenter.current() center.removeAllPendingNotificationRequests() // or you can remove specifical notification: // center.removePendingNotificationRequests(withIdentifiers: ["FiveSecond"]) }
Objective-C implementation:
import UserNotifications
// Notifications are independent from UIKit #import <UserNotifications/UserNotifications.h>
request authorization for localNotification
UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter]; [center requestAuthorizationWithOptions:(UNAuthorizationOptionBadge | UNAuthorizationOptionSound | UNAuthorizationOptionAlert) completionHandler:^(BOOL granted, NSError * _Nullable error) { if (!error) { NSLog(@"request authorization succeeded!"); [self showAlert]; } }];
schedule localNotification
update application icon badge number
UNMutableNotificationContent *content = [[UNMutableNotificationContent alloc] init]; content.title = [NSString localizedUserNotificationStringForKey:@"Elon said:" arguments:nil]; content.body = [NSString localizedUserNotificationStringForKey:@"Hello Tom!Get up, let's play with Jerry!" arguments:nil]; content.sound = [UNNotificationSound defaultSound]; // 4. update application icon badge number content.badge = [NSNumber numberWithInteger:([UIApplication sharedApplication].applicationIconBadgeNumber + 1)]; // Deliver the notification in five seconds. UNTimeIntervalNotificationTrigger *trigger = [UNTimeIntervalNotificationTrigger triggerWithTimeInterval:5.f repeats:NO]; UNNotificationRequest *request = [UNNotificationRequest requestWithIdentifier:@"FiveSecond" content:content trigger:trigger]; /// 3. schedule localNotification UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter]; [center addNotificationRequest:request withCompletionHandler:^(NSError * _Nullable error) { if (!error) { NSLog(@"add NotificationRequest succeeded!"); } }];
Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'time interval must be at least 60 if repeating'
let trigger = UNTimeIntervalNotificationTrigger.init(timeInterval: 60, repeats: true)
Apple have done it again, the correct implementation is: AppDelegate.swift
if #available(iOS 10.0, *) { let center = UNUserNotificationCenter.currentNotificationCenter() center.requestAuthorizationWithOptions([.Alert, .Sound]) { (granted, error) in // Enable or disable features based on authorization. } } else { // Fallback on earlier versions }
and don't forget to add
import UserNotifications
