How to Set an Alarm in iOS

iOS how to set Alarm and schedule work/notifications

You many have to schedule local notification which is now available in UNUserNotificationCenter.

So,

1. For Scheduling a Notification Locally from Your App, follow this doc.
2. For Handling Notifications and Notification-Related Actions, follow this doc.

To Handle Notifications in your AppDelegate or where you want to handle UNUserNotificationCenter delegate method, add below code:

class AppDelegate:NSObject, UIApplicationDelegate, UNUserNotificationCenterDelegate{

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {

    let center = UNUserNotificationCenter.current()
    center.delegate = self // Don't forgot to set delegate

    //To get permissions from user:
    let options: UNAuthorizationOptions = [.alert, .sound, .badge];
    center.requestAuthorization(options: options) {
        (granted, error) in
        if !granted {
            print("Something went wrong")
        }
    }

    return true
}
}

How to set Alarm in ios?

You can't set alarm like default clock application. All you can do is use LocalNotification and add sound to it (30 seconds max). And sound won't play if the phone in silent mode.

How To Create Alarm Notification Swift iOS?

Due to Apple's limitation, app dev can only play notification tone up to 30 seconds. It will play default notification tone if your tone is longer than 30 seconds.

If your notification tone is gone after 5 seconds, try to set your notification presentation options to list, badge and sound.
Once there's no banner for notification, your 30seconds tone will play till the end.

Unfortunately there's no legal way or any workaround to have notification ring continuously such as alarm clock. Hope I was wrong though.

How to set an Alarm in iOS?

1. First on your xib, (or code) set the date picker mode: Time (Default is date & time)

2. The system assumes that the firedate is the current date, and the time is the time the user have chosen. This is not a problem because you set a repeat interval so it will work. I have tested it.

   UILocalNotification *localNotif = [[UILocalNotification alloc] init];
   [localNotif setFireDate:datePicker.date];
   [localNotif setRepeatInterval:NSDayCalendarUnit];
   [[UIApplication sharedApplication] scheduleLocalNotification:localNotif];
   

PS: It would be a good idea to set the seconds to 0 using NSDateComponents class so as to set the alarm to ring at the first second of the minute you want. You can check the:

Local notifications in iOS.

tutorial you posted on how to do this.

Is it possible to build an alarm clock such as the built in app from Apple?

Unfortunately this is unavailable for developers. You can check all of alarm clock apps in AppStore, all of them are using the standard local notifications. Which will fire once and that's all. You can of course set your custom sound and change couple of options, but it will never work like one build in Clock app inside iPhone.

You can read more about local notifications in Apple documentation: https://developer.apple.com/reference/usernotifications/unnotificationrequest

How to create alarm app in flutter for ios

i found a work around for the problem using flutter local notification package , you can schedule notification in the future and it would work in foreground, background and when app terminated so covering all cases and work perfectly in my scenario. if you need to do something like alarm or reminder for IOS it will do the job for you.

var scheduledNotificationDateTime =
    DateTime.now().add(Duration(seconds: 5));
var androidPlatformChannelSpecifics =
    AndroidNotificationDetails('your other channel id',
        'your other channel name', 'your other channel description');
var iOSPlatformChannelSpecifics =
    IOSNotificationDetails();
NotificationDetails platformChannelSpecifics = NotificationDetails(
    androidPlatformChannelSpecifics, iOSPlatformChannelSpecifics);
await flutterLocalNotificationsPlugin.schedule(
    0,
    'scheduled title',
    'scheduled body',
    scheduledNotificationDateTime,
    platformChannelSpecifics);

Is there a way to get iOS System alarm notifications?

Unfortunately not. You have to stay within the confines of your app. The iOS Clock app has special privileges because...well, it's made by Apple.

Is the notification not enough? I would think that would alert the user adequately.
