I have installed the plugins like so:

ionic cordova plugin add cordova-plugin-local-notification
npm install --save @ionic-native/local-notifications

Code:

app.component.ts

constructor(){
 this.platform.ready().then(() => {
    timer(60000, 60000).subscribe(val => {//schedule Notification
      const hours = moment().format("H");
      const minutes = moment().format("m");
      if (hours == '10' && minutes == '1') this.scheduleNotification();
        });
    this.localNotificationHandler();
 });
}

scheduleNotification() {
    forEach(this.authenticationProvider.member.projects, (project: Project) => {
      forEach(project.transactions, (transaction: Transaction) => {
        if (transaction.dueOn != null && moment(transaction.dueOn).format('YYYY-MM-DD') == moment().format('YYYY-MM-DD')) {
          const id = random(1, 1000);
          cordova.plugins.notification.local.schedule({
            id: id,
            title: 'Due Today',
            text: `Payment for ${transaction.category.name}: ${transaction.description} of ${Number(transaction.totalPrice).toLocaleString()} is due today.`,
            data: { transaction: transaction, project: project },
            trigger: { every: { hour: 10, minute: 1 } },
          });
        }
      });
    });
  }

  localNotificationHandler() {
    this.localNotifications.on('click', (notification, state) => {
      const data = notification.data;
      const transaction = data.transaction;
      const project = data.project;
      this.goToEditTransaction(transaction, project);
    });
  }

It is working fine on the same day if an app goes to background mode few hours (less than 4 hours) on android device. But it is not working on iOS 11.2 or iPhoneX. On the Android device itself, we cannot trigger the click event. If we clicked the notification It opens the app again with a splash screen and goes to the desired screen (i.e. Edit ) without relevant data. That is useless since we need data for the edit screen.Could you tell me how to solve these issues?

Same sort of issue: https://forum.ionicframework.com/t/ionic-local-notification-trigger-call-back-is-not-working-when-app-is-in-background-for-a-while/114925

Times do not work on the background on IOS. You cannot schedule a notification using a background timer as the moment the app goes in the background, the JavaScript timer stops.

The Xcode simulator does not emulate the real IOS OS and keeps background timers running.

As said before, strip your code back and start with something simple and work your way up to something complicated.

@ddralves @Sampath-Lokuge I am using IONIC 1 and I am having the same problem… I’m trying to generate local notifications in the background. they work on an iphone6 but on an iphone xr nothing happens. I’m testing them in a simulator.
