how to show an alert when you start your application ? it works good on click but how to initiate the alert during the start of the app.

2

Wrap your Alert in either

onPageLoaded(){}
onPageWillEnter(){}

or
onPageDidEnter(){}

in yourr start page.

you can always rise the alert on your “first” controller, the easiest way.

.controller('FirstCtrl', function($scope, ) {

alert('Hey you!');

...
...
})

Do not put inside constructor :slight_smile:

constructor(private nav:NavController){
  blah blah
 }

  onPageLoaded(){
     let myAlert=Alert.create({
                            title: 'Example',
                            message: "This is an example",
                            enableBackdropDismiss:false,
                            buttons: ['OK']
                        })
     this.nav.present(myAlert);
  }
