Call Alert Ionic

Ionic Framework ionic-v3
1

My method file1.ts

  create(cad) {
    this.service.postData(cad.value)
                .subscribe((data) => {
                  this.callAlert(data);
                });
  }

I want to call alert method

callAlert(data) {
    if(data) {
        let alert = this.alertCtrl.create({
          title: 'Success!',
          subTitle: 'Successfuly',
          buttons: ['Ok']
        });
        alert.present();
    } else {
      this.navCtrl.push(Login).catch( err => {
        let alert = this.alertCtrl.create({
          title: 'Ops!',
          subTitle: 'Houve algo de errado',
          buttons: ['Ok']
        });
        alert.present();
      });
    }

and redirect to any page (Login Page) -> example
But doesn’t work please

No errors? I assume these 2 pieces of code are in the same class?

I would something simple see you:

registe(data) {
    if(data){
         //call alert method and redirect to another page ???
    }
}

showAlert() {
    this.alert = this.alertCtrl.create({
      title: 'Titulo aqui',
      subTitle: 'Subtitulo aqui para teste vamos ver no que vai dar',
      buttons: ['Ok']
    });
    this.alert.present();
  }

only that

Assuming I understand correctly, here’s my 2 examples

Alert and redirect

registe(data) {
	if(data){
		this.showAlert();
		this.navCtrl.push(PageComponent);
		// or
		this.navCtrl.setRoot(PageComponent);
	}
}

showAlert() {
	this.alert = this.alertCtrl.create({
		title: 'Titulo aqui',
		subTitle: 'Subtitulo aqui para teste vamos ver no que vai dar',
		buttons: ['Ok']
	});
	this.alert.present();
}

Alert then redirect

registe(data) {
	if(data){
		this.showAlert().then(() => {
			this.navCtrl.push(PageComponent);
			// or
			this.navCtrl.setRoot(PageComponent);
		});
	}
}

showAlert() {
	return new Promise(resolve => {
		this.alert = this.alertCtrl.create({
			title: 'Titulo aqui',
			subTitle: 'Subtitulo aqui para teste vamos ver no que vai dar',
			buttons: ['Ok']
		});
		this.alert.present();
		this.alert.onWillDismiss(() => resolve);
	});
}

Someting along these lines
