How to get the active tab index in Ionic 2?

Question

Is there any way to get the active tab index in Ionic 2? I have searched, in Ionic 1 there is $ionicTabsDelegate.

Answer 1

Pass the event object to your method:

<ion-tabs (ionChange)="tabSelected($event)">

The event object is actually the selected Tab:

tabSelected(tab: Tab) {
  console.log(tab.index);
}

Answer 2

Your navController should link to the nested Tab which has a property 'index'.

console.log((<Tab>this.navCtrl).index);

I think this is a little hacky so I'm happy to see other answers. But for the moment you could try that :)
