Select a specific tab in Ionic 2

Question

I\'m trying to use the Ionic 2 and I\'m still struggling with most basic tasks, such as select a tab when the app is loading.

I\'ve tried to inject the Tabs

Answer 1

//importing tabs for manipuling our ion-tabs
import {Tabs} from 'ionic-angular';
@Page({
    templateUrl: 'build/pages/page1/page1.html'
})
export class Page1 
{
    //provide Angular with metadata about things it should inject in the constructor
    static get parameters()
    {
        return [[Tabs]];
    }
    //after injecting ,passing an instance of [Tabs] in the page constructor 
    constructor(tab) {
        this.tab = tab;   
    }
    //"onPageWillEnter" function fires every time a page becomes the active      view.
    onPageWillEnter()
    {
        //make the second tab selected From the first tab (within the current Page 'page1')
        // 1 IS the index of the target tab
        this.tab.select(1);
    }
}
