<ion-tab [root]=“tab1Root” tabTitle=“aaaa” tabIcon=“calendar”>
<ion-tab [root]=“tab2Root” tabTitle=“ssss” tabIcon=“contacts”>
<ion-tab [root]=“tab3Root” tabTitle=“dddd” tabIcon=“contacts”>

I want use svg image. Is it possible?


You’re likely not going to want to hear this, but now might be a great time to update this app, because what you ask is vastly easier in v4.
