Ionic Tabs not showing with Tinder cards directive

Hi,
I am newbie to both Ionic framework and AngularJS. I am working with Tinder-Style Swipe Cards, I can see the cards working well but ,

  1. I cant see default tabs that were created with app. I haven’t changed default tabs controller, routes and views. Just add new new template for cards, controller and respective default route.
  2. I want to use custom brand tab icons for my app, instead of default ionicons, How can I do that?
  3. Also I want to add a background Image which will be available for all the screens.

Can you please help me solve these issues or at least help me find proper resources?

Could you please provide a codepen or demo of your issue
