I need to use customs icons with tabs in ionic 2.

Moreover I need to change the title color and icon, if the tab is selected.

Example:

This is the easiest way I've found, from the forums at https://forum.ionicframework.com/t/anyway-to-custom-the-tabbars-icon-with-my-own-svg-file/46131/36.

In your app.scss file, add the following code:

ion-icon {
    &[class*="custom-"] {
        // Instead of using the font-based icons
        // We're applying SVG masks
        mask-size: contain;
        mask-position: 50% 50%;
        mask-repeat: no-repeat;
        background: currentColor;
        width: 1em;
        height: 1em;
    }
    // custom icons
    &[class*="custom-icon1"] {
        mask-image: url(../assets/img/customicon1.svg);
    }
    &[class*="custom-icon2"] {
        mask-image: url(../assets/img/customicon2.svg);
    }
    &[class*="custom-icon3"] {
        mask-image: url(../assets/img/customicon3.svg);
    }
}

Then in your templates, you can use the following HTML to create the icon:

<ion-icon class="custom-icon1"></ion-icon>

In other questions, people suggest a font based method. This answer though is far less complicated to use, as long as you're not adding hundreds of icons you should be okay. The caveat is that each image is sent as a separate request, where as with the font methods all the images are contained in one file, so it would be a little more efficient.

  • It works when I'm running with `ionic cordova run android -lc` but icon not shwoing on production build. Any solution? – Ankur Jan 21 '19 at 10:29

Check out the tabs component of ionic 2 here.

Refer this for using custom icons and how to display them on tabs.

Also, I think you can change the CSS properties of your title and icon through .animate class.

If not, then Inspect Element from you browser window and find a class which changes when the tab is selected. You can run your project in browser by ionic serve.
