Those iOS codes that possibly you find on http://ionicons.com/ are incorrect. The ios part should be changed to ios7 in order for them to show up. The Android ones should be correct though.
@siddharta I understand its text within an icon from Ionic’s Github repository. How does text inside an image work?
However, when you try to do text in ionicons (I tried it for my project), the icon appears very small and words do not populate. The CSS files are tough to understand.
How did you manage to get the repo working on your local? When I run it, it says no Grunt files to run…
