A library to create gradient border button

How to draw a gradient border button?

My Problem

Last week, my partner showed me his design for our application. Everything is great, easily implemented with some custom controls. But wait, something is not in my knowledge.

A button with gradient border. Never try it before. Up to now, I just created gradient background views 2 times in previous projects. Googled and found some good results.

# delete local tag '12345'
git tag -d 12345
# delete remote tag '12345' (eg, GitHub version too)
git push origin :refs/tags/12345
# alternative approach
git push --delete origin tagName
git tag -d tagName
