Ole Zorn forked and improved on a nifty method created by Marco Arment
of Instapaper fame. It takes a
UIImage and treats it as a mask to fill it’s
opaque parts with a solid color. Marco uses it to generate arbitrarily colored
icons on the fly. Ole took his original idea and simplified it.
This is also a great example of how gists work. A gist is snippet of code
posted online (publically or privately) similar to Pastie. The killer feature,
though, is that you have a full history of changes to that snippet and can even
fork a snippet keeping the full history of it’s lineage. If you want to see
Marco’s original method before Ole improved it, just click the oldest revision
in the right sidebar.
