For a long time I’ve wanted more convenience methods for UIColor. The set Apple provides is a nice starting point but I often find myself wanting more. In particular, the Mac color picker has a crayon box color picker with common colors. Sadly, there are no convenience methods for these colors. Since I use them so frequently, I decided to put them all in a category. This was tedious work since I had to do them one-by-one by hand.
After getting these 48 convenience methods I figured why stop there. I moved on to the HTML colors. At the time I didn’t realize how many standard HTML colors exist (147). After seeing that number I almost threw out the idea, but I remembered that @alesplin taught how to use Vim macros in the November BYU CocoaHeads meeting. Using a list of HTML colors and their associated hex values, I had all 147 HTML color convenience methods finished within minutes. Vim may be an old, crusty text editor, but its macro editing power is unmatched by modern IDEs.
If you want a copy of my UIColor category, you can find it in my RBCategories repo on Github.
