Thanks for this tutorial! I’ve been struggling with fonts for a while now. Turns out my problem was that I was trying to select a font that couldn’t be selected. (”Arial”)

Anyways, is there a list of which fonts are available and what’s the strings to use to refer to them?

Is there any way to have the source code of this article? I am a beginner and I think something is missing on my app. The drawRect method is never executed.

Thanks for the examples, they’ve helped me a lot.

However, the color setting calls (like CGContextSetRGBStrokeColor) are a little misleading in the examples. With values like 0 and 255 it would appear that they are single byte values when they are actually supposed to be floats in the range of 0 to 1. Anything greater than 1 is treated as full intensity.

I’m trying to figure out how to fill text with a gradient (like the numbers in the Calendar app have a subtle gradient). I haven’t found any examples of how to do this. Could subclassing UILabel accomplish this? How could I do this with an existing Label built in Interface Builder?

I’m betting you already know how to do this. Thanks.
