Is it possible to graph a polar function with UIBezierPath? More than just circles, I'm talking about cardioids, limacons, lemniscates, etc. Basically I have a single UIView, and want to draw the shape in the view.
There are no built in methods for shapes like that, but you can always approximate them with a series of very short straight lines. I've had reason to approximate a circle this way, and a circle with ~100 straight lines looks identical to a circle drawn with ovalInRect. It was easiest when doing this, to create the points in polar coordinates first, then convert those in a loop to rectangular coordinates before passing the points array to a method where I add the lines to a bezier path.
