Rounded UIView using CALayers - only some corners - How?
...us values in the code. The code for all corners is there, so use that as a starting point and delete the parts that create corners you don't need. Note that you can make rectangles with 2 or 3 rounded corners too if you want.

...l shapefile : bl.ocks.org/4485308 and bl.ocks.org/4348435.
