Must you call CGContextClosePath after CGContextBeginPath?

If my path ends where it starts, then is it OK to omit the call to CGContextClosePath?

Not necessarily, only if you want to close the subpath. According to iOS Developer Library : Quartz 2D Programming Guide:

Closing a Subpath

To close the current subpath, your application should call CGContextClosePath. This function adds a line segment from the current point to the starting point of the subpath and closes the subpath. Lines, arcs, and curves that end at the starting point of a subpath do not actually close the subpath. You must explicitly call CGContextClosePath to close a subpath.
