iOS drawing
Apple lavished iOS with a rich and evolving library of resolution-independent 2D drawing utilities. Its APIs include powerful features such as transparency, path-based drawing, anti-aliasing, and more. Harness these low-level, lightweight drawing routines in your apps to build images, to create PDFs, to display views, and to print.
