iOS Drawing

Covers iOS 7 and Xcode 5

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.

In this guide, Erica Sadun, bestselling author of The Core iOS 6 Developer’s Cookbook and The Advanced iOS 6 Developer’s Cookbook, helps readers explore iOS drawing through an abundance of examples alongside plenty of explanations and tips. This short work provides the basic how-to developers need to get started. You will learn about these specific topics:

  • The basic concepts of Quartz (Core Graphics) and UIKit drawing
  • The coordinate system, paths, masking, and clipping
  • Text drawing
  • Transparency and alpha channels, drawing modes, blending, colors, and spaces
  • Transforms and geometry
  • Patterns, shadows, and gradients
  • Bitmaps and pixels
