Is Quartz 2D in iOS the same as in Mac OS X?
===

Is Quartz programming consistent between iOS and OS X? I'm looking for a good book on Quartz and came across [one][1] for Mac OS X but am only building for iOS. Since some APIs are different, such as OpenGL, I'm wondering if the same applies to Quartz?
