In this tutorial I’m going to introduce you to the techniques used to draw 3D stuff with Core Animation. The good news are Core Animation can help us achieve some 3D goodness without using OpenGL directly.

In this two parts iOS tutorial I’ll show you a way to connect Core Graphics, Core Animation and Touch event management. The result of this experiment is a circle filled with a red gradient which appears smoothly when the user touches the screen, following his pan actions.

Prior to iOS 6, accessing the calendar didn’t require any permission. We just had to create an event store and then we were able to add events through it. With iOS6 the story is slightly different: to create a new event we ask the user for the permission to access his calendar. Thanks to the new function...

In this simple tip I will show you how to open the main window of your application using the Dockbar icon. Your users probably expect the main window of your application to become visible through a click over its Dockbar icon, but, unless you’ve managed this behavior, when they click the icon nothing happens. Since we don’t...
