Wrap up

I could easily have written twice as much about Core Graphics, because it's capable of some extraordinary effects. Clipping paths, gradients, blend modes and more are just a few lines of code away, so there really is no excuse not to give them a try! And if you don't give it a try yourself, don't worry: we'll be drawing with Core Graphics in project 29, so you can't avoid it.

This project has given you a sandbox where you can play around with various Core Graphics techniques easily, so I would highly encourage you to spend another hour or two tinkering with the code in your project. Use code completion to try new functions, change my values to others to see what happens, and so on. Playing with code like this can help you to discover new functionality, and will also help you remember more later. Have fun!
