IOS SDK that allows the user to draw on the screen and save as an image?

Question

Are there any iOS libraries that provide a custom control where users can draw on the screen and can it be exported as an image file?

Answer 1

Below are some open source projects I found on Github.

• Painter
• Paint-app
• Cloud Finger Paint Client

In terms of libraries or frameworks, here is one of CocoaControls (which, by the way, has a whole collection of Cocoa stuff for OSX and iPhone)

• Smooth line appearance

You can include GLPaint code that Apple provides or uses some code in QuartzDemo Demo application. You can create a simple application using touch methods and UIBezierPaths in a view.
