Some notes:

"iPhoneOSNote: If you want to create a PDF graphics context in an iPhone application, make sure you also read “Drawing to a Graphics Context in iPhone OS” (page 27)."

"You can write any content to a PDF that’s appropriate for your application—images, text, path drawing—and you can add links and encryption. For more information see “PDF Document Creation, Viewing, and Transforming” (page 177)."

As an example of creating a PDF from the contents of a CALayer, you can refer to the -dataForPDFRepresentationOfLayer method within the CPLayer class in the Core Plot framework. You can do something similar to extract the content from a CALayer-backed UIView, although we had to subclass CALayer in order to get vector elements to render to a PDF properly.

Use this library to generate pdf file by programmatically.
