Theres a great open-source api for creating PDF files. You can add text, images, and headlines to a PDF, and then send the PDF or save it to a file. Api is at http://code.google.com/p/pdf-api-iphonesdk/wiki/PDFAPI If you have any questions about this, the support is great, just contact maor.kern@mobice.org

You can use UIKit to generate pdf. It is very simple. You just need to run the PDF context and write it to it:
