PDF generation in XCode

Programming for ios: PDF generation in XCode on newest questions tagged ios – Stack Overflow

I am a newbie in iPhone development. I am planning to do a PDF application for iPhone. The functionality is:

1. User will type their input in a text field (which is going to be the content of the PDF file).
2. I have to modify the PDF file through code while saving (paragraphs, tables, bullets etc).
3. User can save it in their own name.
4. User can send the PDF file as attachment of MFMailComposer.

So I have searched and got many links. However I didn’t find any leading details to create and modify a PDF file in iPhone/iPad.

Can anyone please provide me a good reference to do this. Are there any alternatives to do this?
