Now I am creating an application that works like \'iAnnotate PDF\' Till now I have completed reading and displaying pdf pages in UIView. Even I am sucessful i
Maybe this idea can work in iPhone I think there is no directly way we can edit a PDF but what we can do we can produce such functionality that iAnnotate app have i.e. drawing line and text and then just save the PDF as a picture page by page in which you will include the edited page too and then you will create the PDF again by images then I think so you will get the edited PDF.
