I am a newbie in iPhone development. I am planning to do a PDF application for iPhone. The functionality is:
User will type their input in a text field (which is going to be the content of the PDF file).
I have to modify the PDF file through code while saving (paragraphs, tables, bullets etc).
User can save it in their own name.
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?
I've used this reference: https://developer.apple.com/library/ios/#documentation/GraphicsImaging/Conceptual/drawingwithquartz2d/dq_pdf/dq_pdf.html
It contains theoretical explanations and source code examples
Please use the below link to download sample apps for PDF Reader/Viewer in iOS

Also please look at detail about pdf creation, manipulation etc in below links

If you were doing a Phonegap app I'd say got for jsPDF, which would enable you to create (basic) PDF files in Javascript. I don't do Obj-C, but a quick look on SO provides good links.

We want to share PDF or other documents using JSQMessanger. Because we have used JSQMessanger for chating in our App.
You should expand JSQ functionalities for the PDF source
Look at how the example app does media items i.e. Video or images. It will be similar to this and then you just need to adapt it so that it can handle the PDF payload. Definitely a great thing to add to the library.
I have an app in which some PDF files are downloaded and my problem is simple : I need to have the ability to sign them (drawing signature on screen) anywhere and save it to PDF format without modifying the structure of my PDF file.
The new feature in iOS 9 : Markup in the mail app does EXACTLY what I need. However, I don't want to use Mail in my app...
I've found on the web some ways to Generate PDF content, but very few examples and nothing that could help me with my problem.
Opening a PDF, turning it into NSData, create a context to render the signature then render both the PDF and the layered signature to finally save the NSData to PDF seems to be a pain, isn't it ?
Can someone help me either
Use markup features without using mail app or use it as transparent as possible for the user
Or, any reliable tutorial to draw signature over PDF without using a third-party app ?
Thank you,
Quick question, that I haven't found a solid answer yet.
Is it possible to generate a PDF in iOS that includes layers, which can then be removed/separated in Photoshop?
What I'm trying to achieve is take a picture with the camera of the phone, then place text over it, submit it as pdf to a customer and then have the customer read the text and remove it.
I can do everything except the layering of the pdf and I have found some hints that this isn't possible to do with the standard iOS library, but I wanted to know if anyone has come across this before.
Thank you.
The standard iOS API for creating PDF files cannot create layers (optional content) in a PDF page.
This library IFXPDFFactory seems to be able to generate PDF files with layers.
PoDoFo and libHaru can also be used to generate PDF files on iOS but I do not know if they support layers.
Hi i'm wanting to create a webpage in which i can pass a url to a document and it previews it. the idea behind this is so i can create a responsive web view for android so i can preview documents from with an app i have basic knowledge of php and html but if some one could point me in the right direction? i have had a look around but can't find anything that basic i don't need to edit the documents just view them. Does anyone know how to do this?
ps: the docs i want to preview are .xl .xls .doc .docx .pdf .ppt etc
Here is what looks to be a decent open source option.

One option would be to convert the documents to .pdf first using OpenOffice and then preview them using pdf.js
I am looking to be able to open a pdf file (done) and then be able to use the touch screen to sign the pdf and then save it with the modification. From what i have read this is no easy task, and i have no idea where to begin. Any of you know any tutorials or frameworks that will help me with this ?
Also if possible being able to modify fields of a pdf file, on the desktop the pdf can have fields you can click on then type in to fill out the form, without the need to ever print. If this is possible as well that would be perfect.
Thanks.
Maybe libHaru (http://libharu.org/wiki/Main_Page) does what you want, it's worth a try.
Does your starting point have to be a PDF? steipete's suggestion of using a system to create the PDF would work if your app workflow could create the PDF (sans signature) and display it, the user "signs" it in your app, and you create the PDF again this time with the signature embedded. It depends on whether this flow is an option for your app. Often it seems easier if you treat PDF as a final document and produce the PDF in it's final form each time (final meaning that you're not going to try modifying it).
