I created the pdf that contains multiple QR codes, Now I want to decode all the QR codes which are present in the PDF file without scanning them, I searched about it and didn't get anything.
Thanks in advance
I'm creating the QR codes using rqrcode gem.

I am trying to generate a qr code of a google sheets file that ends with "edit#gid=1473689815". This last part of the URL is the name of a specific sheet in the file. So the problem is that when I scann the qr code with my iPhone (without a spefic qrcode leser app) the code brings me to the first sheet of the file. Do you maybe know if this part of the URL is making some trouble at the moment of the qrcodegeneration? What else should I try?
And no matter which app I use (neither generating the qrcode on google sheets itself) the qr code brings me ALWAYS to the first sheet of the file.
Thanks for your help!
Try to encode the url before generating the qrcode with
encodeURI(url)
encodeURI
I am creating app where i need to load the pdf file from document directory and need to highlight text manually by user.
Also we need to export the updated pdf file and upload it to the server.
Is there any way to manage the same using pdfkit ?
Please share the sample code if available.
We are using the library as a reference is listed below
https://github.com/uxmstudio/UXMPDFKit
This library is using the same concept as we need but exporting the pdf is the main task we need to achieve.
In simple word we can say that user can highlight some text from the displayed pdf text and upload it to the server.
I am reading a PDF file stored locally (using nsbundle) and converting it to text.
But when I am trying to read the PDF from http i.e. URL scheme and give the path to my PDF to text converter it returns nil.
Any solutions would be appreciated.
My basic question is how to read a PDF file from a URL path?
on that way there are many restriction to convert PDF file to plain text.If you want to display PDF on app then use PDF Reader Core
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,
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

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.
