objective c - Add accessibility to pdf created with Quartz2d in iOS app -

-

I am using Quartz 2D to create a PDF file in an iOS app based on the Wenderlich tutorial. However, when the PDF user is displayed (using QLPreview), the voice over reads PDF in a very intuitive order, whether there is a way to modify the PDF when it reads voice over data designed to change the order. , And to add meta-data to images so that they are read properly? Thanks for any advice or help for this.

The simple answer is: This is not possible. Quartz is just a drawing engine and does not have a dedicated PDF library.
You should try writing the text on the page you want to read, it can help. I think (I'm not sure) is visible in the content of the page through the voice over text, when access Capacity is not present.
