I use HTML as the basis of all my Invoices. I can convert HTML to a PDF (for emailing) on Desktop and Web using HTML2PDF (all working in my apps), but I lack this feature for the iOS version of my app.
I am thinking of using a URLConnection on iOS to send the HTML to a WebApp, the WebApp converts the HTML to a PDF, then replies with the PDF. I am sure this will all work, as it is a known quantity.
I cannot think of any other alternative method. Is there a better way, or am I mad?
