Calculator.pdf

概要

At PSPDFKit, we have Experimental Fridays, which are days when everyone in the company works on special interest projects or things that are different than the day-to-day work. On one of those days, I experimented with creating a calculator inside a PDF. The iPad, for example, doesn’t provide a stock calculator app, so could we have one inside PSPDFKit, which works beautifully on iPad?
