IFXPDFFactory 0.1.0 Alpha version now available

November 15th, 2013

First version of IFXPDFFactory for iOS is now available. It's an alpha version which means it has bugs and only the basic features are implemented but it lets you feel the API and test the concepts shown in the articles published so far.

There are 14 samples included in the samples browser application to show the features implemented so far. There is no Apple style documentation yet, but it will come.

Feel free to download the framework and take it for a test drive. Any questions you might have can be posted here as comments or sent by email to me.
