I have been working with Fotran for Windows for years and have integrated it with Visual Studio with very little problem I program in either Microsoft Access of VB.net to call my fortran program.
I now have a customer base that is wanting me to do this for their Ipads. I make custom software in which I integrate my fortran libraries into the given development environment. Is this possible to do with IOS applications and if so, how do I call the fortran libraries that I have created. I realize that I will have to make some changes to my already working fortran programs, but I don't want to lose the work that I have already done.
