iOS Activity Overlay

I was recently working on an iOS project and was implementing a login view. As usual, the user enters their credentials, the credentials are sent to a server for verification and, if successful, the user is allowed into the app. The problem I ran into is that the asynchronous account validation leaves the user on […]

Interop Objective-C Objects In C Using ARC

Introduction Using C functions from Objective-C is very easy but going the other way isn’t so easy.

Preparing Music for Manual Copying Through iTunes

Kevin Hendricks and Doug Massay have been working on Sigil with me for months now. I’m leaving it in their very capable hands. To accommodate this transition I’ve created […]
