Moving Core Data to the Singleton

      1 Comment on Moving Core Data to the Singleton

[UPDATE:] You might like to read Revisiting the Singleton to see how my opinion has changed on this. Now we’ve established the principle of using a Singleton as our main app coordinator, it would make more sense to move the Core Data functions there.  If you choose to add Core Data when generating from an XCode template, these function are… Read more »

Application Wide Variables and Helpers: The Singleton

      1 Comment on Application Wide Variables and Helpers: The Singleton

One dilema when writing an app is where to put variables that contain the data for the application.  Traditional global variables are not a good place, and it becomes nigh on impossible to keep track of where those variables are being access from in the code, and in multi-threaded apps it would also be difficult to coordinate atomic access.

I’m a long time developer.  Now approaching 42 years of age, I’ve been writing code since I was 18.  Perhaps earlier if you can count crufty attempts to write my own version of Tron on the Commodore Vic 20.  But less said about that the better! I started out using a 4GL called ‘TAS’ which was a fine little language… Read more »

A Newbies Journey in Developing Apps for the iPhone

      No Comments on A Newbies Journey in Developing Apps for the iPhone

This is the start of a journey.  I’m about to venture into the world of iPhone application development.  I have no intention of making a million (although that would be nice), but I do want the apps that I create to be commercial. I’ve waited longer than most to dip my tow, partly just because life was getting in the… Read more »
