As the ultimate goal would be to compile it on Windows and OS X as well, I'm inclined to use C++ (and only use ObjC for the stuff that I have to: App Delegate etc.), but I have zer...

I started a new project with XCode and I have set up the subversion repository. For some weird reason, in this project the "Add to repository" menu items are not working, both in the main menu and by right clicking a file.

Hi I have a bunch of NSStrings in a NSMutableArray. I have added them to the array and now I want to loop through the array, getting each object in it (the strings) and set them to a common value @"No Lessons".

Hi all, I have a UITableView and its data gets refreshed from a server connection. For the UITableViewcell, I have layout some labels across the row.
