All steps in the guide worked well, except for one manual change, without which I was getting a runtime error:

In didFinishLaunchingWithOptions of AGAppDelegate.m, I had to manually change the line:

from:	self.viewController = [[AGViewController alloc] initWithNibName:@"AGViewController" bundle:nil];

to:     self.viewController = [[AGViewController alloc] initWithStyle:UITableViewStylePlain];
