Changes In iOS Foundations Deep Dive: Notifications?

I think I'v noticed a few changes to this using Xcode 5 / iOS 7.

  • When creating the new project, I do not see a way to not use the StoryBoard.
  • I don't think it's necessary to add the notification code for the 2nd view controller in the AppDelegate. I couldn't figure out the AppDelegate code, so I added this line
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(textFieldChanged:) name:@"textFieldChanged" object:nil];

in my SecondViewController implementation, and the app works.

Am I missing something, or are my observations correct?

Thanks, Rycardo

Your observations are right. With Xcode 5, Storyboards are the default experience and there is no other option. Notification observers can be added anywhere, they don't have to be in the AppDelegate. As long as you add the observer within the view controller that needs it then you are fine.
