I finally figure this out and will answer my own question. TWTRNotificationConstants.h posts notification to the NSNotificationCenter. When you look in TWTRNotificationConstants.h it tells you the name of each notification. You can then set up an observer. For example, the observer below now lives in my FirstViewController.m file.
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(likeTweetNotification:) name:@“TWTRDidLikeTweetNotification” object:nil];
You then need to create a method with your selector name to do something when the notification is received. In this example, it might look like this:
- (void)likeTweetNotification:(NSNotification *) notification {
// do something
}
Also note that the notification carries some extra information in the userinfo dictionary that can be a part of NSNotifications. It seems to be the tweet’s @username and text. You could access that dictionary by adding some lines to the above method like so:
- (void)likeTweetNotification:(NSNotification *) notification {
NSDictionary *tweetInfoDict = [notification userInfo];
NSLog(@“Dictionary: %@”, [tweetInfoDict description]);
}
