What is the difference between self.navigationController and delegate.navigationController

Question

I can use

MyFirstAppDelegate *delegate = (MyFirstAppDelegate *)[[UIApplication sharedApplication] delegate];
[delegate.navigationController popViewControllerAnimated:YES];

or

[self.navigationController popViewControllerAnimated:YES];

So what is the difference between both?

Please answer me...

Thanks in advance.
