exit a view on iPhone

Question

how do i programmatically exit a view in an iPhone app

Answer 1

This is a pretty vague question… I can interpret it a few ways:

1) How do I dismiss a view controller manually in a Navigation Controller

[self.navigationController popViewControllerAnimated:YES];

2) How do I dismiss a modal view controller manually in a Navigation Controller

[self.navigationController dismissModalViewControllerAnimated:YES];

3) Remove a view from the view hierarchy

[theView removeFromSuperview];

4) How do I programmatically exit the app

exit(0);
