Closing a view displayed via a modal segue

I'm manually invoking a segue (set as modal) in order to display a login form in Xcode 4.2 using Storyboards with the following line of code:

[self performSegueWithIdentifier:@"LoginSegue" sender:nil];

I'm probably missing something really simple, however I can't find a way to programmatically close the login view and return to the previous view.

The view is part of a navigation view controller, so setting the segue type to "push" allows me to use the back button to send me back to my previous screen, but in "modal" mode, I'm not entirely sure how to achieve this (after button press, for example)

Any help would be much appreciated.

If your deployment target is iOS 5.0 or later, use this message:

[self dismissViewControllerAnimated:YES completion:nil];

Or in Swift:

self.dismissViewControllerAnimated(true, completion: nil)

If your deployment target is older, use this (deprecated) message:

[self dismissModalViewControllerAnimated:YES];

The following should work fine...

[self dismissModalViewControllerAnimated:YES];

I do exactly this with a login page in my latest tutorial here, with no issues.

[self dismissViewControllerAnimated:YES completion:nil]; is a new way in IOS5

The following code works in swift 3:

 self.dismiss(animated: true, completion: nil)
