How do I set a particular UITextField on my firstViewController to focus when my sec开发者_StackOverflowondViewController pops from the navigationController?

Write [TexfieldName becomeFirstResponder]; in ViewdidLoad in secondViewController.

This will focus to particular textField and show keyboard.

If you don't want to use viewWillAppear:, you could make use of the UINavigationControllerDelegate method – navigationController:willShowViewController:animated: and make invoke your method that way instead.

Just make sure some class is the delegate of you navigation controller, and get it to call a method in firstViewController invoking becomeFirstResponder.

EDIT: Link to the Apple documentation on UINavigationControllerDelegate.
