Ch. 6 - pg. 163

This section of the book discuss 2 techniques for dismissing the Keyboard when entering text.
The 1st. technique involves clicking the "Return" key on the keyboard to make it go away, and the 2nd. technique - about which I have a question - involves clicking anywhere on the screen outside of the text-field to make the keyboard go away.

Well in step#6 at the very top of pg. 163 we are instructed to add an IBOutlet as follows:

Code:

@interface KeyboardInputsViewController : UIViewController {
	IBOutlet UITextField *textField;
}

and then to connect this textField Outlet to the File's Owner in Interface Builder.

My question is: why did we not have to go through this and create an Outlet for textField (not to mention make it a @property and then also @synthesize it) in the 1st. technique?
Why do we have to do it now? What's the difference?

The admittedly rudimentary sense I get of this, having gone through it today and now just in playing around with it (assuming I understand your question) is that if you don't do this, there's no way for it to resign as First Responder.

It's still there, and it will still bring up the keyboard and accept input, put there seems to be no means of dismissing it.
