iPad: Better way than invisible button on background to let users exit entries?

Question

On iPad/iPhone, Do you still need to make an invisible button on background to let users exit entries? Is there a better way to dismiss the keyboard when users click outside of an entry?

Answer 1

I use

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event

in the ViewController to call resignFirstResponder on the active control from there.

// edit:

My Views contain several UITextFields; I want the keyboard to disappear when the user touches anywhere besides a TextField or the keyboard, so my ViewController has this:

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    [currentTextfield resignFirstResponder];
}

This causes the keyboard to disappear. (I keep track of the current textfield elsewhere.)
