activate return key on keyboard when UITextField is empty?

[chuck]

I currently have an address form where a user has to enter Street Line 1 (required) and then advances to Street Line 2 (optional). The problem is that if nothing is entered in this field, the Next button is disabled. Is there any way to enable the return key on the keyboard when nothing is entered in its text field?

I haven't tryed it but I'm sure you could check with an IF string is @"" kinda thing and maybe have a read through this: Removing Keyboard when done

To dissmiss the keyboard without the return key, you could :

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

   if (theTextField.editing == YES) {

           [theTextField resignFirstResponder];

   }

}

By the way, I wrote from my memory so there might be an error in spelling or something but o hope you get the idea

Make sure that your header interface invokes <UITextViewDelegate>

- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range 
 replacementText:(NSString *)text
{
	if([text ...){
               textView.text = ...
        }
	return NO;
}

You can use the Range information too.

I guess you use IB. Uncheck auto-enable return key - that's all.
