Disable Return button of`Uitextfield`

Question

Is there any way, no whining, to disable the Return button of a UITextField?

I have a screen with two UITextField, a text and a numeric, I need the keyboard to be activated directly and I need the Return button of the text field to be disabled, so that the keyboard does not close when pressing it.

Answer 1

What you can do to prevent this is to use the delegate textFieldShouldReturn: of Uitextfield, so for example:

- (BOOL)textFieldShouldReturn:(UITextField *)textField {
    return NO;
}

At least in the iPhone, the "Return" button itself has no automatic action, until you set one in this same delegate. In the iPad, I believe that the standard function is [textField resignFirstResponder] but you can prevent that too.

Answer 2

The way to disable the action of the Return is to use delegate as @Paulo replied. But, you cannot simply lock the open keyboard in a view. This goes against good usability standards and against Apple’s usability document.

I recommend that you do a check of which Uitextfield is making the call and acting accordingly.

For example, if it is the text that called the Return, change the focus to the numeric and, if it is the numeric, collect the keyboard.

- (BOOL) textFieldShouldReturn:(UITextField *)textField {
    if(textField == self.texto) {
        [self.numero becomeFirstResponder];   
    }else {
        [textField resignFirstResponder];
    }
    return NO;
}
