Question

I have created a custom keyboard and I have two text fields. When the user clicks on one of them, the keyboard appears.

How can I know which text field is currently active so that I write what the user is typing from the keyboard?

Answer 1

This is how I would do:

Tag both textfields (or use properties)

textField1.tag = 100;
textField2.tag = 101;

Also set their delegates.

textField1.delegate = self;
textField2.delegate = self;

On the .h file declare your class will implement the UITextFieldDelegate Protocol

and on the .m

- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField
{
    if (textField.tag == 100) //you should use a constant instead of 100
    {
        //set a breakpoint here so you would know your typing the first textField
        return YES;
    }
}
