highlighting the text inside the textfield

Question

I want the text inside the textfield to be highlighted when I tap on it.

I want the original text to be deleted the moment someone tap on the numberpad. I tried using clearButtonMode but then since my textfield size is very small the cross icon fully occupy the textfield.

Any idea how to achieve this?

This can be achieved by

(void)textFieldDidBeginEditing:(UITextField *)iTextField {
    [iTextField selectAll:self];
}
