setting the value of other textfields to nil

I am trying to have 6 textfields that requires only one textfield to be filled in order to calculate the value of the second textbox. however i would like the textbox that are empty and arent used to not display 0.00000 but instead remain empty. how can this开发者_StackOverflow be done? thanks

We need more information - why do the text fields contain 0.000000 to start with?

Because the code to clear a text field is pretty simple I think we don't understand your question :)

[myTextField setText:@""];
