Question

I have two text fields and a button on my view.

In the first text field, user enters some value in celsius and by clicking on the button, user is able to find the fahrenheit value on the other textfield. This works fine.

However, when user enters another celsius value in the first textfield, at the touch of the button the fahrenheit value is APPENDED to the previous fahrenheit value, instead of changed.

Answer 1

in your button action function

 farenheitTextField.text=nil;

[farenheitTextField setClearsOnBeginEditing:YES];

 farenheitTextField.text=@"your calculated value";
