Question

I am trying to set up a custom formatter (named TextFieldFormatter) for my text fields, limiting them to 3 characters maximum and only allowing decimal values. TextFieldFormatter is a subclass of NSFormatter and my textfields are NSTextFields. I’m using the method isPartialStringValid:newEditingString:errorDescription: to do my formatting.

The problem that I am having right now, is that I do not know how to link TextFieldFormatter to the text fields.

So, how can I do this?

You can set the formatter property programmatically, or you can create an NSObject in IB, set its class to TextFieldFormatter, and then tie the formatter property to it in IB.
