UGUI - How to use InputField.ContentType.Custom?

I have a “direct connect to server” InputField in my UI for the user to input a server’s IP address. On Mobile, I don’t want to use the default keyboard. I want to use the numbers and punctuation keyboard, so I’d like to specify the keyboard to use. I gather the best way is to set the InputField’s ContentType property to custom, but the only documentation I have found is…

InputField.ContentType.Custom
Description

Custom types that allows user-defined settings.

Does anyone know how to setup a custom ContentType?

Thanks!

I never did find out how to setup a custom ContentType. Having said that, I was able to programmatically just set the InputField’s KeyboardType as such…

myInputField.keyboardType = TouchScreenKeyboardType.NumbersAndPunctuation;
