How To Disable Auto-capitalization when using TouchScreenKeyboard

Core Question:

How do I disable auto-capitalization when using TouchScreenKeyboard.

Our game contains various text-fields for purposes such as entering usernames, passwords, and e-mail addresses. When they are used on mobile devices, the first letter of the entry often defaults to being capitalized. I’ve been looking into the API but I haven’t found any way to disable this function. We are using the NGUI middleware, but I’ve looked into the TouchScreenKeyboard class myself and I haven’t found any options to help with this issue.

I really want to know too, But you need to go deeper like this
