TouchScreenKeyboard works on android, not on ios?

Hi.

I am using Unity 5.2

I have a login screen and a signup screen.

On Android, for emails I change to email keyboard, for phone numbers I change to the number pad. The same code is not working when run on iOS.

I attach an EventTrigger for Select to the InputField, and I get it to call a function with this line (email version shown)

TouchScreenKeyboard.Open(texts[1].text, TouchScreenKeyboardType.EmailAddress);

What am I missing to get this to work on iOS? As I said, all my input fields on Android show the correct keyboard, iOS all show the same default keyboard.
