setTextColor doesn't work.

https://docs.coronalabs.com/daily/api/type/TextField/setTextColor.html

I used native.newTextField() in CoronaCards iOS.

setTextColor doesn’t work.

If I use it, text doesn’t show.

My code is…
 

local snTxt = native.newTextField( 0, 0, 230, 40 )

snTxt.inputType = “UIKeyboardTypeASCIICapable”

snTxt.isFontSizeScaled = true

snTxt.hasBackground = false

snTxt.text = “0123456”

snTxt:setTextColor(1, 0, 0, 1)

Version is CoronaCards 2016.2908.
