How to remove manually button on IOS

[bstuelp]

I need to remove manual button bottom in my app. I have use this code but "suppressManual" seems doesn't work for IOS (android it is ok):

CardIO.scan({
"expiry" : true,
"cvv" : false,
"zip" : false,
"suppressConfirm" : true,
"suppressManual" : true,
"hideLogo" : true
}, onCardIOComplete, onCardIOCancel);

Can anyone help me? Thanks in advance!
