CoronaCards (Corona in native apps) CoronaCards for iOS / Android
#1

I created an app for iOS using CoronaCards.
And I used native.newTextField.
But it doesn’t show the text on iPhone 4, 5. it is only showed iPhone 6. Their iOS version are 9.x.
(TextField was created. but text of it is not showed)
How can i fix it?
