keyboard error show

keyboard shows keys with the value zero. Application published in the App Store, on some occasions shows the entire keyboard filled with number zero on the keyboards. My keyboard configuration is for shows with the numerical layout.

Is zero the value displayed on keys or keys size ?


If the latter, then look here : h ttps://stackoverflow.com/questions/45689664/ios-11-keyboard-height-is-returning-0-in-keyboard-notification


If the former, what happens when you type a key ? Is the correct value input or do you get 0 in all cases ?
