In our company iPhone app, we are using Number Pad keyboard with a custom button hyphen "-". Throughout the iOS versions, we had to modify the code as below. Until up to iOS 10, the code below worked fine, but we are having an issue in iOS11. when i tap on the textbox on screen #1, the keypad along with "-" displays as expected. When i hit the enter button on that same screen #1, the app takes me to screen #2, but when i hit the back button on screen # 2, and tap on that same textbox in screen #1, the keypad does display again but the hyphen key does not. Hope you can help. thank you. We are also looking for a permanent solution for this so that we don't have to revisit the same issue in iOS12 etc..
