[GitHub] [cordova-ios] nekobungi opened a new issue #1132: App is not listening any keyboard input until the screen is tapped

[GitBox <gi...@apache.org>]

nekobungi opened a new issue #1132:
URL: https://github.com/apache/cordova-ios/issues/1132


   # Bug Report
   
   ## Problem
   Just after launch, the app will not accept any keyboard input, no matter what keybord event listeners you have added.
   However, if you tap or click the screen even once, all keybord events will start to be listening.
   
   This may not be a problem for many apps that are primarily made for the iPhone, since they mainly works with touch screens.
   
   However, in recent years, as Apple has started to feature more keyboards for the iPad, and iOS apps are now running on Macintosh, non-touch screen based operation has become more and more important.
   
   Unfortunately, the need to tap the screen with this bug makes it currently impossible to create an app such as utility app operated using only the keyboard, or gaming app playing via keyboard.
   
   ### What is expected to happen?
   Listen to keyboard input right after app launch.
   
   ### What does actually happen?
   Keyboard input will not start listening until you tap or click the screen.

   ```
   3. Build and launch the app on an iPad with keyborad connected, a Mac, or a simulator
