[New Feature Request?] New InputSystem Keyboard KeyUp on iOS 13+

Hello there!

Abstract: Unity could use Keyboard KeyDown and KeyUp events for iOS 13+, instead of Keyboard Shortcuts!

Unity's new Input System listens to keystrokes on iOS by using Keyboard Shortcuts. This is an extremely limited implementation that suffers from a lack of proper KeyUp events: from what I understand they need to be timed out.

This means that repeated key strokes will be "debounced" (when happening within about half a second).

There is a way to listen to each key stroke and that is by using:
keyboard.onTextInput += new Action<char>(MyCallBackFunction);

-- but -- this also doesn't work completely... arrow keys will trigger a long series of events, for each character in the phrase "UIInputKeyUp".... instead of a single char code for the arrow key.

Now, by looking at the following web page, it seems that a new, much better implementation could be integrated:

At the current rate of one non preview release per year for the input package, I think there is a good chance your feature request will be implemented sometime in the next decade. Look forward to it.

 

Yep, I'm suffering from this now, all I want to do is have the user type letters in iOS and have them come up. Not a complex task you'd think. The new input system doesn't detect the keystrokes at all. The legacy one does, but fails to detect a repeated press of one key within half a second of the last. Anyone who types with more than one finger does it quicker than that, so the keypress is dropped, it's very frustrating.

Would there be a way to edit the code in the generated xcode project to use this? The file:

Build Folder\Classes\UI\UnityView+Keyboard.mm

is the one that does the timeout/debouncing, but I'm no Objective-C++ person. Anyone know how we'd do it?

 

The rate of releases has increased since my post last year, so my new prediction is that you might have to wait only 3 more years until a basic feature is implemented.
