Customizing inputAccessoryView on iOS for Entry, Editor and HybridWebView html <textarea>

[hflexgrig]

Here, I’d like to share the results of several intense days spent customizing InputAccessoryView for iOS input controls—particularly for HTML text inputs inside a HybridWebView. This turned out to be even more challenging than implementing share extensions, which says a lot.

I hope this repository helps others avoid the same pitfalls and saves them a significant amount of time. :)

This is how it looks by default ( blue rounded button with a white checkmark, which dismisses the keyboard when tapped and for hyrbidwebview large semi-transparent white panel above the keyboard, featuring up and down arrow buttons on the left and a checkmark button on the right)

And this is after customizing it

My real app was accepted by Apple for distribution, but there was a real risk of getting rejection because private UIKit / WebKit internals in several ways that Apple explicitly flags as unsafe. Also method swizzling of private classes ("WkContentView", "_WKContentView", "WKScrollView")...

Here is the repo i've created https://github.com/hflexgrig/CustomInputAccessoryViewInMAUIiOS
