I've just created an in-app custom keyboard, got through all the difficult stuff, but am now stumped on (what is probably trivial):

how to connect the buttons of a XIB and its associated class so that the appropriate text is entered into a UITextView on a viewController.

I created a XIB with a keyboard so that I can reuse the same keyboard in different controllers. Set all the constraints, classes, file owner, etc. Everything works perfectly - except for getting data from the key to the view.

Here is what I have:

I've just created an in-app custom keyboard by placing a bunch of buttons in a XIB (so that I can reuse it in different controllers) but am stumped on (what is probably trivial):

how to connect the buttons of the XIB so that when I press one the appropriate text is entered at the cursor location in a UITextView on a viewController. (For example, if 5 is pressed, a 5 should be entered at the current cursor location in the UITextView.)

Everything works perfectly - except for getting data from the key to the view.

I do not want to create any extension that will require the user enabling it in Settings. I'd also like to place the keyboard where I want, in particular to restrict it to half the screen when the phone is rotated into Landscape.

I’m trying to build a simple todo app. Task screen is a table view controller and it’s cells contain the “check” button and textfield for user input. I’m trying to recreate some logic iPhone’s notes app has. After user taps return key on the keyboard a new cell creates. If textfield is empty and user taps backspace key current cell deletes. The first thing works just fine, but I can’t put my mind on the second one. I found some way to register tapping on backspace, but have problems with understanding how to call for deleting cell method I made in a table view controller.
