How do I make inputAccessoryView stay on screen when using drag to dismiss?

Question

I know that the view controller must be firstResponder in order for the inputAccessory to stay at the bottom. I am using a custom inputView / keyboard. I can manually dismiss it with a done button by removing the inputView but not resigning first responder. However when I enable the interactive drag to dismiss on my scrollview, the code automatically resigns first responder. So how can I use the interactive drag to dismiss and yet keep my viewcontroller as first responder? Anyone done this before? I thought maybe it is not possible and that I may need to make my own interactive drag to dismiss using a gesture recognizer.

More info: I have a button that swaps between standard keyboard and my custom one. I have seen dismissing these cause 2 keyboard did dismiss notifications. I thought I could become firstResponder in the keyboardDidHide method but this didn't work well since I couldn't tell the difference between when I manually dismissed the keyboard and when the interactive drag does it. This matters because I don't need to reload the input view or become first responder when I manually dismiss because I took care of it already.

Any suggestions would be amazing. I am trying to use inputView and inputAccessoryView on the UIViewController level.

Answer 1

Well after a day of pulling my hair, I have an answer.

Using the canResignFirstResponder of my viewcontroller did the trick. In viewWillAppear I set a BOOL responderOverride = YES;

In viewWillDisappear I call

responderOverride = NO; [self resignFirstResponder];

When the interactive drag on the scrollview tries to resignFirstResponder, canResignFirstResponder returns no which prevents my viewcontroller from resigning and keeps my input accessory retained and sitting at the bottom of the screen.

There is a lot of other code with reloading input views but since the real question was how to force a controller to stay first responder so we don't lose our input accessory view, then this solution works.

Answer 2

override var canBecomeFirstResponder : Bool {
     get {
           retrun true
      }
}

This works for me
