What happened?

When I go to ChatViewController and come back to previous ViewController, the input bar at the bottom is still available with the following warning/error message

[View] First responder warning: '<MessageKit.InputTextView: 0x7fcf6689ea00; baseClass = UITextView; frame = (12 6; 291 30); text = ''; clipsToBounds = YES; gestureRecognizers = <NSArray: 0x60000064ff30>; layer = <CALayer: 0x600000628fc0>; contentOffset: {0, 0}; contentSize: {0, 28.5}; adjustedContentInset: {0, 0, 0, 0}>' rejected resignFirstResponder when being removed from hierarchy

What did you expect to happen?

The Input Bar must be removed once I navigate away from ChatViewController. I am not sure what is causing this. I am using IQKeyboardManager and I tried disabling it. The problem still exist.

Upon further testing, this issue is a conflict with IQKeyboardManager and related to #309

The solution to this issue is to disable IQKeyboardManager in the viewDidDisappear() instead of viewWillDisappear() here is the code for reference.

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
    IQKeyboardManager.sharedManager().enable = false
}

override func viewDidDisappear(_ animated: Bool) {
    super.viewDidDisappear(animated)
    IQKeyboardManager.sharedManager().enable = true
}

Since this remains solved. I am closing this issue.
