+# MessageKit Frequently Asked Questions
+
+**Why doesn't the `MessageInputBar` appear in my controller?**
+
+If you're using the `MessagesViewController` as a child view controller then
+you have to call `becomeFirstResponder()` on your view controller. The
+reason is because the `MessageInputBar` is the `inputAccessoryView` of the
+`MessagesViewController`. This means that it is not in the view hierarchy of
+`MessagesViewController`'s root view.
+
+```Swift
+class ParentVC: UIViewController {
+    override func viewDidLoad() {
+       super.viewDidLoad()
+       let childVC = MessagesViewController()
+       addChildViewController(childVC)
+       self.view.addSubview(childVC.view)
+       childVC.didMove(toParentViewController:self)
+       self.becomeFirstResponder()
+    }
+}
+```
+
+**How can I remove the `AvatarView` from the cell?**
+
+If you return `CGSize.zero` from the `MessagesLayoutDelegate` method
+`avatarSize(for:MessageType,at:IndexPath,in:MessagesCollectionView)`, the `AvatarView`
+will not be visible for that cell.
+
+```Swift
+func avatarSize(for: MessageType, at: IndexPath, in: MessagesCollectionView) -> CGSize {
+    return .zero
+}
+```
+
+**How can I dismiss the keyboard?**
+
+The `MessagesViewController` needs to resign the first responder.
+
+```Swift
+let controller = MessagesViewController()
+controller.resignFirstResponder()
+```
+
+**How can I get a reference to the `MessageType` in the `MessageCellDelegate` methods?**
+
+You can use `UICollectionView`'s method `indexPath(for: UICollectionViewCell)` to get the
+`IndexPath` for the `MessageCollectionViewCell` argument. Using this `IndexPath`, you can
+then get the `MessageType` for this cell through the `MessagesDataSource` method
+`messageForItem(at:IndexPath,in:MessagesCollectionView)`.
+
+```Swift
+func didTapMessage<T>(in cell: MessageCollectionViewCell<T>) {
+    guard let indexPath = cell.indexPath(for: cell) else { return }
+    guard let messagesDataSource = messagesCollectionView.messagesDataSource else { return }
+    let message = messagesDataSource.messageForItem(at: indexPath, in: messagesCollectionView)
+}
+```
