Send button not functioning
We're using latest version of this tutorial.
`import UIKit import MessageKit
class MainVC: MessagesViewController {
var messages: [Message] = []
var member: Member!
override func viewDidLoad() {
super.viewDidLoad()
member = Member(name: "Guest", color: .green)
messagesCollectionView.messagesDataSource = self
messagesCollectionView.messagesLayoutDelegate = self
messageInputBar.delegate = self
}
}
extension MainVC: MessagesDataSource {
func numberOfSections( in messagesCollectionView: MessagesCollectionView) -> Int {
return messages.count
}
func currentSender() -> SenderType {
return Sender(id: member.name, displayName: member.name)
}
func messageForItem(
at indexPath: IndexPath,
in messagesCollectionView: MessagesCollectionView) -> MessageType {
return messages[indexPath.section]
}
func messageTopLabelHeight(
for message: MessageType,
at indexPath: IndexPath,
in messagesCollectionView: MessagesCollectionView) -> CGFloat {
return 12
}
func messageTopLabelAttributedText(
for message: MessageType,
at indexPath: IndexPath) -> NSAttributedString? {
return NSAttributedString(
string: message.sender.displayName,
attributes: [.font: UIFont.systemFont(ofSize: 12)])
}
}
extension MainVC: MessagesLayoutDelegate { func heightForLocation(message: MessageType, at indexPath: IndexPath, with maxWidth: CGFloat, in messagesCollectionView: MessagesCollectionView) -> CGFloat { return 0 } }
extension MainVC: MessageInputBarDelegate { func messageInputBar( _ inputBar: MessageInputBar, didPressSendButtonWith text: String) {
let newMessage = Message(
member: member,
text: text,
messageId: UUID().uuidString)
messages.append(newMessage)
inputBar.inputTextView.text = ""
messagesCollectionView.reloadData()
messagesCollectionView.scrollToBottom(animated: true)
}
}`
Nothing happens when I click on send button.,
