I'm struggling to find a way to display the username in the MessageKit chat view controller. I copied the MessagesDataSource from the example project with no luck. Here's what my MessagesDataSource currently looks like:
extension ChatViewController: MessagesDataSource {
func currentSender() -> Sender {
//guard let currentUserID = User.current?.key else {return nil}
let newSender = Sender(id: (User.current?.key)!, displayName: (User.current?.username)!)
return newSender
}
func numberOfSections(in messagesCollectionView: MessagesCollectionView) -> Int {
//return 1
return messages.count
}
func messageForItem(at indexPath: IndexPath, in messagesCollectionView: MessagesCollectionView) -> MessageType {
return messages[indexPath.section]
}
func cellTopLabelAttributedText(for message: MessageType, at indexPath: IndexPath) -> NSAttributedString? {
return NSAttributedString(string: MessageKitDateFormatter.shared.string(from: message.sentDate), attributes: [NSAttributedString.Key.font: UIFont.boldSystemFont(ofSize: 10), NSAttributedString.Key.foregroundColor: UIColor.darkGray])
}
func messageTopLabelAttributedText(for message: MessageType, at indexPath: IndexPath) -> NSAttributedString? {
let name = message.sender.displayName
return NSAttributedString(string: name, attributes: [NSAttributedString.Key.font: UIFont.preferredFont(forTextStyle: .caption1)])
}
func messageBottomLabelAttributedText(for message: MessageType, at indexPath: IndexPath) -> NSAttributedString? {
let dateString = formatter.string(from: message.sentDate)
return NSAttributedString(string: dateString, attributes: [NSAttributedString.Key.font: UIFont.preferredFont(forTextStyle: .caption2)])
}
}
If I place a breakpoint after let name = message.sender.displayName the proper username is displayed in the console output. However, it still doesn't appear in the chat history. The chat view still only displays the avatar and the message, nothing else.
What am I missing?
Thanks
Altho i don't know what, version of MessageKit you use, but i am pretty sure if you tried this everything should work just fine,
func cellTopLabelAttributedText(for message: MessageType, at indexPath: IndexPath) -> NSAttributedString? {
let name = message.sender.displayName
return NSAttributedString(
string: name,
attributes: [
.font: UIFont.preferredFont(forTextStyle: .caption1),
.foregroundColor: UIColor(white: 0.3, alpha: 1)
]
)
}
As i don't see any dataSource function that's called messageTopLabelAttributedText
