botCell.textLabel!.lineBreakMode = .byWordWrapping
botCell.textLabel!.text = botMessagesData[indexPath.row]
botCell.textLabel!.textAlignment = .left
return botCell;
}
}
}
That is my code. I need to do something for this code to works. If I'll delete one of functions, that will work I can not understand, how to change my code to work. Please, help
You need
public func tableView(_ chatHistory: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let item = arr[indexPath.row]
if item.isUser {
let userCell = chatHistory.dequeueReusableCell(withIdentifier: "userMessage")! as UITableViewCell
userCell.textLabel!.textColor = UIColor(red:0.00, green:0.33, blue:0.62, alpha:1.0)
userCell.textLabel!.numberOfLines = 0
userCell.textLabel!.lineBreakMode = .byWordWrapping
userCell.textLabel!.text = item.messsage
userCell.textLabel!.textAlignment = .right
return userCell
}
else {
let botCell = chatHistory.dequeueReusableCell(withIdentifier: "botMessage")! as UITableViewCell
botCell.textLabel!.textColor = UIColor(red:0.00, green:0.33, blue:0.62, alpha:1.0)
botCell.textLabel!.numberOfLines = 0
botCell.textLabel!.lineBreakMode = .byWordWrapping
botCell.textLabel!.text = item.message
botCell.textLabel!.textAlignment = .left
return botCell
}
}
struct Item {
let isUser:Bool
let message:String
}
Where arr
var arr = [Item]()
You need to return the same returning type that you declared in your function,
func botMessage() -> Void //returns void
while you're returning a UITableViewCell
. replace Void
with UITableViewCell
.
Also i have noticed you have sub function that returns Int
remove that function is unnecessary.
