如何进一步缩短三元运算符

Question

我正在尝试清理我的代码，目前有这个三元条件。我想再次清理和重构它并使其简短。我该如何应对？

let user = AppDelegate.shared.user!.userID
let messageSender = customMessage.sender.userID
let sender = (user == messageSender)

myCell = sender ? tableView.dequeueReusableCell(withIdentifier: "firstCell", for: indexPath) : tableView.dequeueReusableCell(withIdentifier: "secondCell", for: indexPath)

Answer 1

看看这个：

let cellName = (user == messageSender) ? "firstCell" : "secondCell"
myCell = tableView.dequeueReusableCell(withIdentifier: cellName, for: indexPath)

Answer 2

let user = AppDelegate.shared.user!.userID
let messageSender = customMessage.sender.userID
let sender = (user == messageSender)
let reuseIdentifier = sender ? "firstCell" : "secondCell"
let myTableView = sender ? tableView : pTableView

myCell = myTableView.dequeueReusableCell(withIdentifier: reuseIdentifier, for: indexPath)
