调用中的RxCocoa额外参数

Thanks to Philip Laine answer above: https://stackoverflow.com/a/36536320/2126233

That helped me see that I was making a mistake in regards to what I was observing. It helped me to see the problem I was having in my code.

If you just want to bind to a normal tableViewCell then you need to use tableView.rx_itemsWithCellFactory:

currentQuestion.asObservable()
        .bindTo(tableView.rx_itemsWithCellFactory) {(tableView, row, item) in
            let cell = UITableViewCell()
            cell.textLabel?.text = item.distance

            return cell

        }.addDisposableTo(disposeBag)

If you are using a custom cell then you can use tableView.rx_itemsWithCellIdentifier("ChoiceCell", cellType: ChoiceCell.self). Here is an example:

 currentQuestion
     .asObservable()
     .filter { $0 != nil }
     .map { $0!.choices }
  .bindTo(tableView.rx_itemsWithCellIdentifier("ChoiceCell", cellType: ChoiceCell.self)) { (row, element, cell) in
   cell.choiceModel = element
 }
 .addDisposableTo(disposeBag)

For me I was still getting this same error unless I had a property inside the tableView cell that matched the element that was coming out of the array I was binding the tableView to.

So if you have an array of [Taxis] like so then inside the tableViewCell I required a variable that stored a Taxis. Then I was able to compile my project.

So in ChoiceCell I have a var like so:

var taxi: Taxi? {
    didSet {
        layoutCell()
    }

}

我希望这可以帮助其他任何将tableViewCell绑定到数组的问题。
