Swift xcode错误：'DetailViewController'类型的值没有成员'Animal'

Question

我正在尝试使用动物列表制作一个快速项目，然后当您点击其中一行时，您会被转移到另一个窗口，在那里它会告诉您动物的描述。

如果屏幕截图太小，以下是代码：

{
    {
        length: 10,
        title: 'test 1',
        price_total: 200.99,
    },
    {
        length: 3,
        title: 'test 2',
        price_total: 3.99,
    },
}

DetailViewController类代码：

import UIKit
class AnimalListTableViewController: UITableViewController
{
    override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return 4
    }

    override func prepareForSegue(segue: UIStoryboardSegue,
        sender: AnyObject?)
    {
        if let detailViewController = segue.destinationViewController as? DetailViewController, let indexPath = self.tableView.indexPathForSelectedRow {
            detailViewController.Animal = animals[indexPath.row] //this is where I get the error that says "Value of type 'DetailViewController' has no member 'Animal"
        }
    }
}

ListOfAnimals类代码：

import UIKit


class DetailViewController: UIViewController
{
    @IBOutlet weak var titleLabel: UILabel!
    @IBOutlet weak var descriptionLabel: UILabel!
    var animal: Animal?
    var a = Animal?()


    override func viewWillAppear(animated: Bool)
    {
        titleLabel.text = a!.name
        descriptionLabel.text = a!.longDescription
    }



    override func viewDidLoad()
    {
        viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
    }

    override func didReceiveMemoryWarning()
    {
        didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }



}

Answer 1

使用：

detailViewController.animal

而不是：

detailViewController.Animal
