swift - 使用未解析的标识符 'tableView'

Question

I had an a problem with this code, this identifier didn't run with me

import UIKit

class RestaurantDetailViewController: UIViewController {


    @IBOutlet var restaurantImageView: UIImageView!
    var restaurantImage = ""

    override func viewDidLoad () {
        super.viewDidLoad ()

        restaurantImageView.image = UIImage(named: restaurantImage)
    }

    override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
        if segue.identifier == "showRestaurantDetail" {
            if let indexPath = tableView.indexPathSelectedRow {
                let destinationController = segue.destinationViewController as! RestaurantDetailViewController
                destinationController.restaurantImage = restaurantImageView[indexPath.row]
            }
        }
    }
}

错误是:使用了未解析的标识符“tableView”

寻找解决方案。谢谢，

Answer 1

prepareForSegue 方法显然在错误的类中(复制粘贴错误？)。

它属于主 Controller 。
