swift UI专项训练9 添加数据

  今天我们来实现新增数据的功能。在新增餐馆的控制器中初始化一个类：

 var restaurant = Restaurant()

会自动生成如下代码：

@IBOutlet weak var doneButton: UIBarButtonItem!

 override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
        // Get the new view controller using segue.destinationViewController.
        // Pass the selected object to the new view controller.
        
        if sender as NSObject == doneButton {
            if(!textField.text.isEmpty){
            restaurant.name = textField.text
            }
        }
    }

 @IBAction func unwindToList(segue:UIStoryboardSegue){
    let source = segue.sourceViewController as AddRestaurantViewController
       let r1 = source.restaurant
        if r1.name != "" {
        restaurantList.append(r1)
        }
    }
