AppDelegate:

    self.window?.makeKeyAndVisible()
    //创建导航视图控制器的根视图
    let vc = ViewController()
    //2.创建导航视图控制器，并为她制定根视图控制器
    let navigation = UINavigationController(rootViewController: vc)
    
    //3.将导航视图控制器设置为window的根视图控制器
    self.window?.rootViewController = navigation

secondViewController.swift:
class secondViewController: UIViewController {

var label1 : UILabel!
var label2:UILabel!
var textfield1:UITextField!
var textfield2:UITextField!

//定义要传值的类型的属性  属性传值第一步

Person.swift:
