AppDelegate中:

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {

// Override point for customization after application launch.

let master = MasterViewController()

let detail = DetailViewController()

master.detailViewController = detail

let navigationController = UINavigationController(rootViewController: master)

//判断设备

if UIDevice.current.userInterfaceIdiom == .phone{

self.window?.rootViewController = navigationController

}else{

//创建分割视图控制器（iPad特有）

let split = UISplitViewController()

//横屏下显示

split.viewControllers = [navigationController,detail]

self.window?.rootViewController = split

}

return true

}

创建MAsterViewController：

import UIKit

class MasterViewController: UIViewController,UITableViewDelegate,UITableViewDataSource {

var tableView:UITableView!

var ctrls = ["A","B","C"]

var detailViewController:DetailViewController!

override func viewDidLoad() {

super.viewDidLoad()

self.title = "列表"

self.tableView = UITableView(frame: self.view.frame,style:.plain)

self.tableView.delegate = self

self.tableView.dataSource = self

self.tableView.register(UITableViewCell.self, forCellReuseIdentifier: "ReusedCell")

self.view.addSubview(tableView)

}

func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {

return ctrls.count

}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

let identifier = "ReusedCell"

let cell = tableView.dequeueReusableCell(withIdentifier: identifier, for: indexPath)

cell.accessoryType = .disclosureIndicator

cell.textLabel?.text = self.ctrls[indexPath.row]

return cell

}

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {

detailViewController!.loadControl(ctrl: self.ctrls[indexPath.row])

//        detailViewController.title = ctrls[indexPath.row]

if (UIDevice.current.userInterfaceIdiom == .phone){

tableView.deselectRow(at: indexPath, animated: true)

self.navigationController?.pushViewController(detailViewController, animated: true)

}

}

}

DetailViewController：

import UIKit

class DetailViewController: UIViewController {

override func viewDidLoad() {

super.viewDidLoad()

self.view.backgroundColor = UIColor.white

let ctrl = self.title != nil ? self.title! : ""

loadControl(ctrl: ctrl)

}

func loadControl(ctrl:String){

clearViews()

switch ctrl {

case "A":

let label = UILabel(frame: self.view.bounds)

label.backgroundColor = UIColor.black

label.textColor = UIColor.orange

label.text = "hellow"

self.view.addSubview(label)

case "B":

let button = UIButton(frame: CGRect(x: 150, y: 250, width: 100, height: 100))

button.setTitle("按钮", for: .normal)

button.backgroundColor = UIColor.red

self.view.addSubview(button)

case "C":

let uiSwitch = UISwitch(frame: CGRect(x: 150, y: 250, width: 0, height: 0))

uiSwitch.setOn(false, animated: true)

self.view.addSubview(uiSwitch)

default:

print("error")

}

}

func clearViews(){

for v in self.view.subviews{

v.removeFromSuperview()

}

}

}
