安装

类库开源地址：https://github.com/sascha/DrawerController

可惜的是，它已经不维护了，很好用的一个侧滑实现

pod 'DrawerController'

新建侧滑视图

import UIKit

// 这个类就是一个 UIViewController 可以在里面写任何你想写的东西
class LeftViewController: UIViewController {

  override func viewDidLoad() {
    super.viewDidLoad()
    self.title = "Left Menu"
    self.view.backgroundColor = .white
  }

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

修改 AppDelegate 类

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    
  let drawerController = DrawerController(centerViewController: UINavigationController(rootViewController: ViewController()), leftDrawerViewController: UINavigationController(rootViewController: LeftViewController()))
  
  // 侧滑打开宽度
  drawerController.maximumLeftDrawerWidth = 250
  // 打开侧滑手势
  drawerController.openDrawerGestureModeMask = .all
  // 关闭侧滑手势
  drawerController.closeDrawerGestureModeMask = .all
  
  self.window?.rootViewController = drawerController
  return true
}

Navigation上添加按钮

修改 ViewController

import UIKit

class ViewController: UIViewController {

  override func viewDidLoad() {
    super.viewDidLoad()
    self.title = "DrawerDemo"
    self.view.backgroundColor = .white
    
    // 给导航条添加一个按钮
    self.navigationItem.leftBarButtonItem = UIBarButtonItem(image: UIImage(named: "baseline-menu-48px"), style: .plain, target: self, action: #selector(ViewController.openLeftMenu))
    
    self.navigationController?.navigationBar.barStyle = .default
    // menu icon默认是蓝色，下面将其改成黑色的
    self.navigationController?.navigationBar.tintColor = .black
  }
  
  @objc func openLeftMenu() {
    // 打开drawerController
    self.navigationController?.evo_drawerController?.toggleLeftDrawerSide(animated: true, completion: nil)
  }

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