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
}

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.
    }

}
