SSDrawerViewController

What is this for?

MSDynamicDrawerViewController is written in Objective-C. So, I convert it and write in Swift.
This is integrated with UIKit Dynamics APIs(new in iOS7).
For a detail, you can refer the MSDynamicDrawerViewController.

Requirements

• iOS 8.1+
• Swift 3.0+

Installation

Manual Import

Just drag these sources into your project.
I'll support Cocoapods or Carthage ASAP.

Usage

The usage of SSDrawerViewController is same with MSDynamicDrawerViewController.
But, compared to MSDynamicDrawerViewController, SSDrawerViewController is written in Swift.
As a result, the usage is slightly different depends on each language's syntax.

So, I'd like to share my use case in Swift 3.

// AppDelegate.swift

class AppDelegate: UIResponder, UIApplicationDelegate, SSDrawerViewControllerDelegate {
    ...
    var window: UIWindow?
    var drawerController: SSDrawerViewController?
    var isDrawable: Bool = true
    ...

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    ...
        // DrawerViewController
        self.drawerController = self.window!.rootViewController as? SSDrawerViewController
        self.drawerController?.delegate = self
        self.drawerController?.addStylerFromArray([SSDrawerScaleStyler.styler(), SSDrawerFadeStyler.styler(), SSDrawerShadowStyler.styler()], forDirection: SSDrawerDirection.Left)

        let menuViewController: SSMenuViewController = (self.window?.rootViewController?.storyboard?.instantiateViewController(withIdentifier: "MenuViewController") as? SSMenuViewController)!
        menuViewController.drawerViewController = self.drawerController
        self.drawerController?.setDrawerViewController(menuViewController, forDirection: SSDrawerDirection.Left)

        // Transition to the first view controller
        menuViewController.transitionToViewController()

        self.window?.rootViewController = self.drawerController
        self.window?.makeKeyAndVisible()
    ...
    }
    
    ...
    
// MARK: - SSDrawerViewControllerDelegate

    func drawerViewController(_ drawerViewController: SSDrawerViewController, mayUpdateToPaneState paneState: SSDrawerMainState, forDirection direction: SSDrawerDirection) {
        print("Drawer view controller may update to state `\(paneState)` for direction `\(direction)`")

        if paneState == .open {
            if let menuViewController = drawerViewController.drawerViewController as? SSMenuViewController {
                if let headerView = menuViewController.menuTableView.headerView(forSection: 0) as? SSMenuHeadView {
                    headerView.configView()
                }
            }
        }
    }

    func drawerViewController(_ drawerViewController: SSDrawerViewController, didUpdateToPaneState paneState: SSDrawerMainState, forDirection direction: SSDrawerDirection) {
        print("Drawer view controller did update to state `\(paneState)` for direction `\(direction)`")
    }

    func drawerViewController(_ drawerViewController: SSDrawerViewController, shouldBeginPanePan panGestureRecognizer: UIPanGestureRecognizer) -> Bool {
        return self.isDrawable
    }
}

// SSMenuViewController.swift

class SSMenuViewController: UIViewController {
    ...
    weak var drawerViewController: SSDrawerViewController?
    ...
    func transitionToViewController() -> Void {
        let animateTransition: Bool = self.drawerViewController?.mainViewController != nil

        let mainNavigationController: UINavigationController = (UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "MasterNavigationController") as? UINavigationController)!

        self.drawerViewController?.setMainViewController(mainNavigationController, animated: animateTransition, completion: nil)
    }
}
