Swift-左右侧滑菜单

Swift-左右侧滑菜单.gif

这是我之前写的项目中用到过的一个侧滑菜单库，今天又把他做成了是一个Demo，拿来和大家分享。

首先，新建一个Podfile文件，pod 'KGFloatingDrawer' 这个库

platform :ios, '9.0'
use_frameworks!

target 'Swift-左右侧滑菜单' do
pod 'KGFloatingDrawer', '~> 0.2.0'
end

然后在你的AppDelegate中import KGFloatingDrawer

import UIKit
import KGFloatingDrawer

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?
    
    /*你storyboard的名字*/
    let kKGDrawersStoryboardName = "Main"
    /*想设置的背景图片的名字*/
    let backgroundImgName = "login3"
    /*主视图StoryboardId*/
    let kKGDrawerSettingsViewControllerStoryboardId = "center"
    /*左视图StoryboardId*/
    let kKGLeftDrawerStoryboardId = "left"
    /*右视图StoryboardId*/
    let kKGRightDrawerStoryboardId = "right"

    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
        
        window = UIWindow(frame: UIScreen.mainScreen().bounds)
        
        window?.rootViewController = drawerViewController
        
        window?.makeKeyAndVisible()
        
        return true
    }

    /*
     *****************
     *      *        *
     *****************
     */
    private var _drawerViewController: KGDrawerViewController?
    var drawerViewController: KGDrawerViewController {
        get {
            if let viewController = _drawerViewController {
                return viewController
            }
            return prepareDrawerViewController()
        }
    }
    
    func prepareDrawerViewController() -> KGDrawerViewController {
        let drawerViewController = KGDrawerViewController()
        
        drawerViewController.centerViewController = drawerSettingsViewController()
        drawerViewController.leftViewController = leftViewController()
        drawerViewController.rightViewController = rightViewController()
        drawerViewController.backgroundImage = UIImage(named: backgroundImgName)
        
        _drawerViewController = drawerViewController
        
        return drawerViewController
    }
    
    private func drawerStoryboard() -> UIStoryboard {
        let storyboard = UIStoryboard(name: kKGDrawersStoryboardName, bundle: nil)
        return storyboard
    }
    
    private func viewControllerForStoryboardId(storyboardId: String) -> UIViewController {
        let viewController: UIViewController = drawerStoryboard().instantiateViewControllerWithIdentifier(storyboardId)
        return viewController
    }
    
    func drawerSettingsViewController() -> UIViewController {
        let viewController = viewControllerForStoryboardId(kKGDrawerSettingsViewControllerStoryboardId)
        return viewController
    }
    
    
    private func leftViewController() -> UIViewController {
        let viewController = viewControllerForStoryboardId(kKGLeftDrawerStoryboardId)
        return viewController
    }
    
    private func rightViewController() -> UIViewController {
        let viewController = viewControllerForStoryboardId(kKGRightDrawerStoryboardId)
        return viewController
    }
    
    func toggleLeftDrawer(sender:AnyObject, animated:Bool) {
        _drawerViewController?.toggleDrawer(.Left, animated: true, complete: { (finished) -> Void in
            // do nothing
        })
    }
    
    func toggleRightDrawer(sender:AnyObject, animated:Bool) {
        _drawerViewController?.toggleDrawer(.Right, animated: true, complete: { (finished) -> Void in
            // do nothing
        })
    }
    
    private var _centerViewController: UIViewController?
    var centerViewController: UIViewController {
        get {
            if let viewController = _centerViewController {
                return viewController
            }
            return drawerSettingsViewController()
        }
        set {
            if let drawerViewController = _drawerViewController {
                drawerViewController.closeDrawer(drawerViewController.currentlyOpenedSide, animated: true) { finished in }
                if drawerViewController.centerViewController != newValue {
                    drawerViewController.centerViewController = newValue
                }
            }
            _centerViewController = newValue
        }
    }
    
    /*
     *****************
     *      *        *
     *****************
     */

之后像我图片这样创建一个主视图，一个左视图，和一个右视图，并设置设置storyboard ID

最后给左右两个按钮绑定滑动事件

import UIKit
import KGFloatingDrawer

class ViewController: UIViewController {

    /*左滑动按钮*/
    @IBAction func left(sender: UIBarButtonItem) {
        
        let appDelegate = UIApplication.sharedApplication().delegate as! AppDelegate
        appDelegate.drawerViewController.toggleDrawer(KGDrawerSide.Left, animated: true) { (finished) -> Void
            in
        }
        
    }
    
    /*右滑动按钮*/
    @IBAction func right(sender: UIBarButtonItem) {
        
        let appDelegate = UIApplication.sharedApplication().delegate as! AppDelegate
        appDelegate.drawerViewController.toggleDrawer(KGDrawerSide.Right, animated: true) { (finished) -> Void
            in
        }
        
    }

OK，搞定！
