YQSlideDrawerController

参考ICSDDrawer写的一个侧边框，使用swift2.1

使用方法 left和center必须实现YQDrawerDelegate方法

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    // Override point for customization after application launch.
    window = UIWindow(frame: UIScreen.mainScreen().bounds)
    window?.backgroundColor = UIColor.blackColor()
    
    
    let colorsVC = YQLeftViewController()
    let plainColorVC = YQCenterViewController()
    
    let drawer:YQDrawerViewController = YQDrawerViewController()
    drawer.drawerDelegateLeft = colorsVC.self
    drawer.drawerDelegateCenter = plainColorVC.self
    drawer.initDrawerViewController(colorsVC, centerViewController: plainColorVC)

    window?.rootViewController = drawer
    
    return true
}
