【swift】UITabBarControllerひな型

これも毎回過去のコードをみてるのでひな型をメモしておきます。
UITabBarController配下にUINavigtionControllerを配置する形です。

AppDelegate.swift

class AppDelegate: UIResponder, UIApplicationDelegate {
    ・・・
    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
        let tabbarController: TabbarController = TabbarController()
        self.window = UIWindow(frame: UIScreen.mainScreen().bounds)
        self.window?.rootViewController = tabbarController
        self.window?.makeKeyAndVisible()
        return true
    }
}

TabbarController.swift

class TabbarController: UITabBarController {
    
    var navController: UINavigationController!
    var navController2: UINavigationController!
    var navController3: UINavigationController!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // ViewController作成
        let vc = UIViewController()
        vc.view.backgroundColor = UIColor.whiteColor()
        vc.navigationItem.title = "ナビ1"
        navController = UINavigationController(rootViewController: vc)
        
        let vc2 = UIViewController()
        vc2.view.backgroundColor = UIColor.whiteColor()
        vc2.navigationItem.title = "ナビ2"
        navController2 = UINavigationController(rootViewController: vc2)
        
        let vc3 = UIViewController()
        vc3.view.backgroundColor = UIColor.whiteColor()
        vc3.navigationItem.title = "ナビ3"
        navController3 = UINavigationController(rootViewController: vc3)
        
        // タブバーの色設定
        UITabBar.appearance().tintColor = UIColor.blackColor()
        UITabBar.appearance().barTintColor = UIColor.whiteColor()
        
        // タブ画像設定
        navController.tabBarItem.image = UIImage(named: "tab.png")
        navController2.tabBarItem.image = UIImage(named: "tab2.png")
        navController3.tabBarItem.image = UIImage(named: "tab3.png")
        
        // タブタイトル設定
        navController.tabBarItem.title = "タブ1"
        navController2.tabBarItem.title = "タブ2"
        navController3.tabBarItem.title = "タブ3"
        
        let tabs = NSArray(objects: navController, navController2, navController3)
        self.setViewControllers(tabs as! [UINavigationController], animated: true)
    }
}

ここではViewControllerを直接書いてますが、別ファイルにするのが一般的ですね
以上です
