swift-UINavigationController純程式碼自訂導航控制器及底部工具列的使用，ledcontroller控制器

step1：自訂一個類  NTViewController，該類繼承UITabBarController：

////  NTViewController.swift//  Housekeeper////  Created by 盧洋 on 15/10/20.//  Copyright © 2015年 奈文摩爾. All rights reserved.//import Foundationimport UIKitclass NTViewController:UITabBarController{       var items=[];    //頁面初始化    override func viewDidLoad() {        super.viewDidLoad();        //1.建立首頁導航控制器        let vwIndex=index();        let navIndex=UINavigationController(rootViewController: vwIndex);        navIndex.title="首頁";
　　　　　//設定工具列預設顯示的圖片        navIndex.tabBarItem.image=UIImage(named: "home")?.imageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal);
　　　　　//設定工具列選中後的圖片        navIndex.tabBarItem.selectedImage=UIImage(named: "homes.png")?.imageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal);                        //2.建立活動資訊導航控制器        let vwActivityInfo=activityInfo();        let navActivityInfo=UINavigationController(rootViewController: vwActivityInfo);        navActivityInfo.title="活動資訊";        navActivityInfo.tabBarItem.image=UIImage(named: "Activity-information.png")?.imageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal);        navActivityInfo.tabBarItem.selectedImage=UIImage(named: "Activity-informations.png")?.imageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal);                        //3.建立車輛展示導航控制器        let vwCarDisplay=carDisplay();        let navCarDisplay=UINavigationController(rootViewController: vwCarDisplay);        navCarDisplay.title="車輛展示";        navCarDisplay.tabBarItem.image=UIImage(named: "Vehicle-display.png")?.imageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal);        navCarDisplay.tabBarItem.selectedImage=UIImage(named: "Vehicle-displays.png")?.imageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal);                //4.建立個人中心導航控制器        let vwPersonalCenter=personalCenter();        let navPersonalCenter=UINavigationController(rootViewController: vwPersonalCenter);        navPersonalCenter.title="個人中心";        navPersonalCenter.tabBarItem.image=UIImage(named: "Personal-Center.png")?.imageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal);        navPersonalCenter.tabBarItem.selectedImage=UIImage(named: "Personal-Centers.png")?.imageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal);                //5.添加到工具列         items=[navIndex,navActivityInfo,navCarDisplay,navPersonalCenter];        self.viewControllers=items as? [UIViewController];        self.navigationController?.navigationBar.tintColor=UIColor.whiteColor();                //6.自訂工具列        self.tabBar.backgroundColor=UIColor.clearColor();        //底部工具列背景顏色        self.tabBar.barTintColor=UIColor.appMainColor();                //7.設定底部工具列文字顏色（預設狀態和選中狀態）        UITabBarItem.appearance().setTitleTextAttributes(NSDictionary(object:UIColor.whiteColor(), forKey:NSForegroundColorAttributeName) as? [String : AnyObject], forState:UIControlState.Normal);        UITabBarItem.appearance().setTitleTextAttributes(NSDictionary(object:UIColor.blueWithTabbar(), forKey:NSForegroundColorAttributeName) as? [String : AnyObject], forState:UIControlState.Selected)            }}

step2:開啟 AppDelegate.swift

////  AppDelegate.swift//  Housekeeper////  Created by 盧洋 on 15/10/14.//  Copyright © 2015年 奈文摩爾. All rights reserved.//import Foundationimport UIKit@UIApplicationMainclass AppDelegate: UIResponder, UIApplicationDelegate {    var window: UIWindow?    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {        // 應用程式啟動後        //1.聲明一個空視圖        self.window = UIWindow(frame: UIScreen.mainScreen().bounds);        self.window!.backgroundColor=UIColor.whiteColor();                //2.1導航背景顏色        UINavigationBar.appearance().barTintColor=UIColor.appMainColor();                UIBarButtonItem.appearance().setBackButtonTitlePositionAdjustment(UIOffsetMake(CGFloat(NSInteger.min),CGFloat(NSInteger.min)), forBarMetrics:UIBarMetrics.Default);        //2.2導航標題文字顏色        UINavigationBar.appearance().titleTextAttributes=NSDictionary(object:UIColor.whiteColor(), forKey:NSForegroundColorAttributeName) as? [String : AnyObject];        
　　　　　//樓主的狀態列顏色改變了，設定為了白色，如果有需要，開啟 info.plist  增加Key（View controller-based status bar appearance，Value為 no        //2.3將狀態列變為白色        UIApplication.sharedApplication().statusBarStyle = UIStatusBarStyle.LightContent;                //2.4設定返回按鈕顏色        UINavigationBar.appearance().tintColor=UIColor.whiteColor();               //3.指定根視圖        let rootView=NTViewController();        self.window!.rootViewController=rootView;        self.window!.makeKeyAndVisible();                       return true    }    func applicationWillResignActive(application: UIApplication) {        // Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.        // Use this method to pause ongoing tasks, disable timers, and throttle down OpenGL ES frame rates. Games should use this method to pause the game.    }    func applicationDidEnterBackground(application: UIApplication) {        // Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later.        // If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.    }    func applicationWillEnterForeground(application: UIApplication) {        // Called as part of the transition from the background to the inactive state; here you can undo many of the changes made on entering the background.    }    func applicationDidBecomeActive(application: UIApplication) {        // Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.    }    func applicationWillTerminate(application: UIApplication) {        // Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.    }}
