使用两个或多个tabbar在swift中创建Tabbarbase应用程序

我正在创建tabbar基本应用程序。。但是我不能像Objective-C那样将第二个viewcontroller导入到AppDelegate文件中。有人能帮我吗

我试过像这样进口 导入UIKit 导入第二个vc.swift

---

但是它会给我一个错误：没有像SecondVC.swift这样的模块。最后，我可以用两个或更多的

viewController

创建

TabBar

我只是犯了一个错误，在swift中创建了一个新文件

import UIKit<br>
@UIApplicationMain<br>
class AppDelegate: UIResponder, UIApplicationDelegate {

var window: UIWindow?


func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool
{
    var tabbar = UITabBarController()
    let storyboard = UIStoryboard(name: "Main", bundle: nil)

    let HomeVC : ViewController = storyboard.instantiateViewControllerWithIdentifier("HomeVC") as ViewController
    HomeVC.tabBarItem.title = "Home"
    HomeVC.tabBarItem.image = UIImage(named: "home.png")

    let SettingVC : SettingViewController = storyboard.instantiateViewControllerWithIdentifier("SettingVC") as SettingViewController
    SettingVC.tabBarItem.title = "Setting"
    SettingVC.tabBarItem.image = UIImage(named: "settings.png")

    var arrayTabbar = [HomeVC,SettingVC]

    tabbar.viewControllers = arrayTabbar
    tabbar.view.autoresizingMask = UIViewAutoresizing.FlexibleWidth | UIViewAutoresizing.FlexibleHeight
    window?.rootViewController = tabbar
    window?.makeKeyAndVisible()
    return true
}

我们必须使用cocoTouch类创建一个新文件，但我正在使用Swift文件创建

是的，我们不能像Objective-C那样导入新的ViewController。我们必须使这些ViewController的对象成为对象

下面是我在swift中创建TabBar基本应用程序的appDelegate文件代码

import UIKit<br>
@UIApplicationMain<br>
class AppDelegate: UIResponder, UIApplicationDelegate {

var window: UIWindow?


func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool
{
    var tabbar = UITabBarController()
    let storyboard = UIStoryboard(name: "Main", bundle: nil)

    let HomeVC : ViewController = storyboard.instantiateViewControllerWithIdentifier("HomeVC") as ViewController
    HomeVC.tabBarItem.title = "Home"
    HomeVC.tabBarItem.image = UIImage(named: "home.png")

    let SettingVC : SettingViewController = storyboard.instantiateViewControllerWithIdentifier("SettingVC") as SettingViewController
    SettingVC.tabBarItem.title = "Setting"
    SettingVC.tabBarItem.image = UIImage(named: "settings.png")

    var arrayTabbar = [HomeVC,SettingVC]

    tabbar.viewControllers = arrayTabbar
    tabbar.view.autoresizingMask = UIViewAutoresizing.FlexibleWidth | UIViewAutoresizing.FlexibleHeight
    window?.rootViewController = tabbar
    window?.makeKeyAndVisible()
    return true
}

导入UIKit

@UIApplicationMain

类AppDelegate:UIResponder、UIApplicationLegate{
变量窗口：UIWindow？
func应用程序（应用程序：UIApplication，didFinishLaunchingWithOptions启动选项：[NSObject:AnyObject]？）->Bool
{
var tabbar=UITabBarController（）
let storyboard=UIStoryboard（名称：“Main”，捆绑包：nil）
让HomeVC:ViewController=storyboard.instanceeviewcontrollerwhiteIdentifier（“HomeVC”）作为ViewController
HomeVC.tabBarItem.title=“主页”
HomeVC.tabBarItem.image=UIImage（名为：“home.png”）
让SettingVC:SettingViewController=storyboard.InstanceEviewController标识符（“SettingVC”）作为SettingViewController
设置vc.tabBarItem.title=“设置”
SettingVC.tabBarItem.image=UIImage（名为：“settings.png”）
var arrayTabbar=[HomeVC，SettingVC]
tabbar.viewControllers=ArrayTabar
tabbar.view.autoresizingMask=uiviewsautoresizing.FlexibleWidth | uiviewsautoresizing.FlexibleHeight
窗口？.rootViewController=选项卡栏
窗口？.makeKeyAndVisible（）
返回真值
}
