［背景］
发现自带的，都不是我想要的。
连官网都是：
Start Developing iOS Apps (Swift): Build a Basic UI
基于界面工具的。
［解决过程］
1.搜：
swift programmatically create new project tab page
参考：
2.搜：
swift programmatically create Tabbar
最后暂时是：
AppDelegate.swift
相关代码：
import UIKit
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Override point for customization after application launch.
//application.statusBarHidden = true;
//init main view controller
let mainViewVC = MainViewController()
let navigation = UINavigationController(rootViewController:mainViewVC)
navigation.view.layer.shadowOffset = CGSizeMake(0,0);
navigation.view.layer.shadowOpacity = 0.5;
navigation.view.layer.shadowRadius = 10.0;
navigation.view.layer.shadowColor = UIColor.blackColor().CGColor
self.window!.rootViewController = mainViewVC
return true
}MainViewController.swift

import UIKit
class MainViewController: UITabBarController {
var titleLabel:UILabel!
let mainTabs = ["消息", "通讯录", "文档", "个人中心"]
override func viewDidLoad() {
super.viewDidLoad()
NSLog("MainViewController viewDidLoad()")
self.view.backgroundColor = UIColor.whiteColor()
let tabbgView = UIView()
tabbgView.frame = CGRectMake(0, 20, CGRectGetWidth(self.view.bounds), 44)
//tabbgView.backgroundColor = UIColor(hexString: "#ff3333", alpha: 0.85)
tabbgView.backgroundColor = UIColor.blackColor()
self.view.addSubview(tabbgView)
let statusView = UIView()
statusView.frame = CGRectMake(0, 0, CGRectGetWidth(self.view.bounds), 20)
//statusView.backgroundColor = UIColor(hexString: "#ff3333")
statusView.backgroundColor = UIColor.lightGrayColor()
self.view.addSubview(statusView)
let addMenu = UIImage(named:"add_white_24x24.png");
let addButton = UIButton()
addButton.frame = CGRectMake(self.view.bounds.width - 54, 0, 44.0, 44.0)
addButton.addTarget(self, action:"showAddMenu:", forControlEvents:UIControlEvents.TouchUpInside)
addButton.setImage(addMenu,forState:UIControlState.Normal)
tabbgView.addSubview(addButton)
let searchMenu = UIImage(named:"search_24x24.png");
let searchButton = UIButton()
searchButton.frame = CGRectMake(addButton.frame.origin.x - 44, 0, 44.0, 44.0)
searchButton.addTarget(self, action:"jumpToSearch:", forControlEvents:UIControlEvents.TouchUpInside)
searchButton.setImage(searchMenu,forState:UIControlState.Normal)
tabbgView.addSubview(searchButton)
titleLabel = UILabel(frame: CGRectMake(20, 20, self.view.bounds.width - 108, 44.0))
titleLabel.textColor = UIColor.whiteColor()
titleLabel.textAlignment = NSTextAlignment.Left
titleLabel.font = UIFont.boldSystemFontOfSize(18)
titleLabel.text = STR_APP_NAME
self.view.addSubview(titleLabel)
//create tabs
let viewMessage = MessageViewController()
let viewContact = ContactViewController()
let viewFile = FileViewController()
let viewPersonalCenter = PersonalCenterViewController()
let nvcMessage = UINavigationController(rootViewController: viewMessage)
nvcMessage.tabBarItem = UITabBarItem(title: mainTabs[0], image: UIImage(named:"message.png"), tag:0);
let nvcContact = UINavigationController(rootViewController: viewContact)
nvcContact.tabBarItem = UITabBarItem(title: mainTabs[1], image: UIImage(named:"contact.png"), tag:1);
let nvcFile = UINavigationController(rootViewController: viewFile)
nvcFile.tabBarItem = UITabBarItem(title: mainTabs[2], image: UIImage(named:"file.png"), tag:2);
let nvcPersonalCenter = UINavigationController(rootViewController: viewPersonalCenter)
nvcPersonalCenter.tabBarItem = UITabBarItem(title: mainTabs[3], image: UIImage(named:"peronal_center.png"), tag:3);
self.viewControllers = [nvcMessage, nvcContact, nvcFile, nvcPersonalCenter]
//default select message index 0
self.selectedIndex = 0
}
//show add menu
func showAddMenu(button : UIButton){
}
//jump to search view
func jumpToSearch(button : UIButton){
}
}其他的，比如：
MessageViewController.swift
都是空的：
import UIKit
class MessageViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
}
}效果是：
此处还是没有tab图片的。
需要去找一下。
经过一番折腾，代码如下：
AppDelegate.swift
相关代码：
import UIKit
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Override point for customization after application launch.
//application.statusBarHidden = true;
//init main view controller
let mainViewVC = MainViewController()
let navigation = UINavigationController(rootViewController:mainViewVC)
navigation.view.layer.shadowOffset = CGSizeMake(0,0);
navigation.view.layer.shadowOpacity = 0.5;
navigation.view.layer.shadowRadius = 10.0;
navigation.view.layer.shadowColor = UIColor.blackColor().CGColor
self.window!.rootViewController = mainViewVC
return true
}MainViewController.swift代码：

}最后效果为：
