最近在自学Swift，想要写一个纯代码封装常用TabBar基本框架，可是网上查了好多资料发现大家都是跟Xib结合使用的，本人对Xib不是特别擅长，所以想实现一款纯代码封装常用TabBar基本框架。
不说废话，上代码

import UIKit
class TabeBarViewController: UITabBarController {
var tabBarBgImg:UIImageView?
var tabBarBgImgSelected:UIImageView?
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
/*
* 更改tabBar选中按钮的颜色
*/
// self.tabBar.tintColor = UIColor.redColor()
self.setUpAllChildViewController()
}
func setUpAllChildViewController() {
self.setUpOneChildViewController(MainViewController(), image: UIImage.init(named: "main_off")!, selectedImage: UIImage.init(named: "main_on")!, title: "下厨房")
self.setUpOneChildViewController(MarketViewController(), image: UIImage.init(named: "market_off")!, selectedImage: UIImage.init(named: "market_on")!, title: "市集")
self.setUpOneChildViewController(CommunityVC(), image: UIImage.init(named: "community_off")!, selectedImage: UIImage.init(named: "community_on")!, title: "社区")
self.setUpOneChildViewController(MeViewController(), image: UIImage.init(named: "me_off")!, selectedImage: UIImage.init(named: "me_on")!, title: "我")
}
func setUpOneChildViewController(viewController: UIViewController, image: UIImage, selectedImage: UIImage, title: NSString) {
let navVC = UINavigationController.init(rootViewController: viewController)
// 让图片显示图片原始颜色 “UIImage” 后+ “.imageWithRenderingMode(.AlwaysOriginal)”
navVC.tabBarItem = UITabBarItem.init(title: title as String, image: image, selectedImage: selectedImage.imageWithRenderingMode(.AlwaysOriginal))
self.addChildViewController(navVC)
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
/*
// MARK: - Navigation
// In a storyboard-based application, you will often want to do a little preparation before navigation
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
// Get the new view controller using segue.destinationViewController.
// Pass the selected object to the new view controller.
}
*/
}
Appdelegate里面代码
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Override point for customization after application launch.
//设置tabbar
self.window = UIWindow(frame: UIScreen.mainScreen().bounds)
self.window?.backgroundColor = UIColor.whiteColor()
//初始化tabbar
let tabbarVC = TabeBarViewController()
self.window!.rootViewController = tabbarVC
self.window!.makeKeyAndVisible()
return true
}
