在swift中添加没有标签栏控制器的标签栏

我需要在我的视图中添加一个标签栏与标签栏控制器，因为在我的prepareForSegue函数，我将数据传递到包含标签栏我的视图。

我添加了对象库中的标签栏及其项目，并在我的视图类中添加了UITabBarDelegate。 我的代码是这样的：

 class SchedaCompletaVC: UIViewController, UITabBarDelegate { var event:Event! // data passing from prepareforsegue @IBOutlet var mainTabBar:UITabBar! var descrizioneTab:UIViewController! //if i click on first tab, so my default view var mappaTab:UIViewController! // second tab override func viewDidLoad() { super.viewDidLoad() println("event \(event.eventId)") // Do any additional setup after loading the view. } func tabBar(tabBar: UITabBar, didSelectItem item: UITabBarItem!) { switch (item.tag) { case 1: self.view.insertSubview(descrizioneTab.view.belowSubview(mainTabBar)) //here I had error break; case 2: //if second tab is selected break; default: break; } } 

我从一个针对objective-c的教程中得到了这个代码，我试图用swift来转换它。

我的代码不起作用，我不知道该怎么办？

请帮忙。 谢谢！

更新：我的故事板是这样的：

Answer 1

这里是迅捷的版本：

 import UIKit class ViewController: UIViewController, UITabBarDelegate { @IBOutlet weak var mainTabBar: UITabBar! var viewController1: UIViewController? var viewController2: UIViewController? override func viewDidLoad() { super.viewDidLoad() // Do any additional setup after loading the view, typically from a nib. } override func didReceiveMemoryWarning() { super.didReceiveMemoryWarning() // Dispose of any resources that can be recreated. } func tabBar(tabBar: UITabBar, didSelectItem item: UITabBarItem!) { switch item.tag { case 1: if viewController1 == nil { var storyboard = UIStoryboard(name: "Main", bundle: nil) viewController1 = storyboard.instantiateViewControllerWithIdentifier("ViewController1") as! ViewController1 } self.view.insertSubview(viewController1!.view!, belowSubview: self.mainTabBar) break case 2: if viewController2 == nil { var storyboard = UIStoryboard(name: "Main", bundle: nil) viewController2 = storyboard.instantiateViewControllerWithIdentifier("ViewController2") as! ViewController2 } self.view.insertSubview(viewController2!.view!, belowSubview: self.mainTabBar) break default: break } } } 

然后，你应该点击UITabBarItem＆ctrl拖动它到viewcontroller并点击委托。

标签栏项目的标签（对于第一个标签项目标签是1，对于第二个标签项目，标签是2）

ViewController的StoryBoard标识符（ViewController1和ViewController2分别）

Answer 2

我只有一个Objective-C解决scheme。 它工作正常; 也许你可以把它转换成Swift。

ViewController.h文件代码

  #import <UIKit/UIKit.h> @interface ViewController : UIViewController<UITabBarDelegate> @property (weak, nonatomic) IBOutlet UITabBar *mainTabBar; @end 

ViewController.m文件

  #import "ViewController.h" #import "MyFirstTabViewController.h" #import "MySecondTabViewController.h" @interface ViewController () { UIViewController *viewController1; UIViewController *viewController2; } @end @implementation ViewController - (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view, typically from a nib. self.mainTabBar.delegate=self; } - (void)tabBar:(UITabBar *)tabBar didSelectItem:(UITabBarItem *)item { switch (item.tag) { case 1: if (viewController1 == nil) { viewController1 = [[UIStoryboard storyboardWithName:@"Main" bundle:NULL] instantiateViewControllerWithIdentifier:@"First"]; } [self.view insertSubview:viewController1.view belowSubview:self.mainTabBar]; break; case 2: if (viewController2 == nil) { viewController2 = [[UIStoryboard storyboardWithName:@"Main" bundle:NULL] instantiateViewControllerWithIdentifier:@"Second"]; } [self.view insertSubview:viewController2.view belowSubview:self.mainTabBar]; break; default: break; } } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; // Dispose of any resources that can be recreated. } @end 

不要忘记。

1）标签栏项目的标签（对于第一个标签项目标签是1，对于第二个标签项目，标签是2）

2）ViewController的StoryBoard标识符（分别为第一和第二）
