#import "WPTabBarController.h"#import "WPFirstViewController.h"#import "WPSecondViewController.h"#import "WPThirdViewController.h"#import "WPFourthViewController.h"@interface WPTabBarController ()@end@implementation WPTabBarController- (void)viewDidLoad {    WPFirstViewController *firsVc=[[WPFirstViewController alloc]init];    WPSecondViewController *secondVc=[[WPSecondViewController alloc]init];    WPThirdViewController *thirdVc=[[WPThirdViewController alloc]init];    WPFourthViewController *fourthVc=[[WPFourthViewController alloc]init];        //以下两种方式均可设置tabbar上得标题    firsVc.tabBarItem.title=@"消息";    //firsVc.title=@"消息";    secondVc.tabBarItem.title=@"联系人";    //secondVc.title=@"联系人";    thirdVc.tabBarItem.title=@"动态";    //thirdVc.title=@"动态";    fourthVc.tabBarItem.title=@"设置";    //fourthVc.title=@"设置";    //设置icon    firsVc.tabBarItem.image=[UIImage imageNamed:@"tab_recent_nor"];    secondVc.tabBarItem.image=[UIImage imageNamed:@"tab_buddy_nor"];    thirdVc.tabBarItem.image=[UIImage imageNamed:@"tab_qworld_nor"];    fourthVc.tabBarItem.image=[UIImage imageNamed:@"tab_me_nor"];        firsVc.view.backgroundColor=[UIColor redColor];    secondVc.view.backgroundColor=[UIColor whiteColor];    thirdVc.view.backgroundColor=[UIColor purpleColor];    fourthVc.view.backgroundColor=[UIColor greenColor];            //用以下方式添加子控制器    //self.viewControllers=@[firsVc,secondVc,thirdVc,fourthVc];    [self addChildViewController:firsVc];    [self addChildViewController:secondVc];    [self addChildViewController:thirdVc];    [self addChildViewController:fourthVc];        [super viewDidLoad];    // Do any additional setup after loading the view.}

核心：

——定义1个tabBat控制器和4个导航控制器，然后通过addChildViewController或者数组的形式把4个导航控制器加到tabBar控制器中。

——每个导航控制器通过tabBarItem属性来设置标题和icon等。
