1.删除系统自己给我们的main.board。和viewCollorer.h/.m文件，info.plist删除main

2.appDelegate.m

//手动创建window

self.window = [[UIWindow alloc]initWithFrame:[UIScreen mainScreen].bounds];

self.window.backgroundColor = [UIColor whiteColor];

//创建导航控制器

UINavigationController *naviga = [[UINavigationController alloc]initWithRootViewController:[[MYViewController alloc]init]];

//设置下面导航条图片

naviga.tabBarItem.image = [UIImage imageNamed:@"tab1.png"];

//创建标签控制器(width:49)

UITabBarController *MytabBar = [[UITabBarController alloc]init];

//添加到MytabBar

MytabBar.viewControllers = @[naviga,twoNavi,threeNavi];

//为了让他能启动加载这个window

[self.window makeKeyAndVisible];

3.创建导航右边和左边的按钮

首先定义按钮（系统自定义）

//创建右边按钮

UIBarButtonItem *btnGO = [[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(ClickedItem:)];

//自定义按钮用自定义按钮方法

UIBarButtonItem *btnUP = [[UIBarButtonItem alloc]initWithTitle:@"编辑" style:UIBarButtonItemStylePlain target:self action:@selector(ClickedItem:)];

//自定义设置导航默认的返回按钮

self.navigationItem.backBarButtonItem = [[UIBarButtonItem alloc]initWithTitle:@"返回" style:UIBarButtonItemStylePlain target:self action:nil];

//改变图片返回按钮

[self.navigationController.navigationBar setBackIndicatorImage:[UIImage imageNamed:@"back_btn.png"]];

[self.navigationController.navigationBar setBackIndicatorTransitionMaskImage:[UIImage imageNamed:@"back_btn.png"]];

//自动以颜色按钮

[self.navigationController.navigationBar setTintColor:[UIColor purpleColor]];

//设置导航条按钮

[self.navigationController.navigationBar setBarTintColor:[UIColor orangeColor]];

//设置字体大小

[self.navigationController.navigationBar setTitleTextAttributes:@{NSFontAttributeName:[UIFont systemFontOfSize:25],NSForegroundColorAttributeName:[UIColor blueColor]}];

4.使用导航页面跳转

SecondViewController *twoView = [[SecondViewController alloc]init];

//页面跳转

[self.navigationController pushViewController:twoView animated:YES];

5.页面回跳

//返回到最主页,弹出当前控制器，或者跳到指定页面

[self.navigationController popToRootViewControllerAnimated:YES];
