APP快速搭建框架

AppDelegate:

 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
     // Override point for customization after application launch.
     //1.创建窗口
     self.window = [[UIWindow alloc]initWithFrame:[UIScreen mainScreen].bounds];
     //设置窗口的根控制器
     CYXTabBarController *tabBarVC = [[CYXTabBarController alloc]init];
     self.window.rootViewController = tabBarVC;
     //3.显示窗口
     [self.window makeKeyAndVisible];
     return YES;
 }

CYXTabBarController:

@interface CYXTabBarController : UITabBarController

 - (void)viewDidLoad {
     [super viewDidLoad];
     // Do any additional setup after loading the view.VC

     //添加第一个控制器
     //1.1 初始化
     CYXOneViewController *oneVC = [[CYXOneViewController alloc]init];
     //1.2 把oneVC添加为UINavigationController的根控制器
     UINavigationController *nav1 = [[UINavigationController alloc]initWithRootViewController:oneVC];
     //设置tabBar的标题
     nav1.title = @"首页";
     //设置导航栏背景颜色
     nav1.navigationBar.barTintColor = [UIColor yellowColor];
     //设置tabBar的图标
     nav1.tabBarItem.image = [UIImage imageNamed:@"icon_tabbar_merchant_normal"];
     //设置navigationBar的标题
     oneVC.navigationItem.title = @"这是导航栏标题1";
     //设置背景色
     oneVC.view.backgroundColor = [UIColor whiteColor];
     //1.3 把UINavigationController交给UITabBarController管理
     [self addChildViewController:nav1];

     //添加第二个控制器
     CYXTwoViewController *twoVC = [[CYXTwoViewController alloc]init];
     UINavigationController *nav2 = [[UINavigationController alloc]initWithRootViewController:twoVC];
     nav2.title = @"我的";
     //设置导航栏背景图片
     //[nav2.navigationBar setBackgroundImage:[UIImage imageNamed:@""] forBarMetrics:UIBarMetricsDefault];
     nav2.tabBarItem.image = [UIImage imageNamed:@"icon_tabbar_mine"];
     twoVC.navigationItem.title = @"这是导航栏标题2";
     twoVC.view.backgroundColor = [UIColor whiteColor];
     [self addChildViewController:nav2];

     //添加第三个控制器
     CYXThreeViewController *threeVC = [[CYXThreeViewController alloc]init];
     UINavigationController *nav3 = [[UINavigationController alloc]initWithRootViewController:threeVC];
     nav3.title = @"开门";
     nav3.tabBarItem.image = [UIImage imageNamed:@"icon_tabbar_onsite"];
     threeVC.navigationItem.title = @"这是导航栏标题3";
     threeVC.view.backgroundColor = [UIColor whiteColor];
     [self addChildViewController:nav3];

     //添加第四个控制器
     CYXFourViewController *fourVC = [[CYXFourViewController alloc]init];
     UINavigationController *nav4 = [[UINavigationController alloc]initWithRootViewController:fourVC];
     nav4.title = @"更多";
     nav4.tabBarItem.image = [UIImage imageNamed:@"icon_tabbar_misc"];
     fourVC.navigationItem.title = @"这是导航栏标题4";
     fourVC.view.backgroundColor = [UIColor whiteColor];
     [self addChildViewController:nav4];
