一、UITableBarController（标签栏控制器）中的界面跳转

我是在AppDelegate.m中写的代码，代码如下

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
        self.window = [[UIWindow alloc]initWithFrame:[UIScreen mainScreen].bounds];
    
        //创建标签栏控制器tabBarController
        UITabBarController *tabBarController = [[UITabBarController alloc] init];
    
        //初始化firstView和secondView
        FirstViewController *firstView = [[FirstViewController alloc] init];
        SecondViewController *secondView = [[SecondViewController alloc]init];
    
        //添加子视图控制器firstView和secondView
        [tabBarController addChildViewController:firstView];
        [tabBarController addChildViewController:secondView];
    
        //设置底部标签栏上的title
        firstView.tabBarItem.title = @"first";
        secondView.tabBarItem.title = @"second";
    
        self.window.rootViewController = tabBarController;
        [self.window makeKeyAndVisible];
        return YES;
    }

效果如下：

二、UINavigationController（导航控制器）中的界面跳转

AppDelegate.m中

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
        self.window = [[UIWindow alloc]initWithFrame:[UIScreen mainScreen].bounds];
    
        FirstViewController *firstView = [[FirstViewController alloc] init];
    
        //创建导航控制器
        UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:firstView];
        self.window.rootViewController = nav;
    
        [self.window makeKeyAndVisible];
        return YES;
    }

FirstViewController.m中

- (void)viewDidLoad {
        [super viewDidLoad];
        self.view.backgroundColor = [UIColor whiteColor];
    
        //创建一个Lable标记这是fistView
        UILabel *lable = [[UILabel alloc] initWithFrame:CGRectMake(50, 50, 100, 100)];
        lable.text = @"fist";
        [self.view addSubview:lable];
    
        //创建一个button实现界面间的跳转
        UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    
        button.frame = CGRectMake(50, 150, 150, 100);
    
        [button setTitle:@"To secondView" forState:UIControlStateNormal];
    
        [button addTarget:self action:@selector(buttonPressed) forControlEvents:UIControlEventTouchUpInside];
    
        [self.view addSubview:button];
    }
    
    -(void)buttonPressed
    {
        SecondViewController *secondView = [[SecondViewController alloc] init];
    
        //跳转到secondView的实现方法
        [self.navigationController pushViewController:secondView animated:YES];
    }

UINavigationController中跳转有三个方法，上述例子只实现了一个方法，还有其他两个方法。这里总结一下：

1.[self.navigationController pushViewController:firstView animated:YES];跳转到firstView界面
    2.[self.navigationController popViewControllerAnimated:YES]; //返回上一页面
    3.[self .navigationController popToRootViewControllerAnimated: YES ];  //返回根控制器

三、模态视图  
很简单，就两个方法

[ self presentViewController:SVC animated: YES completion:nil];
    
    [ self dismissViewControllerAnimated: YES completion: nil ];
