Navigation + Tab Bar 常用组合框架

        

看到很多项目中都采用的是Navigation加Tab Bar组合到一起，完成视图切换操作，在导航栏上添加基本按钮，给予响应时间，让应用给用户更好的体验，所以本菜鸟写了这个这样一个Demo，仅供学习

所创建工程模板是最后一个 Empty Application

      

先看运行效果:

第一个视图，点击按钮切换视图，点击导航栏上按钮可以切换回去

     

第二个视图设置了背景颜色和透明度  第三个视图添加了背景图片

    

第四个视图，在导航栏上添加了两个按钮，左边按钮属于自定义标题，右边按钮是系统的图标，点击左按钮弹出一个警告，右边按钮没有添加响应事件，点击后没反应

     

Tab Bar上添加的都是自定义图片

框架组合的主要代码，在AppDelegate.m中

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {     self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];     // Override point for customization after application launch.     self.window.backgroundColor = [UIColor whiteColor];          _tabBarController = [[UITabBarController alloc] init];     _tabBarController.delegate = self;           FirstViewController *firstViewController = [[FirstViewController alloc] initWithNibName:@"FirstViewController" bundle:nil];          SecondViewController *secondViewController = [[SecondViewController alloc] initWithNibName:@"secondViewController" bundle:nil];          ThirdViewController *thirdViewController = [[ThirdViewController alloc] initWithNibName:@"ThirdViewController" bundle:nil];          FourViewController *fourViewController = [[FourViewController alloc] initWithNibName:@"FourViewController" bundle:nil];          UINavigationController *navFirst = [[UINavigationController alloc] initWithRootViewController:firstViewController]; //    在加载图片是把标题都覆盖了，所以运行效果并没有显示这些文字     navFirst.title = @"第一个视图";          UINavigationController *navSecond = [[UINavigationController alloc] initWithRootViewController:secondViewController];     navSecond.title = @"第二个视图";          UINavigationController *navThird = [[UINavigationController alloc] initWithRootViewController:thirdViewController];     navThird.title = @"第三个视图";          UINavigationController *navFour = [[UINavigationController alloc] initWithRootViewController:fourViewController];     navFour.title = @"第四个视图";               _tabBarController.viewControllers = [NSArray arrayWithObjects:navFirst,navSecond,navThird,navFour, nil];     _window.rootViewController = _tabBarController;          [self.window addSubview:firstViewController.view];     [self.window makeKeyAndVisible];     return YES; } 

第一个视图切换按钮响应事件

- (IBAction)switchView:(id)sender {          FirstViewController *firstController = [[FirstViewController alloc] init];     [self.navigationController pushViewController:firstController animated:YES];     firstController.title = @"第一个视图另一个视图"; } 

第四个视图添加两个按钮方法，在最后一个控制机的.m文件中的-(void)viewDidLoad方法中

- (void)viewDidLoad {     [super viewDidLoad]; 	// Do any additional setup after loading the view.     UIBarButtonItem *leftButton = [[UIBarButtonItem alloc] initWithTitle:@"测试"                                                                    style:UIBarButtonItemStylePlain target:self                                                                   action:@selector(pullWarn)];     self.navigationItem.leftBarButtonItem = leftButton;          UIBarButtonItem *rightButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCamera target:self action:nil];     self.navigationItem.rightBarButtonItem = rightButton; }
