iPhone开发 tabBarController与UINavigationController结合

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

{

    self.window = [[UIWindowalloc] initWithFrame:[[UIScreenmainScreen] bounds]];

    self.window.backgroundColor = [UIColorwhiteColor];

    

    //生成各个视图控制器

    MedicalData* aa = [[MedicalDataalloc]init];

    UINavigationController *aaNav = [[UINavigationControlleralloc] initWithRootViewController:aa];

    CarePrescription* dd = [[CarePrescriptionalloc]init];

    UINavigationController *ddNav = [[UINavigationControlleralloc] initWithRootViewController:dd];

    //加入一个数组    

    NSArray* controllerArray = [[NSArray alloc]initWithObjects:aaNav,bbNav,ccNav,ddNav ,nil];

    //创建UITabBarController控制器  (定义在.h中，否在开启arc会自动释放掉，内存访问出错)

    tabBarController = [[UITabBarControlleralloc]init];

    //设置委托

    tabBarController.delegate = self;

    //设置UITabBarController控制器的viewControllers属性为我们之前生成的数组controllerArray

    tabBarController.viewControllers = controllerArray;

    //默认选择第1个视图选项卡（索引从0开始的）

    tabBarController.selectedIndex = 0;

    //设置TabBarItem的标题与图片//30 * 30
