iPhone開發 tabBarController與UINavigationController結合

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window = [[UIWindowalloc] initWithFrame:[[UIScreenmainScreen] bounds]];
    self.window.backgroundColor = [UIColorwhiteColor];
   
    //產生各個視圖控制器
    MedicalData* aa = [[MedicalDataalloc]init];
    UINavigationController *aaNav = [[UINavigationControlleralloc] initWithRootViewController:aa];
    HealthRecord* bb = [[HealthRecordalloc]init];
    UINavigationController *bbNav = [[UINavigationControlleralloc] initWithRootViewController:bb];

    UINavigationController *ccNav = [[UINavigationControlleralloc] initWithRootViewController:cc];
    CarePrescription* dd = [[CarePrescriptionalloc]init];
    UINavigationController *ddNav = [[UINavigationControlleralloc] initWithRootViewController:dd];
    //加入一個數組   
    NSArray* controllerArray = [[NSArray alloc]initWithObjects:aaNav,bbNav,ccNav,ddNav ,nil];
    //建立UITabBarController控制器  (定義在.h中，否在開啟arc會自動釋放掉，記憶體訪問出錯)
    tabBarController = [[UITabBarControlleralloc]init];
    //設定委託www.2cto.com
    tabBarController.delegate = self;
    //設定UITabBarController控制器的viewControllers屬性為我們之前產生的數組controllerArray
    tabBarController.viewControllers = controllerArray;
    //預設選擇第1個視圖選項卡（索引從0開始的）
    tabBarController.selectedIndex = 0;
    //設定TabBarItem的標題與圖片//30 * 30
    [(UITabBarItem *)[tabBarController.tabBar.itemsobjectAtIndex:0] setTitle:@"體檢資料"]; 
    [(UITabBarItem *)[tabBarController.tabBar.itemsobjectAtIndex:0] setImage:[UIImageimageNamed:@"check_no.png"]];

    [(UITabBarItem *)[tabBarController.tabBar.itemsobjectAtIndex:2] setImage:[UIImageimageNamed:@"ckb1.png"]];
    [(UITabBarItem *)[tabBarController.tabBar.itemsobjectAtIndex:3] setTitle:@"保健處方"];

    //讀取
    UIViewController* activeController = tabBarController.selectedViewController;
    if(activeController == aa){
        //
    }
    //把tabBarController的view作為子視圖添加到window
    [self.windowaddSubview:tabBarController.view];
    [self.windowmakeKeyAndVisible];
    returnYES;
 
}
//切換事件
- (void)tabBarController:(UITabBar *)tb  didSelectViewController:(UIViewController *__strong)viewController
{
    NSLog(viewController.title);
    if([viewController.title isEqualToString:@"保健處方"])
    {
        [(UITabBarItem *)[tabBarController.tabBar.itemsobjectAtIndex:3] setBadgeValue:nil];
        //[(UITabBarItem *)[tabBarController.tabBar.items objectAtIndex:3] setBadgeValue:@"0"];
    }
