#implementation AppDelegate
#synthesize viewController = _viewController;
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
navigation = [[UINavigationController alloc] initWithRootViewController:[[ViewController alloc] init]];
self.window.rootViewController = navigation;
//UIWindow *window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// self.window = window;
self.viewController = [[JASidePanelController alloc] init];
self.viewController.shouldDelegateAutorotateToVisiblePanel = NO;
self.viewController.leftPanel = [[LeftViewController alloc] init];
UIViewController *viewcontroller1=[[HomeView alloc]init];
UIViewController *viewcontroller2=[[Speciality alloc]init];
UIViewController *viewcontroller3=[[Activity alloc]init];
UIViewController *viewcontroller4 =[[Notification alloc]init];
UIViewController *viewcontroller5 =[[Profile alloc]init];
viewcontroller1.view.backgroundColor = [UIColor whiteColor];
viewcontroller2.view.backgroundColor = [UIColor whiteColor];
viewcontroller3.view.backgroundColor = [UIColor whiteColor];
viewcontroller4.view.backgroundColor = [UIColor whiteColor];
viewcontroller5.view.backgroundColor = [UIColor whiteColor];
UINavigationController *navcontroller1=[[UINavigationController alloc] initWithRootViewController:viewcontroller1];
UINavigationController *navcontroller2=[[UINavigationController alloc] initWithRootViewController:viewcontroller2];
UINavigationController *navcontroller3=[[UINavigationController alloc] initWithRootViewController:viewcontroller3];
UINavigationController *navcontroller4 =[[UINavigationController alloc] initWithRootViewController:viewcontroller4];
UINavigationController *navcontroller5 =[[UINavigationController alloc] initWithRootViewController:viewcontroller5];
viewcontroller1.title = #"Home";
viewcontroller2.title = #"Speciality";
viewcontroller3.title = #"Activity";
viewcontroller4.title = #"Notification";
viewcontroller5.title = #"Profile";
navcontroller1.tabBarItem.image = [UIImage imageNamed:#"home"];
navcontroller2.tabBarItem.image = [UIImage imageNamed:#"special"];
navcontroller3.tabBarItem.image = [UIImage imageNamed:#"activity"];
navcontroller4.tabBarItem.image = [UIImage imageNamed:#"notify"];
navcontroller5.tabBarItem.image = [UIImage imageNamed:#"Pro"];
self.this = [[UITabBarController alloc] init];
self.this.viewControllers=[NSArray arrayWithObjects:navcontroller1,navcontroller2,navcontroller3,navcontroller4,navcontroller5, nil];
self.this.tabBar.barTintColor = RGBCOLOR(249, 178, 131);
self.viewController.centerPanel = _this;
[self.window makeKeyAndVisible];
return YES;
}

Here, you set the window's root controller to a navigation controller:
self.window.rootViewController = navigation;
And then you go on to instantiate a handful of other nav controllers and add them to a tab controller. It's not clear from your question what you're trying to achieve, but if you want your app to use a tab controller, you'll want to set your window's root controller to the tab controller, not a navigation controller.
