    <p>I am using <code>UITabBarController</code> on a view controller i.e <code>launchviewcontroller</code> which contains code on <code>loadview</code> as below:</p> <pre><code>- (void)loadView { viewControllers=[[NSMutableArray alloc]initWithCapacity:2]; tabBarController=[[UITabBarController alloc]init]; MyProfileViewController *view1=[[MyProfileViewController alloc]init]; localNavigationController=[[UINavigationController alloc]initWithRootViewController:view1]; localNavigationController.navigationBar.alpha=1.0; // localNavigationController.navigationBar.tintColor=[UIColor colorWithRed:0.65 green:0.84 blue:0.88 alpha:1]; localNavigationController.navigationBar.tintColor=[UIColor blackColor]; // localNavigationController.navigationBar. [viewControllers addObject:localNavigationController]; [view1 release]; [localNavigationController release]; localNavigationController=nil; TodaysPicksViewController *view2=[[TodaysPicksViewController alloc]initWithLeagueType:@"CFL Football"]; localNavigationController=[[UINavigationController alloc]initWithRootViewController:view2]; localNavigationController.navigationBar.alpha=1.0; localNavigationController.navigationBar.tintColor=[UIColor blackColor]; [viewControllers addObject:localNavigationController]; [view2 release]; [localNavigationController release]; localNavigationController=nil; Rules_PoliciesViewController *view3=[[Rules_PoliciesViewController alloc]init]; localNavigationController=[[UINavigationController alloc]initWithRootViewController:view3]; localNavigationController.navigationBar.alpha=1.0; localNavigationController.navigationBar.tintColor=[UIColor blackColor]; [viewControllers addObject:localNavigationController]; [view3 release]; [localNavigationController release]; localNavigationController=nil; LogoutViewController *view4=[[LogoutViewController alloc]init]; localNavigationController=[[UINavigationController alloc]initWithRootViewController:view4]; localNavigationController.navigationBar.alpha=1.0; localNavigationController.navigationBar.tintColor=[UIColor blackColor]; [viewControllers addObject:localNavigationController]; [view4 release]; [localNavigationController release]; localNavigationController=nil; appDel=[[UIApplication sharedApplication]delegate]; tabBarController.viewControllers=viewControllers; [appDel.window addSubview:tabBarController.view]; [viewControllers release]; </code></pre> <p>}</p> <p>Now as user goes to 4th tab to logout from app I have set a button to login again redirected to login view by adding code on button click as: </p> <pre><code>-(void)ClickOnLogin { LoginViewController *LoginViewOb=[[LoginViewController alloc]init]; LoginViewOb.hidesBottomBarWhenPushed = YES; [self.navigationController pushViewController:LoginViewOb animated:YES]; [LoginViewOb release]; } </code></pre> <p>but as login view is loaded the previous view is still at back of login view.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
