Question

My application is view based app. First view is login view. After login view i have MainMenuCcontroller which has a tabBarController:

 @interface RunnoMainMenuController : UIViewController {
IBOutlet UITabBarController *tabBarController;
 }

From login view controller, i am going to MainMenuController using this line of code:

 [self presentModalViewController:mainMenu animated:YES];

this controller has 4 tabs. Now i need to do some stuff in viewWillAppear of a tabBarItem. viewWillAppear is not called when i tap a tabBarItem. I have a button in one of those tabBarItem’s view which pops up a table view controller using presentModalViewController. This tableView uses dismissModalViewControllerAnimated:YES to disappear it. When i pop up this tableview and dismiss it then viewWillAppear of every tabBarItem works fine. If i will dismiss modalViewController in MainMenuController then it will again go back to login view. How can i dismiss modalViewController without leaving current view or any other solution? Thanks in advance.

You may need to consider how your views are presented. The tab bar controller should always be the window’s root view controller. From the Apple docs:

When deploying a tab bar interface, you must install this view as the
root of your window. Unlike other view controllers, a tab bar
interface should never be installed as a child of another view
controller.

Rather than present your login view as the root view and the tab bar as a modal view controller, try it the other way round. The tab bar controller as root, with the login view as presented as a modal view controller from the view controller of whichever tab is shown initially. Dismissing this will then reveal the tab bar controller.
