回答1:

In appDelegate place your tabBar and in side loginView ,add this tabBar

TUTAppDelegate *appdelegte =(TUTAppDelegate*)[[UIApplication sharedApplication]delegate];

[[appdelegte window]addSubview:[[appdelegte motivationalTabBar]view]];

On button press remove TabBar

TUTAppDelegate *appDelegate = (TUTAppDelegate *)[[UIApplication sharedApplication] delegate];
[[[appDelegate motivationalTabBar] view]removeFromSuperview]

回答2:

Add your tabBar controller to [appdelegte window] first and then present Login View Controller on it. When user log-ins successfully, dismiss Login View Controller. Again when you click on barbutton to come to that loginViewController , present Login View Controller on tabBar controller. In this case there is no need to add and remove tabBar again and again.

回答3:

 AppDelegate *delegate = (AppDelegate *) [[UIApplication sharedApplication] delegate];
[delegate.tabBarController.view removeFromSuperview];
[delegate.window addSubview:delegate.loginViewController.view];

i got solution for my problem with this code. hope this will help for someone.

thanks for all answers.
