How To Make A Separate Login ViewController

i made login screen tab bar app, want make login screen appears when u first login , disappears after u log in, don't want in tab bar.

 

i've done similar in earlier version of applicationdidfinishlaunching: in app delegate. have not tried newer version of application:didfinishlaunchingwithoptions: expect work. when return login screen, return view controller have setup comment "the usual setup".

code:

  - (void)applicationdidfinishlaunching:(uiapplication *)application  {  	// usual setup.  	[self.window makekeyandvisible];    	[self login: self];  }    - (void) login: (id) sender  {     	loginvc * loginvc = [[loginvc alloc] initwithnibname:@"loginvc" bundle: nil];  	// setup of loginvc here.        	[self.navigationcontroller setnavigationbarhidden: yes animated: yes];  	[self.navigationcontroller pushviewcontroller: loginvc animated:yes];  	//[self presentmodalviewcontroller: loginvc animated: yes];    	[loginvc release];  }
