objective c - UINavigationController flow for login ios -

solved:

once user has logged in / signed up, use following code transition main storyboard...

 uiwindow* window = [[uiapplication sharedapplication] keywindow];   window.rootviewcontroller = [[uistoryboard storyboardwithname:@"main" bundle:[nsbundle mainbundle]] instantiateinitialviewcontroller]; 

i have following uinavigationcontroller flow handle logging in...the top segue after tabbarcontroller goes uinavigationcontroller root viewcontroller.

when user logged in "this segue works" executed user doesn't have log in @ login screen. works perfectly. issue run when user has login...the segue login/signup screen login screen works perfectly, when go login screen tabbar following happens:

this shouldn't happen because have following code in viewcontroller.m (gotten here called)

- (void)viewdidload {     ...     self.navigationitem.title = @"messages";     self.navigationitem.hidesbackbutton = yes;      nslog(@"gotten here");     ... } 

does know why happening?

i keep login flow separate normal app flow. means don't link segue login screen app, handle in appdelegate:

if ([myuserhandler sharedhelper].isauthenticated) {     [self presentmaininterface]; } else {     [self presentwelcomeinterface]; } 

where first method this:

- (void)presentmaininterface {     self.window.rootviewcontroller = [[uistoryboard storyboardwithname:@"main" bundle:[nsbundle mainbundle]] instantiateinitialviewcontroller]; } 

and other presents login screen:

- (void)presentwelcomeinterface {        uiviewcontroller* rootcontroller = [[uistoryboard storyboardwithname:@"main" bundle:[nsbundle mainbundle]] instantiateviewcontrollerwithidentifier:@"loginscreen"];      uinavigationcontroller* navigation = [[uinavigationcontroller alloc] initwithrootviewcontroller:rootcontroller];     self.window.rootviewcontroller = navigation; } 

this way login screen loaded when user not authenticated.
