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.

enter image description here

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:

enter image description here

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.

-
i'm trying subclass qstyleditemdelegate remove focus rectangle in qcombobox . even though i'm calling base implementation of paint function , nothing else, result different. looks if parts of style-sheet influence bounding box of item taken consideration. class pstyleditemdelegate(qstyleditemdelegate): def __init__(self, *args, **kwds): super(pstyleditemdelegate, self).__init__(*args, **kwds) def paint(self, *args, **kwargs): qstyleditemdelegate.paint(*args, **kwargs) what have paint unmodified qstyleditemdelegate ? as suggested tried replacing pyside pyqt4 , works, appears bug. update pyside 1.1.2 1.2.1 result same. unfortunately switch breaks other parts of code, if there no other suggestions i'm going accept answer. edit bug tracked here
