ios7 - iOS 7 Tab bar icons temporarily disappear when on More tab -

when add view controller embedded navigation controller, tab bar, icon + title disappear briefly when coming more tab.

however when view controller added such, icon+image okay , don't disappear.

i've tried many things already, , out of options. ideas?

here's appdelegate code:

- (bool)application:(uiapplication *)application didfinishlaunchingwithoptions:(nsdictionary *)launchoptions {     self.window = [[uiwindow alloc] initwithframe:[[uiscreen mainscreen] bounds]];     self.tabbarcontroller = [[uitabbarcontroller alloc] init];      // must placed here, before tabs added.  otherwise navigation bar     // overlap status bar.     [[uiapplication sharedapplication] setstatusbarhidden:no withanimation:uistatusbaranimationslide];      [self addviewcontrollerstotabbar];     self.window.rootviewcontroller = self.tabbarcontroller;     self.window.backgroundcolor    = [uicolor whitecolor];     [self.window makekeyandvisible];      return yes; }  - (void)addviewcontrollerstotabbar {     nsarray* tabbarclassnames =     @[       nsstringfromclass([firstviewcontroller  class]),       nsstringfromclass([secondviewcontroller class]),       nsstringfromclass([firstviewcontroller  class]),       nsstringfromclass([firstviewcontroller  class]),       nsstringfromclass([firstviewcontroller  class]),       nsstringfromclass([secondviewcontroller class]),       nsstringfromclass([firstviewcontroller  class]),       ];      nsmutablearray* viewcontrollers = [nsmutablearray array];     (nsstring* classname in tabbarclassnames)     {         uiviewcontroller*       viewcontroller = [[nsclassfromstring(classname) alloc] init];         uinavigationcontroller* navigationcontroller;          navigationcontroller = [[uinavigationcontroller alloc] initwithrootviewcontroller:viewcontroller];          [viewcontrollers addobject:navigationcontroller];     }      [viewcontrollers addobject:[[firstviewcontroller alloc] init]]; // 1 fine.      self.tabbarcontroller.viewcontrollers        = viewcontrollers;     self.tabbarcontroller.selectedviewcontroller = viewcontrollers[2]; } 

and view controllers literally nothing more than:

@implementation secondviewcontroller  - (instancetype)init {     if (self = [super init])     {         self.title            = @"second";         self.tabbaritem.image = [uiimage imagenamed:@"second.png"];     }      return self; }  @end 

holy shit, spent time on bug, here's workaround. instead of:

navigationcontroller = [[uinavigationcontroller alloc] initwithrootviewcontroller:viewcontroller]; 

i created own navigationcontroller subclass of uinavigationcontroller:

@implementation navigationcontroller  - (instancetype)initwithrootviewcontroller:(uiviewcontroller*)rootviewcontroller {     if (self = [super initwithrootviewcontroller:rootviewcontroller])     {         nsstring* classname = nsstringfromclass([rootviewcontroller class]);         nsstring* name      = [classname stringbyreplacingoccurrencesofstring:@"viewcontroller" withstring:@""];          self.tabbaritem.image = [uiimage imagenamed:[nsstring stringwithformat:@"%@tab.png", name]];     }      return self; }  @end 

and do:

navigationcontroller = [[navigationcontroller alloc] initwithrootviewcontroller:viewcontroller]; 

prerequisite tab images have same base name view controller class name, case in app.

i setting self.tabbaritem.image inside view controllers' init method, , seems cause effect seeing. in addition using own navigation controller, deleted setting tabbaritem in each individual view controller.
