ios - UIBarButton Title Only Shows Periodically -

i'm adding uitoolbar uiviewcontroller programmatically.

the problem have when view created buttons in toolbar "do" show not show title text.

if wait 10 - 20 seconds or longer titles show.

i tried calling setneedsdisplay , setneedslayout force ui yo update straight doesnt work.

am doing ridiculous? can't life of me figure out why title don't show immediately.

-(id)initwithframe:(cgrect)frame {     self= [super init];      if (self) {         uiview  *view=[[uiview alloc]initwithframe:frame];         self.view=view;         cellloader = [uinib nibwithnibname:cellclassname bundle:[nsbundle mainbundle]] ;          self.tableview=[[uitableview alloc]initwithframe:cgrectmake(self.view.frame.origin.x,                                                                     self.view.frame.origin.y+44,                                                                     self.view.frame.size.width,                                                                     self.view.frame.size.height-44)                                                    style:uitableviewstyleplain];          [self.tableview registerclass:[mycell class] forcellreuseidentifier:@"mycell"];         [self.view addsubview:self.tableview];           self.tableview.datasource=self;         self.tableview.delegate=self;         //[self.tableview setcontentinset:uiedgeinsetsmake(44, 0, 0, 0)];          navitem = [[uinavigationitem alloc] init];          uilabel* lbnavtitle = [[uilabel alloc] initwithframe:cgrectmake(-200,50,100,40)];         [lbnavtitle setbackgroundcolor:[uicolor clearcolor]];         lbnavtitle.textalignment = nstextalignmentleft;         [lbnavtitle settextcolor:[uicolor whitecolor]];         lbnavtitle.text = nslocalizedstring(@"",@"");         navitem.titleview = lbnavtitle;          navibar = [[uinavigationbar alloc] init];         navibar.barstyle=uibarstyleblack;         navibar.items = [nsarray arraywithobject:navitem];         navibar.frame = cgrectmake(0.0, 0, self.view.frame.size.width, 44.0);           toolbar = [[uitoolbar alloc] initwithframe:cgrectmake(0, 0, 350, 44)];          toolbar.barstyle=uibarstyleblack;         nsmutablearray *buttons = [[nsmutablearray alloc] initwithcapacity:7];               button1=[[uibarbuttonitem alloc]                                                initwithtitle:@"button 1 text"                                                style:uibarbuttonitemstylebordered target:self                                                action:@selector(buttononepressed:)];         [buttons addobject: button1];          uibarbuttonitem *spacer1 = [[uibarbuttonitem alloc]                                     initwithbarbuttonsystemitem:uibarbuttonsystemitemfixedspace                                     target:nil                                     action:nil];          [buttons addobject:spacer1];          button2=[[uibarbuttonitem alloc]                                             initwithtitle:@"button 2 text"                                             style:uibarbuttonitemstylebordered target:self                                             action:@selector(button2pressed:)];         [buttons addobject:button2];             [toolbar setitems:buttons animated:no];                [self.view addsubview:toolbar];               [navibar setneedsdisplay];             [toolbar setneedsdisplay];             [self.view setneedsdisplay];            }      return self;  } 

ok, if viewcontroller, don't want create view hierarchy in init method, instead, use viewdidload method. (and don't have set self.view yourself, default implementation in uiviewcontroller you)

also, you're creating uinavigationbar , uitoolbar, setting same frames both when add toolbar subview... (i'll consider uinavigationbar junk code too)

- (void)viewdidload {      cellloader = [uinib nibwithnibname:cellclassname bundle:[nsbundle mainbundle]] ;      self.tableview=[[uitableview alloc]initwithframe:cgrectmake(self.view.frame.origin.x,                                                                       self.view.frame.origin.y+44,                                                                     self.view.frame.size.width,                                                                     self.view.frame.size.height-44)                                                    style:uitableviewstyleplain];      [self.tableview registerclass:[mycell class] forcellreuseidentifier:@"mycell"];     [self.view addsubview:self.tableview];      self.tableview.datasource=self;     self.tableview.delegate=self;      toolbar = [[uitoolbar alloc] initwithframe:cgrectmake(0, 0, 350, 44)];     toolbar.barstyle=uibarstyleblack;        uibarbuttonitem *button1 = [[uibarbuttonitem alloc] initwithtitle:@"button 1 text"                                                   style:uibarbuttonitemstylebordered target:self                                                  action:@selector(buttononepressed:)];         uibarbuttonitem *spacer1 = [[uibarbuttonitem alloc] initwithbarbuttonsystemitem:uibarbuttonsystemitemfixedspace                                     target:nil                                     action:nil];      uibarbuttonitem *button2 = [[uibarbuttonitem alloc] initwithtitle:@"button 2 text"                                                  style:uibarbuttonitemstylebordered target:self                                                 action:@selector(button2pressed:)];        // using objective-c litterals shorter code using nsmutablearray !     [toolbar setitems:@[button1, spacer1, button2] animated:no];        [self.view addsubview:toolbar];     }  } 

normally, that's need (no call setneedsdisplay, these done automatically when adding subviews)
