ios - BadgeValue not getting updated on UITabBarItem -

i use uitabbar , uitabbaritems it. can set badge value uitabbaritem before assigning tabbaritem tabbar. problem not able update badge value of tabbaritem.

here code able set badge value initially:

// array of tabbaritems nsmutablearray * tabs = [[nsmutablearray  alloc] init];  for(iterates few times) {     [tabs addobject:[[uitabbaritem alloc] initwithtitle:firstname image:nil tag:i]];     // set tabitem's property     [(uitabbaritem *)[tabs objectatindex:i] setfinishedselectedimage:[self convertimage:iconimage tosize:cgsizemake(iconwidth, tab_icon_height)] withfinishedunselectedimage:[self convertimage:iconimage tosize:cgsizemake(iconwidth, tab_icon_height)]];     [[tabs objectatindex:0] setbadgevalue:[nsstring stringwithformat:@"%d", 2]]; } // setting items of uitabbar [self.chattabbar setitems:tabs]; 

here, try update badge value. happens if nslog new badge value shows updated value see no change in ui.

[[self.chattabbar.items objectatindex:0] setbadgevalue:[nsstring stringwithformat:@"%d", 1]]; 

try it:

uiviewcontroller *carrinhovc = [self.tabbarcontroller.viewcontrollers objectatindex:0];              carrinhovc.tabbaritem.badgevalue = [nsstring stringwithformat:@"%d", 1]; 

carrinhovc uiviewcontroller want update badge value inside tabbar.
