NSMutableDictionary *dictAttr = [NSMutableDictionary dictionary];

//dictAttr[NSForegroundColorAttributeName] = [UIColor orangeColor];

//dictAttr[NSFontAttributeName]=[UIFont systemFontOfSize:13];

  [dictAttr setObject:[UIColor orangeColor] forKey:NSForegroundColorAttributeName];

[newNavVc.navigationBar setTitleTextAttributes:dictAttr];

newVc.tabBarItem.title = title;

newVc.tabBarItem.image = image;

newVc.tabBarItem.selectedImage = selectImg;

[newNavVc addChildViewController:newVc];
