2.設置選中狀態字體顏色

[tabBarItem setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:

[UIFont fontWithName:@"Helvetica-Bold" size:10],

NSFontAttributeName,[UIColor colorWithRed:153/255.0 green:153/255.0 blue:153/255.0 alpha

nil] forState:UIControlStateNormal];

UITabBarController *tabBar=[[UITabBarController alloc]init];

tabBar.viewControllers=@[_homeNav,_erShouNav,_orderNav,_tuiJianNav];

tabBar.view.backgroundColor = [UIColor whiteColor];

tabBar.selectedIndex = 0;//默認展示頁

tabBar.delegate=self;
