少叙述，多代码，简单粗暴最高效。

tabBarItem的tiltle属性设置

NSMutableDictionary *selectedAttrs = [NSMutableDictionary dictionary];    selectedAttrs[NSFontAttributeName] = [UIFont systemFontOfSize:12];    selectedAttrs[NSForegroundColorAttributeName] = [UIColor darkGrayColor];    [vc01.tabBarItem setTitleTextAttributes:selectedAttrs forState:UIControlStateSelected];

[UINavigationBar appearance];    // 通过appearance统一设置所有UITabBarItem的文字属性    // 后面带有UI_APPEARANCE_SELECTOR的方法, 都可以通过appearance对象来统一设置    NSMutableDictionary *attrs = [NSMutableDictionary dictionary];    attrs[NSFontAttributeName] = [UIFont systemFontOfSize:12];    attrs[NSForegroundColorAttributeName] = [UIColor grayColor];    NSMutableDictionary *selectedAttrs = [NSMutableDictionary dictionary];    selectedAttrs[NSFontAttributeName] = attrs[NSFontAttributeName];    selectedAttrs[NSForegroundColorAttributeName] = [UIColor darkGrayColor];    UITabBarItem *item = [UITabBarItem appearance];    [item setTitleTextAttributes:attrs forState:UIControlStateNormal];    [item setTitleTextAttributes:selectedAttrs forState:UIControlStateSelected];
