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];
