   //在设置UITabBarCotroller字体颜色时，如果设置成高亮状态则会出现提醒：

  [self.tabBarItem setTitleTextAttributes:@{NSForegroundColorAttributeName:RGB_COLOR(255,40, 73)}forState:UIControlStateHighlighted];

   //提醒如下

button text attributes only respected for UIControlStateNormal, UIControlStateSelected, UIControlStateFocused, and UIControlStateDisabled. state = 1 is interpreted as UIControlStateSelected.

   //只需要将高亮状态改成选中状态即可去除打印出来的提醒

[self.tabBarItem setTitleTextAttributes:@{NSForegroundColorAttributeName:RGB_COLOR(255,40, 73)}forState:UIControlStateSelected];
