c++ - 我想在此代码中添加工作日

Question

好的，所以我有以下代码:

   if (!clock_is_24h_style()) {
   if (current_time->tm_hour <= 3)
  set_container_image(&time_format_image, RESOURCE_ID_NBC, GPoint(0, 0));

else if (current_time->tm_hour == 4 && current_time->tm_min <= 29)
  set_container_image(&time_format_image, RESOURCE_ID_ETODAY, GPoint(0, 0));

else if (current_time->tm_hour == 4 && current_time->tm_min >= 30)
  set_container_image(&time_format_image, RESOURCE_ID_9NEWSMORN, GPoint(0, 0));

else if (current_time->tm_hour == 5)
  set_container_image(&time_format_image, RESOURCE_ID_9NEWSMORN, GPoint(0, 0));

else if (current_time->tm_hour == 6)
  set_container_image(&time_format_image, RESOURCE_ID_9NEWSMORN, GPoint(0, 0));

else if (current_time->tm_hour == 12 && current_time->tm_min <= 29)
  set_container_image(&time_format_image, RESOURCE_ID_IMAGE_PM_MODE, GPoint(0, 0));

else if (current_time->tm_hour == 12 && current_time->tm_min >= 30)
  set_container_image(&time_format_image, RESOURCE_ID_NBC, GPoint(0, 0));

else if (current_time->tm_hour == 13 && current_time->tm_min <= 29)
  set_container_image(&time_format_image, RESOURCE_ID_WTC, GPoint(0, 0));

else if (current_time->tm_hour == 13 && current_time->tm_min >= 30)
  set_container_image(&time_format_image, RESOURCE_ID_BEARS, GPoint(0, 0));

else if (current_time->tm_hour == 14 && current_time->tm_min <= 29)
  set_container_image(&time_format_image, RESOURCE_ID_WTC, GPoint(0, 0));

else if (current_time->tm_hour == 14 && current_time->tm_min >= 30)
  set_container_image(&time_format_image, RESOURCE_ID_BEARS, GPoint(0, 0));

else if (current_time->tm_hour == 15)
  set_container_image(&time_format_image, RESOURCE_ID_NBC, GPoint(0, 0));

else if (current_time->tm_hour == 16)
  set_container_image(&time_format_image, RESOURCE_ID_9NEWS4, GPoint(0, 0));

else if (current_time->tm_hour == 17)
  set_container_image(&time_format_image, RESOURCE_ID_9NEWS5, GPoint(0, 0));

else if (current_time->tm_hour == 18 && current_time->tm_min <= 29)
  set_container_image(&time_format_image, RESOURCE_ID_9NEWS6, GPoint(0, 0));

else if (current_time->tm_hour == 18 && current_time->tm_min >= 30)
  set_container_image(&time_format_image, RESOURCE_ID_NN, GPoint(0, 0));

else if (current_time->tm_hour == 19)
  set_container_image(&time_format_image, RESOURCE_ID_NBC, GPoint(0, 0));

else if (current_time->tm_hour == 20)
  set_container_image(&time_format_image, RESOURCE_ID_WTC, GPoint(0, 0));

else if (current_time->tm_hour == 21)
  set_container_image(&time_format_image, RESOURCE_ID_BEARS, GPoint(0, 0));

else if (current_time->tm_hour == 22)
  set_container_image(&time_format_image, RESOURCE_ID_NBC, GPoint(0, 0));

else if (current_time->tm_hour == 23 && current_time->tm_min <= 34)
  set_container_image(&time_format_image, RESOURCE_ID_9NEWS10, GPoint(0, 0));

else if (current_time->tm_hour >= 23 && current_time->tm_min >= 35)
  set_container_image(&time_format_image, RESOURCE_ID_NBC, GPoint(0, 0));

else {
  layer_remove_from_parent(&time_format_image.layer.layer);
  bmp_deinit_container(&time_format_image);
}

它使 watch 上的图像在特定时间发生变化，这很棒，很棒。

然而，代码每天循环，并且每天都在做，而且它只在工作日(周一至周五)准确，并且想知道我如何才能做到这一点，以便代码仅适用于周一至周五，而单独的代码将适用于周六，另一个适用于周日。谢谢!

struct tm包含保存星期几的成员 tm_wday，其中 0 是星期日，6 是星期六。
