// Check if the Power On Reset flag is set
RCC_APB1PeriphClockCmd(RCC_APB1Periph_PWR, ENABLE);
/* Allow access to BKP Domain */
PWR_BackupAccessCmd(ENABLE);
/* Wait until last write operation on RTC registers has finished */
RTC_WaitForLastTask();
这样就可以了~！

后面加上：
// Check if the Power On Reset flag is set
RCC_APB1PeriphClockCmd(RCC_APB1Periph_PWR, ENABLE);
/* Allow access to BKP Domain */
PWR_BackupAccessCmd(ENABLE);
/* Wait until last write operation on RTC registers has finished */
RTC_WaitForLastTask();
