我生成这样的iCal文件:
BEGIN:VCALENDAR
VERSION:2.0
PRODID:-//Splash//EN
BEGIN:VEVENT
DTSTART;VALUE=DATE:20150912
DTEND;VALUE=DATE:20150912
SUMMARY:test
DESCRIPTION:xxx
BEGIN:VALARM
ACTION:DISPLAY
DESCRIPTION:test
TRIGGER:-P0DT16H0M0S
END:VALARM
BEGIN:VALARM
ACTION:DISPLAY
DESCRIPTION:test
TRIGGER:-P1DT16H0M0S
END:VALARM
BEGIN:VALARM
ACTION:DISPLAY
DESCRIPTION:test
TRIGGER:-P2DT16H0M0S
END:VALARM
END:VEVENT
END:VCALENDAR
当我使用谷歌日历导入此文件时,导入成功但我没有提醒,所以我对VALARM的错误以及如何解决这个问题?
