iphone google reminder problem

I am integerating iphone app with google calendar using gdata api's. Done with event add, delete, fetch, update

but the reminder is not adding in calenda开发者_运维百科r event

My code is :

NSDate *anHourFromNow = [NSDate dateWithTimeIntervalSinceNow:60*60];

GDataDateTime *startDateTime = [GDataDateTime dateTimeWithDate:[NSDate date] timeZone:[NSTimeZone systemTimeZone]];

GDataDateTime *endDateTime = [GDataDateTime dateTimeWithDate:anHourFromNow timeZone:[NSTimeZone systemTimeZone]];

GDataReminder *reminder = [GDataReminder reminder];

[reminder setMinutes:@"10"];

GDataWhen *when = [GDataWhen whenWithStartTime:startDateTime endTime:endDateTime];

[when addReminder:reminder];

[event addTime:when];

if (event)

{ // Post the event.

NSURL *altLinkURL = [[calendar alternateLink] URL];

[service fetchEntryByInsertingEntry:event forFeedURL:altLinkURL delegate:nil didFinishSelector:nil]; }

Using this code event is added in calendar but reminder is not appearing when I manually see in this event in google calendar

Reminder should have an explicit setMethod: call; discussion is here.
