我正在尝试使用以下代码在日历中添加会议详细信息。但它不起作用。我总是得到错误代码（其他部分正在执行）。
EKEventStore *eventSotre = [[EKEventStore alloc] init];
EKEvent *event = [EKEvent eventWithEventStore:eventSotre];
event.title= @"Event Title";
NSDate *duedate = [[NSDate alloc] init];
event.startDate = duedate;
// also tried with below
// event.startDate = [[NSDate alloc] initWithTimeInterval:200 sinceDate:duedate];
event.endDate= [[NSDate alloc] initWithTimeInterval:600 sinceDate:duedate];
NSArray *arrAlarm = [NSArray arrayWithObject:[EKAlarm alarmWithAbsoluteDate:duedate]];
event.alarms= arrAlarm;
[event setCalendar:[eventSotre defaultCalendarForNewEvents]];
NSError *err;
BOOL isSuceess=[eventSotre saveEvent:event span:EKSpanThisEvent error:&err];
if(isSuceess){
UIAlertView *alertview = [[UIAlertView alloc] initWithTitle:@"Event" message:@"Event added in calendar" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
[alertview show];
[alertview release];
}
else{
UIAlertView *alertview = [[UIAlertView alloc] initWithTitle:@"Error" message:[err description] delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
[alertview show];
[alertview release];
}
[eventSotre release];
知道为什么我要面对这个吗？我的代码中也有#import <EventKit/EventKit.h>，我也添加了相同的框架。
