使用EKEventStore从iPhone日历中删除事件 [英] Removing events from iPhone calendar with EKEventStore

问题描述

我试图删除我从iPhone日历创建的活动。

我试过这个，但总是返回NO：

  [eventStore removeEvent：event span：EKSpanThisEvent error：& err]; 
  

我创建的事件如下，它的工作原理：

  eventStore = [[EKEventStore alloc] init]; 
 
 event = [EKEvent eventWithEventStore：eventStore]; 
 
 event.title = @EVENT TITLE; 
 NSDateFormatter * dateFormatter = [[NSDateFormatter alloc] init]; 
 [dateFormatter setDateFormat：@yyyy-MM-dd：HH：mm]; 
 
 
 NSDate * date = [[NSDate alloc] init]; 
 date = [dateFormatter dateFromString：@2010-8-15：12：30]; 
 [date retain]; 
 
 event.startDate = date; 
 event.endDate = [[NSDate alloc] initWithTimeInterval：600 sinceDate：event.startDate]; 
 
 [event setCalendar：[eventStore defaultCalendarForNewEvents]]; 
 NSError * err; 
 [eventStore saveEvent：event span：EKSpanThisEvent error：& err]; 
  

有办法删除此活动吗？

感谢，

$ b $创建事件后，我将eventIdentifier保存在数组中：

 <$> c $ c> [eventStore saveEvent：event span：EKSpanThisEvent error：& err]; 
 NSString * str = [[NSString alloc] initWithFormat：@％@，event.eventIdentifier]; 
 [arrayofCalIDs addObject：str]; 
  

要删除事件：

  EKEventStore * store = [[[EKEventStore alloc] init] autorelease]; 
 EKEvent * event2 = [store eventWithIdentifier：[arrayofCalIDs objectAtIndex：i]]; 
 if（event2！= nil）{
 NSError * error = nil; 
 [store removeEvent：event2 span：EKSpanThisEvent error：& error]; 
} 
 [myPath release]; 
  

I'm trying to remove events that i have created from the iPhone calendar.

I tried this, but it always returns NO:

  [eventStore removeEvent:event span:EKSpanThisEvent error:&err];

I created the event as follows and it works:

eventStore = [[EKEventStore alloc] init];

event = [EKEvent eventWithEventStore:eventStore];

event.title = @"EVENT TITLE";
NSDateFormatter *   dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"yyyy-MM-dd:HH:mm"];


NSDate * date = [[NSDate alloc] init];
date = [dateFormatter dateFromString:@"2010-8-15:12:30"];
[date retain];

event.startDate = date;
event.endDate = [[NSDate alloc] initWithTimeInterval:600 sinceDate:event.startDate];

[event setCalendar:[eventStore defaultCalendarForNewEvents]];
NSError *err;
[eventStore saveEvent:event span:EKSpanThisEvent error:&err]; 

Is there a way to remove this event? Or it would be be better that if I try to write this event again it only modifies it instead of creating a new one.

Thanks,

解决方案

After creating the event I save the eventIdentifier in an array:

[eventStore saveEvent:event span:EKSpanThisEvent error:&err]; 
   NSString* str = [[NSString alloc] initWithFormat:@"%@", event.eventIdentifier];
[arrayofCalIDs addObject:str];

To delete the events:

EKEventStore* store = [[[EKEventStore alloc] init] autorelease];
   EKEvent* event2 = [store eventWithIdentifier:[arrayofCalIDs objectAtIndex:i]];
if (event2 != nil) {  
  NSError* error = nil;
  [store removeEvent:event2 span:EKSpanThisEvent error:&error];
} 
[myPath release];
