从iPhone的日历中删除活动 [英] Deleting an event from iPhone's calendar

问题描述

我想根据使用者要求从日历中删除活动。这是我想出来的：

  //删除事件
 EKEventStore * eventStore = [[EKEventStore alloc ] 在里面]; 
 EKEvent * event = [EKEvent eventWithEventStore：eventStore]; 
 event.title = appDelegate.title1; 
 event.startDate = appDelegate.recAddDate; 
 event.endDate = appDelegate.currentDateName; 
 [event setCalendar：[eventStore defaultCalendarForNewEvents]]; 
 NSError * err; 
 [eventStore removeEvent：event span：EKSpanThisEvent error：& err]; 
  

下面是我调用的函数，从事件数组中删除事件。 Items数组用于从iPhone日历获取事件

   - （BOOL）removeEvent：（EKEvent *）event span：（EKSpan）跨越错误：（NSError **）错误{
 VoiceRecorderAppDelegate * appDelegate =（VoiceRecorderAppDelegate *）[[UIApplication sharedApplication] delegate]; 
 [items removeObjectAtIndex：appDelegate.objectindexpath]; 
} 
  

解决方案

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

，然后标识要删除的活动，然后删除该活动。

  EKEventStore * store = [[EKEventStore alloc] init]; 
 EKEvent * eventToRemove = [store eventWithIdentifier：[arrayofEventId objectAtIndex：i]]; 
 if（eventToRemove！= nil）{
 NSError * error = nil; 
 [store removeEvent：eventToRemove span：EKSpanThisEvent error：& error]; 
} 
  

同样不要忘记从arrayofEventId中删除该事件。 p>

I am trying to delete an event from the Calendar on user request. This is what I've come up with:

// Deleting Event
    EKEventStore *eventStore = [[EKEventStore alloc] init];
EKEvent *event  = [EKEvent eventWithEventStore:eventStore];
event.title     = appDelegate.title1;
event.startDate = appDelegate.recAddDate;
event.endDate   = appDelegate.currentDateName;
[event setCalendar:[eventStore defaultCalendarForNewEvents]];
NSError *err;
[eventStore removeEvent:event span:EKSpanThisEvent error:&err];

Below is the function I'm calling to remove the event from the event array. Items array is used to fetch events from iPhone calendar

- (BOOL)removeEvent:(EKEvent *)event span:(EKSpan)span error:(NSError **)error{
    VoiceRecorderAppDelegate *appDelegate = (VoiceRecorderAppDelegate *)[[UIApplication sharedApplication] delegate];
    [items removeObjectAtIndex:appDelegate.objectindexpath];
}

解决方案

Firstly, save the eventId for the event while adding/saving events to the calendar.

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

and then identify the event you want to remove ande then remove that event.

EKEventStore* store = [[EKEventStore alloc] init];
EKEvent* eventToRemove = [store eventWithIdentifier:[arrayofEventId objectAtIndex:i]];
 if (eventToRemove != nil) {  
   NSError* error = nil;
  [store removeEvent:eventToRemove span:EKSpanThisEvent error:&error];
 } 

Also don't forget to remove that event from arrayofEventId as well.
