使用其标识符从设备的日历中删除EKEvent [英] Deleting an EKEvent from device's calendar using its identifier

问题描述

我正在创建EKEvent，保存它并保存其标识符。我想访问此标识符并删除特定事件。我能够从数据库中检索正确的标识符。但是，事件不会从我的设备日历中删除。
删除事件的代码：
`NSError * err;

I am creating EKEvent, saving it and saving its identifier as well. I wanna access this identifier and delete the specific Event. I am able to retrieve the proper Identifier from database. However, the Event isn't getting deleted from my Device's calendar. My code to delete the event : `NSError* err;

    EKEvent *myEvent = [EKEvent eventWithEventStore:homeobj.eventDB];

    myEvent = [homeobj.eventDB eventWithIdentifier:[dbObj selectEventIdentifier:mypass]];

    [homeobj.eventDB removeEvent:myEvent span:EKSpanThisEvent commit:YES error:&err];

`

推荐答案

删除使用此代码

-(void)removeMeWithIndex:(int)index
{
    EKEvent* eventToRemove = [eventStore eventWithIdentifier:[arrayofEventId objectAtIndex:index]];

    if (eventToRemove != nil) {
        NSError* error = nil;
        [eventStore removeEvent:eventToRemove span:EKSpanThisEvent error:&error];
    }
}

-(IBAction)remove
{
  [self removeMeWithIndex:0];
}

我已更新我的代码以检查id是否存在

I have updated my code to check if id exists or not as

-(void)removeMeWithIndex:(int)index
{
    NSLog(@"id is %@",[[NSUserDefaults standardUserDefaults] valueForKey:@"id"]);
    EKEvent* eventToRemove = [eventStore eventWithIdentifier:[[NSUserDefaults standardUserDefaults] valueForKey:@"id"]];

    if (eventToRemove != nil) {
        NSError* error = nil;
        [eventStore removeEvent:eventToRemove span:EKSpanThisEvent error:&error];
    }
}

删除后的输出是......

您的ID是这样的吗？

在设备的日历应用中创建事件检查后。
