Objective c segue和EKEventViewController刷新

我有一个

UITableViewController

，它在使用以下代码选择行时推送一个

EKEventViewController

：

-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{
     if([segue.identifier isEqualToString:@"eventHandler"]){
         if (_currentPanel.event_identifier != nil) {
             self.event = [[[CalendarHelper sharedInstance] store] eventWithIdentifier:_currentPanel.event_identifier];
    } else {
        EKEventStore *store = [[CalendarHelper sharedInstance] store];
        self.event = [EKEvent eventWithEventStore:store];
        _event.startDate = self.qualifyDate;
        _event.endDate = self.qualifyDate;

        _event.title = @"test identifier" ;
        _event.calendar = [[CalendarHelper sharedInstance] calendar];
    }
    self.eventDatailController =  (EKEventViewController *)[segue destinationViewController];

    self.eventDatailController.event = self.event;
    self.eventDatailController.allowsEditing = YES;
    self.eventDatailController.allowsCalendarPreview = YES;
    self.eventDatailController.delegate = self;
}
}

事件显示良好，但通过编辑按钮在

EKEventViewController

中编辑事件并完成点击完成按钮后，

EKEventViewController

中的事件不会相应刷新

SimpleEKDemo

工作正常，但不使用

prepareForSegue:sender: 

但是

我做错了什么？

您始终可以通过执行以下操作从didSelectRowAtIndexPath调用PrepareForsgue方法：

[self prepareForSegue:@"EKEventViewController" sender:self];

[self prepareForSegue:@"EKEventViewController" sender:self];
