Iphone 如何从EKEvent存储中获取eventIdentifier？

现在我正在日历应用程序中处理EKEvent mange。我成功地将事件添加到eventStore。我需要从事件存储中获取事件标识符。 我使用以下代码访问eventIdentifier。但我在我的应用程序中总是为evetnIdentifier获取空值

EKEvent *event = [self eventAtIndexPath:indexPath];    
NSString *eventIdentifier]; = [[NSString alloc] initWithFormat:@"%@",event.eventIdentifier];

试试这个：

在你的

#import <EventKit/EventKit.h>

@property (nonatomic, retain) EKEventStore *eventStore;
@property (nonatomic, retain) EKCalendar *defaultCalendar;
@property (nonatomic, retain) NSMutableArray *eventsList;

---

希望对你有帮助。快乐编码。谢谢。

能否显示[self-EventIndexPath:indexPath]的代码@Yashesh，我得到event.title和event的其他属性。我无法仅获取eventIdentifier..检查此：-我已回答此问题，希望它有所帮助。

    NSArray *events_Array = [eventStore eventsMatchingPredicate: predicate];

    for (EKEvent *eventToCheck in events_Array)
    {
       [eventsList addObject:eventToCheck.calendarItemIdentifier ];
    }
