我的iPhone上有一种奇怪的行为。我正在创建一个使用日历事件（EventKit）的应用程序。使用的类如下：
.h one
#import "GenericManager.h"
#import <EventKit/EventKit.h>
#define oneDay 60*60*24
#define oneHour 60*60
@protocol CalendarManagerDelegate;
@interface CalendarManager : GenericManager
/*
* metodo che aggiunge un evento ad un calendario di nome Name nel giorno onDate.
* L'evento da aggiungere viene recuperato tramite il dataSource che è quindi
* OBBLIGATORIO (!= nil).
*
* Restituisce YES solo se il delegate è conforme al protocollo CalendarManagerDataSource.
* NO altrimenti
*/
+ (BOOL) addEventForCalendarWithName:(NSString *) name fromDate:(NSDate *)fromDate toDate: (NSDate *) toDate withDelegate:(id<CalendarManagerDelegate>) delegate;
/*
* metodo che aggiunge un evento per giorno compreso tra fromDate e toDate ad un
* calendario di nome Name. L'evento da aggiungere viene recuperato tramite il dataSource
* che è quindi OBBLIGATORIO (!= nil).
*
* Restituisce YES solo se il delegate è conforme al protocollo CalendarManagerDataSource.
* NO altrimenti
*/
+ (BOOL) addEventsForCalendarWithName:(NSString *) name fromDate:(NSDate *)fromDate toDate: (NSDate *) toDate withDelegate:(id<CalendarManagerDelegate>) delegate;
@end
@protocol CalendarManagerDelegate <NSObject>
// viene inviato quando il calendario necessita informazioni sull' evento da aggiungere
- (void) calendarManagerDidCreateEvent:(EKEvent *) event;
@end

实际上，在我的iphone上我得到了日志：
获取旧的= =（null） 19/12/2012 11：33：09.520 AppCampeggioSingolo [730：8 b1b]创建新日历 19/12/2012 11：33：09.558 AppCampeggioSingolo [730：8 b1b]已保存的日历EKCalendar
每次我添加一个活动，然后我看，我在他添加的iCal日历活动中找不到它。然而，在我的一个朋友的iPhone上，一切正常。我怀疑问题源于代码，但只是不明白它可能是什么。
我昨天整天都在搜索，今天部分时间在Google搜索，但还没有找到任何内容。
非常感谢任何帮助
编辑：我忘记了这个电话[CalendarManager addEventForCalendarWithName: @"myCalendar" fromDate:fromDate toDate: toDate withDelegate:self];
只需设置事件的标题和注释，如下
- (void) calendarManagerDidCreateEvent:(EKEvent *) event
{
event.title = @"the title";
event.notes = @"some notes";
}
答案 0 :(得分：0)
解决了!!!今天iPhone被卡在黑屏上，无法关闭它。所以'我决定恢复它......魔术！日历现在正常工作......：）
奇怪的信息方式：p
