我在 IOS 7 中的日期格式有问题我编写了以下代码：

// eventstart = "12.NOV.2013 13:45" is a NSString
// eventend = "13.NOV.2013 14:12" is a NSString

NSTimeZone *gmt = [NSTimeZone timeZoneWithAbbreviation:@"GMT"];
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:@"dd.MMM.yyyy HH:mm:ss"];
NSDateFormatter *dateFormat2 = [[NSDateFormatter alloc] init];
[dateFormat2 setDateFormat:@"dd.MMM.yyyy HH:mm:ss"];
[dateFormat setTimeZone:gmt];
[dateFormat2 setTimeZone:gmt];
NSDate *date = [dateFormat2 dateFromString:eventstart];
NSDate *date2 = [dateFormat dateFromString:eventend];

现在我将事件设置为：

    if ([eventStore respondsToSelector:@selector(requestAccessToEntityType:completion:)])

{[eventStore requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted, NSError *error) {dispatch_async(dispatch_get_main_queue(), ^{

            if (error)

            { }

            else if (!granted)

            { }

            else

            {           
               event.startDate = date;
               event.endDate   = date2;
               event.calendar  = [eventStore defaultCalendarForNewEvents];
               NSString *title = [NSString stringWithFormat:@"%@",_type_s];
               event.title     = title;
               NSString *location = [NSString stringWithFormat:@"%@-%@",_from_s,_to_s];
               event.location  = location;
               NSString *notes = [NSString stringWithFormat:@"in GMT: \n %@ \n to \n             %@",_starttime_s,_endtime_s];
               event.notes     = notes;
              [event setCalendar:[eventStore defaultCalendarForNewEvents]];
              NSError *err;
              [eventStore saveEvent:event span:EKSpanThisEvent error:&err];
 }
});
}];

问题是它适用于模拟器，但不适用于 Iphone 本身！我想我的日期格式有问题，因为调试器中的 date or date2 总是 nill .....

有人可以帮我解决这个问题或给我解决问题的提示吗！

您应该将其用作日期格式：

[dateFormat2 setDateFormat:@"dd.LLL.yyyy HH:mm:ss"];

那应该可以解决问题。
