ios - 没有从字典中得到正确的信息

Question

我正在使用 MBCalendarKit 并使其正常工作，但我正在尝试为我创建的每个事件使用信息字典，以便在日历视图中选择事件后在详细信息页面上显示详细信息。我的事件都是从 plist 文件创建的：

这是我创建事件的地方：

// Read Events.plist

    NSString *path = [[NSBundle mainBundle] pathForResource:@"Events" ofType:@"plist"];
    NSDictionary *dictPri = [[NSMutableDictionary alloc]initWithContentsOfFile:path];
    NSMutableArray *arrEvents = [[NSMutableArray alloc] initWithArray:[dictPri objectForKey:@"List"]];

    // Loop through each item in List array of Events.plist

    for (NSDictionary *dict in arrEvents)
    {
        NSString *titleString = nil;
        NSString *date = nil;

        titleString = [NSString stringWithFormat:@"%@",[dict objectForKey:@"Title"]];
        date = [NSString stringWithFormat:@"%@",[dict objectForKey:@"Date"]];

        // Create events

        aCKCalendarEvent = [[CKCalendarEvent alloc] init];
        aCKCalendarEvent.title = titleString;
        aCKCalendarEvent.date = [dateformatter dateFromString: date];
        aCKCalendarEvent.info = [dict objectForKey:@"Info"];

        _information = [NSString stringWithFormat:@"%@", aCKCalendarEvent.info];

        BOOL dateExists;

        for (int i = 0; i < [eventsArray count]; i++)
        {
            if ([[(CKCalendarEvent *)[eventsArray objectAtIndex:i]date]isEqualToDate:aCKCalendarEvent.date])
            {
                // Array already contains object with this date

                dateExists = YES;
            }
            else
            {
                dateExists = NO;
            }

            NSLog(@"%c", dateExists);
        }

        if (dateExists == YES)
        {
            [eventsArray addObject:aCKCalendarEvent];
            [_eventsDict setObject:eventsArray forKey:aCKCalendarEvent.date];
        }
        else
        {
            eventsArray = [[NSMutableArray alloc]init];
            [eventsArray addObject:aCKCalendarEvent];
            [_eventsDict setObject:eventsArray forKey:aCKCalendarEvent.date];
        }
    }

这是选择事件时发生的代码：

- (void)calendarView:(CKCalendarView *)CalendarView didSelectEvent:(CKCalendarEvent *)event;
{
    NSDateFormatter *dateformatter = [[NSDateFormatter alloc] init];
    [dateformatter setDateFormat:@"MM/dd/yyyy"];

    EventDetail *detail = [[EventDetail alloc] initWithNibName:nil bundle:nil];

    detail.details = _information;
    detail.eventTitle = event.title;
    detail.eventDate = [dateformatter stringFromDate:event.date];

    [self.navigationController pushViewController:detail animated:YES];

我的问题是详细视图上显示的详细信息始终是 plist 文件中最后一个事件的详细信息，因此无论选择哪个事件，详细信息总是说 San Antonio, TX。

我已经变成detail.details = _information;了detail.details = [event.info objectForKey:@"Info"]; 但是，这导致-[__NSCFString objectForKey:]: unrecognized selector sent to instance 0xbcc2000

我通过改变一些- (void)calendarView:(CKCalendarView *)CalendarView didSelectEvent:(CKCalendarEvent *)event;方法让它工作了。

这是选择事件的工作代码：

NSDateFormatter *dateformatter = [[NSDateFormatter alloc] init];
    [dateformatter setDateFormat:@"MM/dd/yyyy"];

    EventDetail *detail = [[EventDetail alloc] initWithNibName:nil bundle:nil];

    _information = [NSString stringWithFormat:@"%@", event.info];

    detail.details = _information;
    detail.eventTitle = event.title;
    detail.eventDate = [dateformatter stringFromDate:event.date];

    [self.navigationController pushViewController:detail animated:YES];
