Question

我在我的应用程序中使用MBCalendarKit，我可以创建这样的事件：

CKCalendarEvent* aCKCalendarEvent = [[CKCalendarEvent alloc] init];
    [_infoDict setObject:@"Joint Meetings with KY State Horticulture Society, KY Vegetable Growers Association, KY Vineyard Society, and KY Farmer Market Association \nEmbassy Suites\nLexington, KY" forKey:@"Jan Joint"];
    aCKCalendarEvent.date = [dateformatter dateFromString: @"01/06/2014"];
    aCKCalendarEvent.title = @"Joint Meetings";
    aCKCalendarEvent.info = [_infoDict objectForKey:@"Jan Joint"];
    [eventsArray addObject: aCKCalendarEvent];
    [_eventsDict setObject: eventsArray forKey: [NSDate dateWithDay:06 month:01 year:2014]];

我可以在同一天创建另一个事件：

[_infoDict setObject:@"Washington, D.C." forKey:@"Congress Convenes"];
    aCKCalendarEvent = [[CKCalendarEvent alloc] init];
    aCKCalendarEvent.date = [dateformatter dateFromString: @"01/06/2014"];
    aCKCalendarEvent.title = @"113th Congress Convenes";
    [eventsArray addObject: aCKCalendarEvent];
    [_eventsDict setObject: eventsArray forKey: [NSDate dateWithDay:06 month:01 year:2014]];

然后我可以在不同的日子创建另一个事件，如下所示：

eventsArray = [[NSMutableArray alloc] init];
    [_infoDict setObject:@"Hilton Hotel \nMemphis, TN" forKey:@"Forage & Grassland"];
    aCKCalendarEvent = [[CKCalendarEvent alloc] init];
    aCKCalendarEvent.date = [dateformatter dateFromString: @"01/12/2014"];
    aCKCalendarEvent.title = @"American Forage & Grassland Council Annual Conference";
    [eventsArray addObject: aCKCalendarEvent];
    [_eventsDict setObject: eventsArray forKey: [NSDate dateWithDay:12 month:01 year:2014]];

我正在尝试遍历plist文件，该文件包含创建所有事件的所有事件。我可以这样做：

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"]];
        // NSDate *dateVariable = [dateformatter dateFromString:date];

        // Create events

        eventsArray = [[NSMutableArray alloc] init];
        aCKCalendarEvent = [[CKCalendarEvent alloc] init];
        aCKCalendarEvent.title = titleString;
        aCKCalendarEvent.date = [dateformatter dateFromString: date];
        [eventsArray addObject: aCKCalendarEvent];
        [_eventsDict setObject:eventsArray forKey:aCKCalendarEvent.date];
    }

问题是，如果我在同一天有多个事件，则只显示最新事件。我可以取出eventsArray = [[NSMutableArray alloc] init];行，但新事件不仅会出现在其他事件的正确日期，而且会出现在其他日子。所以我想我可以抛出这样的东西来检查我是否需要该行，然后将事件添加到eventsDict，但我在-[CKCalendarEvent isEqualToDate:]: unrecognized selector sent to instance 0xc6bb880上得到if ([[eventsArray objectAtIndex:i]isEqualToDate:aCKCalendarEvent.date])：

BOOL dateExists;

        for (int i = 0; i < [eventsArray count]; i++)
        {
            if ([[eventsArray objectAtIndex:i]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];
        }

所以基本上，我需要一种方法来遍历plist并确定程序是否需要在每个新事件上初始化eventsArray。

您正在将事件与日期进行比较。请参阅下面的比较事件日期的代码。

if ([[(CKCalendarEvent *)[eventsArray objectAtIndex:i] date]isEqualToDate:aCKCalendarEvent.date])
