问题创建活动使用MBCalendarKit

Question

我使用MBCalendarKit在我的应用程序，我能创造这样的事件：

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]]; 

我可以创建这样在同一天的另一事件：

[_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]]; 

和

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]]; 

我通过一个plist文件，其合作努力循环：然后我可以在不同的日子里，创建另一个事件获得所有事件以创建所有事件。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，只有最新的一个出现。我可以取出eventsArray = [[NSMutableArray alloc] init];这一行，但是新事件不仅会在正确的日期与其他事件一起出现，而且会在其他日子显示。所以，我想我可以在这样的事情抛来检查，如果我需要一个线，然后将事件添加到eventsDict但我得到-[CKCalendarEvent isEqualToDate:]: unrecognized selector sent to instance 0xc6bb880上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，我通过需要一种方式来循环plist，并确定程序何时需要在每个新事件上启动eventsArray。

您正在比较事件和日期。请参阅下面比较事件日期的代码。

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