我正在尝试让 Tapku 日历库在我的应用程序中处理核心数据。我已经设置了日历，但我现在要做的是让点标记显示保存在我的核心数据中的日期。

我正在尝试遵循此示例（http://developinginthedark.com/posts/iphone-tapku-calendar-markers），但在将其与核心数据混合时我被卡住了。

我需要使用的方法是：

- (NSArray*)calendarMonthView:(TKCalendarMonthView *)monthView marksFromDate:(NSDate *)startDate toDate:(NSDate *)lastDate {    
    NSLog(@"calendarMonthView marksFromDate toDate");   
    NSLog(@"Make sure to update 'data' variable to pull from CoreData, website, User Defaults, or some other source.");
    // When testing initially you will have to update the dates in this array so they are visible at the
    // time frame you are testing the code.
    NSArray *data = [NSArray arrayWithObjects:
                     @"2011-01-01 00:00:00 +0000", @"2011-12-01 00:00:00 +0000", nil]; 


    // Initialise empty marks array, this will be populated with TRUE/FALSE in order for each day a marker should be placed on.
    NSMutableArray *marks = [NSMutableArray array];

    // Initialise calendar to current type and set the timezone to never have daylight saving
    NSCalendar *cal = [NSCalendar currentCalendar];
    [cal setTimeZone:[NSTimeZone timeZoneForSecondsFromGMT:0]];

    // Construct DateComponents based on startDate so the iterating date can be created.
    // Its massively important to do this assigning via the NSCalendar and NSDateComponents because of daylight saving has been removed 
    // with the timezone that was set above. If you just used "startDate" directly (ie, NSDate *date = startDate;) as the first 
    // iterating date then times would go up and down based on daylight savings.
    NSDateComponents *comp = [cal components:(NSMonthCalendarUnit | NSMinuteCalendarUnit | NSYearCalendarUnit | 
                                                    NSDayCalendarUnit | NSWeekdayCalendarUnit | NSHourCalendarUnit | NSSecondCalendarUnit) 
                                          fromDate:startDate];
    NSDate *d = [cal dateFromComponents:comp];

    // Init offset components to increment days in the loop by one each time
    NSDateComponents *offsetComponents = [[NSDateComponents alloc] init];
    [offsetComponents setDay:1];    


    // for each date between start date and end date check if they exist in the data array
    while (YES) {
        // Is the date beyond the last date? If so, exit the loop.
        // NSOrderedDescending = the left value is greater than the right
        if ([d compare:lastDate] == NSOrderedDescending) {
            break;
        }

        // If the date is in the data array, add it to the marks array, else don't
        if ([data containsObject:[d description]]) {
            [marks addObject:[NSNumber numberWithBool:YES]];
        } else {
            [marks addObject:[NSNumber numberWithBool:NO]];
        }

        // Increment day using offset components (ie, 1 day in this instance)
        d = [cal dateByAddingComponents:offsetComponents toDate:d options:0];
    }

    [offsetComponents release];

    return [NSArray arrayWithArray:marks];
}

有一个像 TKCalendarMonthView 这样的类，根据您从核心数据中给出的数组，检查将显示点。您的核心数据中的日期数组将与您在日历中显示的特定月份的日期进行比较，如果两个日期都匹配，则 BOOL 将返回，因为它将标有“.”..

您可以使用以下方法做到这一点：

     - (void) generateDataForStartDate:(NSDate*)start endDate:(NSDate*)end
        {

                 //just check the condition according to you...It;s your logic that would work
                 if([datestring isEqualToString:strtemp])
                    {
                        Done=YES;
                        [dataDictionary setObject:str forKey:d];//USed to show the data
                        [dataArray addObject:[NSNumber numberWithBool:YES]]; // This array would store the place where you need to set the Dot in Calender
                        j=1;
                    }
        // This is the logic for not setting the DOT
         if(j==0){
            [dataArray addObject:[NSNumber numberWithBool:NO]];
                }

        TKDateInformation info = [d dateInformation];
        info.day++;
        Done=NO;
        d = [NSDate dateFromDateInformation:info];
        if([d compare:end]==NSOrderedDescending) break;


        }

希望这能解决您的问题....否则您可以自己设置 [dataArray addObject:[NSNumber numberWithBool:NO]]; 根据您的情况选择是/否。
