我想按保存在 plist 中的日期标记我的日历

在此处输入图像描述

我把这段代码放在marksFromDate里面

- (NSArray*)calendarMonthView:(TKCalendarMonthView *)monthView marksFromDate:(NSDate *)startDate toDate:(NSDate *)lastDate
{        
    NSString *documentDirectory = [self applicationDocumentsDirectory];
    NSString *path = [documentDirectory stringByAppendingPathComponent:@"PlainNotes.plist"];
    NSMutableArray *tmpArray = [[NSMutableArray alloc] initWithContentsOfFile:path];
    self.Notes = tmpArray;
    NSString *date = [tmpArray valueForKey:@"CDate"];

    NSArray *data = [NSArray arrayWithObject:date];
    NSLog(@"Mark for this date %@", data);

    // 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];
    }


    return [NSArray arrayWithArray:marks];
}

这是用于日志

2012-08-19 17:10:50.168 PlainNotes[2852:f803] Mark for this date (
        (
        "2012-08-19 00:00:00 +0000",
        "2012-08-31 00:00:00 +0000"
    )
)

这没有标记我的日历，但下面的代码来自 TapkuCalendar

- (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", @"2011-01-09 00:00:00 +0000", @"2011-01-22 00:00:00 +0000",

    NSLog(@"Mark for this date %@", data);

我在这里看到的是我的，TapkuCalendar 日志是一样的，但为什么我的代码不能标记日历？如何解决？谢谢你。

该方法被定义为-(NSArray*)...所以我最初担心的是你没有返回任何东西。

尝试添加return data;到calendarMonthView:marksFromDate:toDate:. `

我已经解决了。我将 NSString 更改为 NSArray ，如下面的代码。

NSArray *data = [Notes valueForKeyPath:@"CDate"];
NSLog(@"Mark for this date %@", data);

谢谢大家的帮助。我真的很感激。对不起我的愚蠢问题。我只是一个新手。
