Question

在iPhone上基于闹钟的应用程序中，我使用的是tinyfool的TdCalenderView代码。我在日历中调用setDayFlag：day在drawDateWords方法中设置警报的日期。触发日期打开警报列表相应的日期。现在，我也在同一个应用程序中使用Tab栏。点击标签栏的项目0我显示包含日历的视图，点击项目1我显示了要写入和保存笔记的视图。当我写一个笔记并保存它时，我希望在相应的日期绘制一个点。但它没有发生。点不存在。但是当我点击日期时，点出现，第二次点击列表显示。这是我的代码：

appdelegate.m

calendar=[[TdCalendarView alloc]init];

包含标签栏的视图

这是标签项标签的切换案例，基于我显示和隐藏视图

       switch (tag) {

            case 0:

                WriteANoteView.hidden=YES;

                RecordANoteView.hidden=YES;

                BirthdayView.hidden=YES;

                AllNotesView.hidden=NO;

                app.calendar initCalView];

                [app.calendar drawDateWords];
                            break;

TdCalendarView.m

        -(void)initCalView{

        currentTime=CFAbsoluteTimeGetCurrent();

    currentMonthDate=CFAbsoluteTimeGetGregorianDate(currentTime,CFTimeZoneCopyDefault());

        currentMonthDate.day=1;

        currentSelectDate.year=0;

        monthFlagArray=malloc(sizeof(int)*93);

        [self clearAllDayFlag]; 

         app=(Note_TakerAppDelegate *)[[UIApplication sharedApplication] delegate];

        [app getWrittenNotesAndDates];

        app.calendar.tableContentArray=[[NSMutableArray alloc]init];

        app.calendar.tableRDatesArray=[[NSMutableArray alloc]init];

        app.calendar.tableCrDatesArray=[[NSMutableArray alloc]init];


    }


    -(void)drawDateWords{
        CGContextRef ctx=UIGraphicsGetCurrentContext();
        int width=self.frame.size.width;

        int dayCount=[self getDayCountOfaMonth:currentMonthDate];
        int day=0;
        int x=0;
        int y=0;
        int s_width=width/7;
        int curr_Weekday=[self getMonthWeekday:currentMonthDate];
        UIFont *weekfont=[UIFont boldSystemFontOfSize:12];





        for(int i=1;i<dayCount+1;i++)
        {

            day=i+curr_Weekday-2;
            x=day % 7;
            y=day / 7;
            NSString *date=[[[NSString alloc] initWithFormat:@"%2d",i] autorelease];
    [date drawAtPoint:CGPointMake(x*s_width+15,y*itemHeight+headHeight)withFont:weekfont];
            NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];

            for(int j=0;j<[app.datesofTextArray count];j++)
            {   

                if([[NSString stringWithFormat:@"%@",[app.datesofTextArray objectAtIndex:j]] length] !=0)
                {


                [dateFormatter setDateFormat:@"dd/MM/yyyy hh:mm:ss"];
                NSDate *dateFromString=[dateFormatter dateFromString:[NSString stringWithFormat:@"%@",[app.datesofTextArray objectAtIndex:j]]];
                [dateFormatter setDateFormat:@"dd"];
                int day1=[[dateFormatter stringFromDate:dateFromString]intValue];
                [dateFormatter setDateFormat:@"MM"];
                int month1=[[dateFormatter stringFromDate:dateFromString]intValue];
               [dateFormatter setDateFormat:@"yyyy"];
                int year1=[[dateFormatter stringFromDate:dateFromString]intValue];
                if(day1==day && month1==currentMonthDate.month && year1==currentMonthDate.year)
                {
                    NSLog(@"in if rdate day1=%d,month1=%d,year1=%d",day1,month1,year1);  
                    [self setDayFlag:day flag:1];
                    [self paintDot:day];

                }
            }
            else
            {
                //NSLog(@"in else date=%@",[app.datesofTextArray objectAtIndex:i]);

                [dateFormatter setDateFormat:@"dd/MM/yyyy hh:mm:ss"];
                NSDate *dateFromString=[dateFormatter dateFromString:[NSString stringWithFormat:@"%@",[app.creationDates objectAtIndex:j]]];
                [dateFormatter setDateFormat:@"dd"];
                int day1=[[dateFormatter stringFromDate:dateFromString]intValue];
                [dateFormatter setDateFormat:@"MM"];
                int month1=[[dateFormatter stringFromDate:dateFromString]intValue];
                [dateFormatter setDateFormat:@"yyyy"];
                int year1=[[dateFormatter stringFromDate:dateFromString]intValue];
                if(day1==day && month1==currentMonthDate.month && year1==currentMonthDate.year)
                {
                    NSLog(@"in if cdate day1=%d,month1=%d,year1=%d",day1,month1,year1);
                    [self setDayFlag:day flag:1];
                    [self paintDot:day];
                }


            }

        }

        [dateFormatter release];

        CGContextSetRGBFillColor(ctx, 0, 0, 0, 1);

    }


}

我不明白为什么会发生这种情况。非常感谢任何帮助。

好的。这可能听起来像是一个黑客但最终有效。我在显示日历视图和[TdCalenderView movePrevMonth]之前调用日历视图和[TdCalenderView movePrevMonth]之后显示日历视图，其中有一个标志来管理在Tab栏调用方法时取消动画。它刷新了我的日历并解决了问题。
