ios - 如何在 Objective C 中的日历上添加来自 Web 服务的事件

Question

我是 iOS 的新手，我在日历上显示事件时遇到问题。我正在使用 JTCalendar https://github.com/chu888chu888/IOS-JTCalendar

我的代码是这样的

在viewDidLoad中

 _calendarManager = [JTCalendarManager new];
    _calendarManager.delegate = self;

    // Generate random events sort by date using a dateformatter for the demonstration
    //[self createRandomEvents];

    // Create a min and max date for limit the calendar, optional
    [self createMinAndMaxDate];

    [_calendarManager setMenuView:_calendarMenuView];
    [_calendarManager setContentView:_calendarContentView];
    [_calendarManager setDate:_todayDate];

#pragma mark - CalendarManager delegate

// Exemple of implementation of prepareDayView method
// Used to customize the appearance of dayView
- (void)calendar:(JTCalendarManager *)calendar prepareDayView:(JTCalendarDayView *)dayView
{
    // Today
    if([_calendarManager.dateHelper date:[NSDate date] isTheSameDayThan:dayView.date]){
        dayView.circleView.hidden = NO;
        dayView.circleView.backgroundColor = [UIColor blueColor];
        dayView.dotView.backgroundColor = [UIColor whiteColor];
        dayView.textLabel.textColor = [UIColor whiteColor];
    }
    // Selected date
    else if(_dateSelected && [_calendarManager.dateHelper date:_dateSelected isTheSameDayThan:dayView.date]){
        dayView.circleView.hidden = NO;
        dayView.circleView.backgroundColor = [UIColor redColor];
        dayView.dotView.backgroundColor = [UIColor whiteColor];
        dayView.textLabel.textColor = [UIColor whiteColor];
    }
    // Other month
    else if(![_calendarManager.dateHelper date:_calendarContentView.date isTheSameMonthThan:dayView.date]){
        dayView.circleView.hidden = YES;
        dayView.dotView.backgroundColor = [UIColor redColor];
        dayView.textLabel.textColor = [UIColor lightGrayColor];
    }
    // Another day of the current month
    else{
        dayView.circleView.hidden = YES;
        dayView.dotView.backgroundColor = [UIColor redColor];
        dayView.textLabel.textColor = [UIColor blackColor];
    }

    if([self haveEventForDay:dayView.date]){
        dayView.dotView.hidden = NO;
    }
    else{
        dayView.dotView.hidden = YES;
    }
}

- (void)calendar:(JTCalendarManager *)calendar didTouchDayView:(JTCalendarDayView *)dayView
{
    _dateSelected = dayView.date;

    // Animation for the circleView
    dayView.circleView.transform = CGAffineTransformScale(CGAffineTransformIdentity, 0.1, 0.1);
    [UIView transitionWithView:dayView
                      duration:.3
                       options:0
                    animations:^{
                        dayView.circleView.transform = CGAffineTransformIdentity;
                        [_calendarManager reload];
                    } completion:nil];


    // Don't change page in week mode because block the selection of days in first and last weeks of the month
    if(_calendarManager.settings.weekModeEnabled){
        return;
    }

    // Load the previous or next page if touch a day from another month

    if(![_calendarManager.dateHelper date:_calendarContentView.date isTheSameMonthThan:dayView.date]){
        if([_calendarContentView.date compare:dayView.date] == NSOrderedAscending){
            [_calendarContentView loadNextPageWithAnimation];
        }
        else{
            [_calendarContentView loadPreviousPageWithAnimation];
        }
    }
}

#pragma mark - CalendarManager delegate - Page mangement

// Used to limit the date for the calendar, optional
- (BOOL)calendar:(JTCalendarManager *)calendar canDisplayPageWithDate:(NSDate *)date
{
    return [_calendarManager.dateHelper date:date isEqualOrAfter:_minDate andEqualOrBefore:_maxDate];
}

- (void)calendarDidLoadNextPage:(JTCalendarManager *)calendar
{
    //    NSLog(@"Next page loaded");
}

- (void)calendarDidLoadPreviousPage:(JTCalendarManager *)calendar
{
    //    NSLog(@"Previous page loaded");
}

#pragma mark - Fake data

- (void)createMinAndMaxDate
{
    _todayDate = [NSDate date];

    // Min date will be 2 month before today
    _minDate = [_calendarManager.dateHelper addToDate:_todayDate months:-12];

    // Max date will be 2 month after today
    _maxDate = [_calendarManager.dateHelper addToDate:_todayDate months:12];
}

// Used only to have a key for _eventsByDate
- (NSDateFormatter *)dateFormatter
{
    static NSDateFormatter *dateFormatter;
    if(!dateFormatter){
        dateFormatter = [NSDateFormatter new];
        dateFormatter.dateFormat = @"dd-MM-yyyy";
    }

    return dateFormatter;
}

- (BOOL)haveEventForDay:(NSDate *)date
{
    NSString *key = [[self dateFormatter] stringFromDate:date];

    if(_eventsByDate[key] && [_eventsByDate[key] count] > 0){
        return YES;
    }
    return NO;
}

//- (void)createRandomEvents
//{
//    _eventsByDate = [NSMutableDictionary new];
//    
//    for(int i = 0; i < 30; ++i){
//        // Generate 30 random dates between now and 60 days later
//        NSDate *randomDate = [NSDate dateWithTimeInterval:(rand() % (3600 * 24 * 60)) sinceDate:[NSDate date]];
//        
//        // Use the date as key for eventsByDate
//        NSString *key = [[self dateFormatter] stringFromDate:randomDate];
//        
//        if(!_eventsByDate[key]){
//            _eventsByDate[key] = [NSMutableArray new];
//        }
//        
//        [_eventsByDate[key] addObject:randomDate];
//    }
//}

它的输出就像数组中的 02/06/2017 一样。如何在日历上显示它。

它显示的是随机事件。但是我怎样才能按日期显示事件呢？

提前致谢!

您在源代码中注释了函数“createRandomEvents”。

此函数定义要在日历上显示的日期。

从 Web 服务获取事件数据，您必须在数组“eventsByDate”中添加日期。然后你应该能够查看日期。

代码:-(无效)viewDidLoad { [ super viewDidLoad];

NSMutableArray *arrDates = [[NSMutableArray alloc] init];

在 ScheduleKPI API 响应中

[arrDates addObjectsFromArray:EndDatearrayScheduleKPI];

在 ScheduleAudit API 响应中

[arrDates addObjectsFromArray:EndDatearrayScheduleAudit];

在 ScheduleMeeting API 响应中

[arrDates addObjectsFromArray:EndDatearrayScheduleMeeting];

[self funAddEvents:arrDates];

- (void)funAddEvents:(NSArray *)arrDate
{
  eventsByDate = [NSMutableDictionary new];
  for(NSString *strDate in arrDate){

    NSDateFormatter *dateformat = [[NSDateFormatter alloc] init];
    [dateformat setDateFormat:@"YYYY/MM/dd"];
    NSDate *myDate = [dateformat dateFromString:strDate];
    NSString *key = [[self dateFormatter] stringFromDate:myDate];

    if(!eventsByDate[key]){
        eventsByDate[key] = [NSMutableArray new];
    }

    [eventsByDate[key] addObject:myDate];
}

[self.calendar reloadData];
}
