How to add Events from web service on calendar in Objective C

Question

I am new in iOS and I am facing problem regarding to show events on calendar.I am using JTCalendar https://github.com/chu888chu888/IOS-JTCalendar

My code is like this

In viewDidLoad

 _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];
//    }
//}

Its output is like this 02/06/2017 in array.How can I show it on calendar.

It is showing random events.But how can I show events on date?

Thanks in Advance!

You have commented function "createRandomEvents" in your source code.

This function defines your dates to be displayed on calendar.

Get events data from web service and you have to add dates in array "eventsByDate". Then you should be able to view dates.

Code: - (void)viewDidLoad { [super viewDidLoad];

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

}

In ScheduleKPI API response

[arrDates addObjectsFromArray:EndDatearrayScheduleKPI];

In ScheduleAudit API response

[arrDates addObjectsFromArray:EndDatearrayScheduleAudit];

In ScheduleMeeting API response

[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];
}
