Events not showing on selecting date

[nitishrana28]

Everything works fine for current date but none of the events for other dates are displayed. My code:

- (NSArray *) calendarDayTimelineView:(TKCalendarDayView*)calendarDayTimeline eventsForDate:(NSDate *)eventDate{

NSLog(@"eventDate : %@",eventDate);
NSDateFormatter *formatter = [NSDateFormatter new];
[formatter setDateFormat:@"yyyy-MM-dd"];
[formatter setLocale:[NSLocale systemLocale]];
NSString *dateString = @"";
dateString = [formatter stringFromDate:eventDate];
NSMutableArray *arr = [[CommonModel shared] GetAllCustomerArticleDetailForDayCalendar:dateString];
NSDateComponents *info = [[NSDate date] dateComponentsWithTimeZone:calendarDayTimeline.calendar.timeZone];
info.second = 0;
NSMutableArray *ret = [NSMutableArray array];

for(CustomerArticleDetail *detail in arr)
{
    [formatter setDateFormat:@"yyyy-MM-dd'T'HH:mm:ss"];
    NSDate *dateStart = [formatter dateFromString:detail.StartDate];
    NSDate *dateEnd = [formatter dateFromString:detail.EndDate];
    [formatter setDateFormat:@"yyyy-MM-dd'T'hh:mm:ss"];
    NSString *start = [formatter stringFromDate:dateStart];
    NSString *end = [formatter stringFromDate:dateEnd];

    TKCalendarDayEventView *event = [calendarDayTimeline dequeueReusableEventView];
    if(event == nil) event = [TKCalendarDayEventView eventView];

    NSInteger col = arc4random_uniform(3);
    [event setColorType:col];

    event.identifier = [NSNumber numberWithInt:detail.Id];
    event.titleLabel.text = detail.CustomerName;
    event.locationLabel.text = detail.Article_Details;
    int hours = [[[[[start componentsSeparatedByString:@"T"] objectAtIndex:1] componentsSeparatedByString:@":"] objectAtIndex:0] intValue];
    int minutes = [[[[[start componentsSeparatedByString:@"T"] objectAtIndex:1] componentsSeparatedByString:@":"] objectAtIndex:1] intValue];
    info.hour = hours;
    info.minute = minutes;
    event.startDate = [NSDate dateWithDateComponents:info];

    hours = [[[[[end componentsSeparatedByString:@"T"] objectAtIndex:1] componentsSeparatedByString:@":"] objectAtIndex:0] intValue];
    minutes = [[[[[end componentsSeparatedByString:@"T"] objectAtIndex:1] componentsSeparatedByString:@":"] objectAtIndex:1] intValue];
    info.hour = hours;
    info.minute = minutes;
    event.endDate = [NSDate dateWithDateComponents:info];

    [ret addObject:event];
}

return ret;
}
