Event indicator is sometimes not displayed.

[KatrinLomp]

When navigating between months, I sometimes don't see indicator on dates that should have events. I tried this on versions 2.2.0 and 2.1.1. With 2.1.1 I see indicator, but the color is not what I return in calendar:appearance:eventColorsForDate:. With 2.2.0 I don't see any indicator (maybe clear color is used?).

I tried to get an example to reproduce the problem. This is the setup, that currently reproduces the problem for me:

• (NSInteger)calendar:(FSCalendar *)calendar numberOfEventsForDate:(NSDate *)date {
  NSCalendar *gregorian = [[NSCalendar alloc] initWithCalendarIdentifier:NSCalendarIdentifierGregorian];
  NSDateComponents *comp = [gregorian components:(NSCalendarUnitYear | NSCalendarUnitMonth | NSCalendarUnitDay) fromDate:date];
  if ((comp.year == 2016 && comp.month == 05 && comp.day == 26)
  || (comp.year == 2016 && comp.month == 06 && comp.day == 01)
  || (comp.year == 2016 && comp.month == 06 && comp.day == 23)
  || (comp.year == 2016 && comp.month == 06 && comp.day == 24)
  || (comp.year == 2016 && comp.month == 06 && comp.day == 25)
  || (comp.year == 2016 && comp.month == 07 && comp.day == 01)
  || (comp.year == 2016 && comp.month == 07 && comp.day == 07)
  || (comp.year == 2016 && comp.month == 07 && comp.day == 18)) {
  return 1;
  }

  return 0;
  }

• (NSArray *)calendar:(FSCalendar *)calendar appearance:(FSCalendarAppearance *)appearance eventColorsForDate:(NSDate *)date {
  return @[[UIColor yellowColor]];
  }

I just switch between these months and sometimes indicator goes missing. I don't know if this matters, but I have a small delay before I load events for new month. I prepare events for new month while calendar animates from one month to another and once it's done animating, I reload calendar.

Hi @KatrinLomp . Can u try the latest?

[KatrinLomp]

I'm still able to reproduce it.

[WenchaoD]

Can u make a demo and share it.

[KatrinLomp]

I created demo project here: https://github.com/KatrinLomp/EventIndicatorDemo
I was not able to reproduce it with default calendar appearance, so I made it match the setting I used in my app. For reproducing I first scroll forward to August and then go back to April. While scrolling back and forth between these, you should notice, that sometimes some indicators are not displayed.

Haven't been able to reproduce with latest code. Thank you for the fix!
