iOS – Ekcalendar did not appear in Calendar.App

EKSource *theSource = [eventStore defaultCalendarForNewEvents]. source;

I followed this answer: how do I create a new EKCalendar on iOS device?

But the calendar I created does not appear in the iPhone’s calendar.app? should be?

Maybe I’m a little confused?

The code is normal, I can record the calendar, etc…

I found another A simpler and possibly more powerful method.
Just use the default calendar source for the new calendar.

EKSource *theSource = [eventStore defaultCalendarForNewEvents]. source;
