I'm using FSCalendar in my app. I placed the searchbar, which works properly with tableview below the FSCalendar. I select any row in the table and go to the next viewcontroller to edit selected row. As soon as I returned to the main VC (with FSCalndar), my searchbar disappeared. I have the same searchbar with tableview in other VC (without FSCalendar), and it works properly every time. My code for FSCalendar, tableview and searchbar are below. Does anybody have any suggestions? Probably somebody faced with similar issue before? Thanks in advance!
