How do I debug this error: CFNOTIFICATIONCENTER_IS_CALLING_OUT_TO_AN_OBSERVER?

Question

I am getting an error in my app that I have no idea of how to figure out, has anyone seen this before:

#   Binary Image Name   Address Symbol
0   RepZio  0x002bd         


        

Answer 1

I know it's old question, but maybe I will help to someone.

In my case the same crash occurred when NSTextField in NSTableViewCell was in editing mode and user tried to select value from combobox outside of tableView without finishing editing. And the same CFNOTIFICATIONCENTER_... crash was on line [tableView reloadData].

So, my way to resolve crash was to put [self.window makeFirstResponder:nil] before reloading the table.
