| I'm currently following the RaiseMan example through in the Cocoa Programming for Mac OS X book (Aaron Hillegass) and I'm currently up to Chapter 8 on Archiving.
I have a Delete button on the form which is connected to the remove: selector on an instance of ArrayController.
Although the Delete button seems to do what it is supposed to (remove items from the list next to it), I see messages like these appear in the debugger console:
2007-11-07 21:15:35.692 RaiseMan[543:10b] *** -[NSCFNumber <null selector>]: unrecognized selector sent to instance 0x110e50
Any ideas how to go about troubleshooting these sorts of messages? I tried poking around with gdb on the command line to see if I could find out what was sitting at the supplied address, without success. Why should I be getting messages like these if I set up the connections in Interface Builder?
thanks,
Andrew |
