Hi,

Look at this code:

myUserInfo = [self.pUserIDDict objectForKey: theUserInfo.pUserID];
if (myUserInfo != nil)
        {
        LTWAssertAlways(@"myUserInfo - Dupe ID!!!!!!!!!!");
        }

if (theUserInfo.pUserID != nil)                                                 
                                        //Remove this Line for Warning
        [self.pUserIDDict setObject: theUserInfo forKey: theUserInfo.pUserID];  
        //Warning on this line!
} 


I get a warning saying that Key argument for setObjectForKey cannot be nil? I 
am wondering why it suddenly started moaning about this here and not other 
places were it is used and could be nil, like this:

myUserInfo = [self.pUserIDDict objectForKey: theUserInfo.pUserID];

This is the only place I’ve seen this warning and I’m using keys that could be 
nil in lots of places (without any problems as I obviously make sure that I 
don’t pass a nil…..

All the Best
Dave
