// lots more code

Noob question: I'm putting together a small code library and I'm
trying to include some error checking in the methods; what I want to
protect against is the following:
NSNumber *myNum;
// Lots of code where I've forgotten to actually do anything with
myNum
results = [myClass someCalculationUsing: myNum];
myNum in this case is an object and does exist but it's not a valid,
usable argument. So in the implementation I'd like to have something
along the lines of:
if (myNum == nil)
NSLog(@"some error message");
but can't figure out what to check for that would get me into the
error message condition. Any suggestions?
