Question

I am pretty sure I am just missing the point here and getting confused. Can anyone tell me how I might write a simple description for an object that will print out the value of its instance variables to the console.

Also: is there anyway to present the information as a block (i.e. if you had 10 iVars its going to be a pain getting them all to return one by one)

@interface CelestialBody : NSObject {
    NSString *bodyName;
    int bodyMass;
}

- (NSString *)description { 
    return (@"Name: %@ Mass: %d", bodyName, bodyMass);
}

cheers -gary-

Answer 1

- (NSString*)description
{
  return [NSString stringWithFormat:@"Name: %@\nMass: %d\nFoo: %@",
     bodyName, bodyMass, foo];
}
