NSLog an object's memory address in overridden description method

Question

To print address use %p format specifier and self pointer:

-(NSString *) description {
    return [NSString stringWithFormat:@"<SomeClass: %p>\nparmeterOne: %@\nparameterTwo: %@",
            self, self.parameterOne, self.paramterTwo];
}

The easiest method is to use the super description

- (NSString *)description
{
    return [NSString stringWithFormat:@"%@ Area: %@, %@", [super description], self.identifier, self.name];
}

So in the case of this model object that is a subclass of NSObject, you can dodge extra work and remembering %p.

Manually using NSStringWithClass() and %p

- (NSString *)description
{
    return [NSString stringWithFormat:@"<%@: %p> Area: %@, %@", NSStringFromClass([self class]), self, self.identifier, self.name];
}

So in the case of an object model in which you have a concrete implementer that is derived from this class you will show the correct class name.
