NSLog an object's memory address in overridden description method

I am overriding an object's description method. I need to know how to print the object's memory address to replace *{???}* in the code below:

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

I want it to print in the console like this:

<SomeClass: 0x4c05600> parameterOne: 12 parameterTwo: sausages

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.
