This example shows an Objective-C networking client handling a login response, checking whether the received object is of type `KMLoginResponse` before casting it to access staff login details. The code defines a method `request:didReceiveResponse:` on a class inheriting from `KMRequest`, which releases the request, forwards the response to a delegate, and then verifies class membership using `isKindOfClass:`. The implementation relies on the `KMResponse` base class and delegate callbacks for asynchronous communication, though the conditional logic is flawed because it uses `isKindOfClass:` on the class object rather than the instance, preventing the cast from ever succeeding. The example originates from a gist by Caged.
