Let's say I have a class interface and implementation, as follows:

---
@interface A : NSObject {
   ...
}
- (void) handleTask;
@end

@implementation A
...
- (void) handleTask {
   // do stuff specific to A object type...
}
---

Let's say I then subclass A and override -handleTask:

---
@interface B : A {
   ...
}
- (void) handleTask;
@end

@implementation B
...
- (void) handleTask {
   // do stuff specific to B object type...
}
---

If I instantiate a variable of type B, is there a way to conditionally use the -handleTask method from either class A or B? For example, by casting to (A *) when calling -handleTask?

Apologies in advance, if this is a dumb question. Thanks for your advice.
