Do I understand correctly that you want to know which animation the
animationDidStop:finished: refers to? Why not use the theAnimation parameter?
You can retain a reference to your two animations and do
if (theAnimation == dismissAnimation)
to choose the proper action.
BTW, terminology nit: "Delegate" refers to the object responding to the
callback methods, not to any action of a delegate, object using a delegate, or
any occurrence of setting a delegate object.
