aspect_deregisterTrackedSelector

[hejunm]

In aspect_deregisterTrackedSelector(id self, SEL selector){} method,
after perform the code below,

if (tracker.selectorNames.count == 0 && tracker.selectorNamesToSubclassTrackers) {
     [swizzledClassesDict removeObjectForKey:currentClass];
 }

aspect can't promise " A method can only be hooked once per class hierarchy."
I think the code should be:

 if (tracker.selectorNames.count == 0 && tracker.selectorNamesToSubclassTrackers.count == 0) {
    [swizzledClassesDict removeObjectForKey:currentClass];
 }
