自动移除订阅 about glpubsub

[allenhsu]

理论上可以通过 Category 在所有 dealloc 方法中都主动 unsubscribeAll

是的，修改方案有多种，我想应该放到GLPubSub中统一处理，你看下一下方法是否可行？

• (id)subscribe:(NSString *)eventName obj:(id)obj handler:(GLEventHandler)handler {
  weak __typeof(self) weakSelf = self;
  id observer = [[NSNotificationCenter defaultCenter] addObserverForName:eventName object:obj queue:_pubSubQueue usingBlock:^(NSNotification *note) {
  if ( nil != weakSelf ) {
  __strong typeof(weakSelf) strongSelf = weakSelf;
  GLEvent *event = [[GLEvent alloc] initWithName:eventName obj:note.object data:[note.userInfo objectForKey:kGLPubSubDataKey]];
  handler(event);
  }
  }];
  NSMutableDictionary *subscriptions = (NSMutableDictionary *)objc_getAssociatedObject(self, &kGLPubSubSubscriptionsKey);
  if (!subscriptions) {
  subscriptions = [[NSMutableDictionary alloc] init];
  objc_setAssociatedObject(self, &kGLPubSubSubscriptionsKey, subscriptions, OBJC_ASSOCIATION_RETAIN_NONATOMIC);
  }
  NSMutableSet *observers = [subscriptions objectForKey:eventName];
  if (!observers) {
  observers = [[NSMutableSet alloc] init];
  [subscriptions setObject:observers forKey:eventName];
  }
  [observers addObject:observer];
  return observer;
  }

用上面方法实现存在，通知一直没有被移除，执行block不在调用，在Category中调用主动 unsubscribeAll会更好，改方法有打算做Pod库的更新吗？
