Remove the Dealloc method to notify the viewer to bring crash

The crash risk exists when the notification message in the Nsnotificationcenter has been emitted, while the Watcher object Child thread is released, that is, the thread that throws the notification message and the thread that is freed by the Watcher object child thread is inconsistent. The reason is that nsnotificationcenter is not thread-safe.

Workaround: Remove the notification as soon as possible or ensure that the release and throw notifications are on the same thread.
