Instance Method

invalidateAndCancel

Cancels all outstanding tasks and then invalidates the session.

Declaration

- (void)invalidateAndCancel;

Discussion

Once invalidated, references to the delegate and callback objects are broken. After invalidation, session objects cannot be reused.

To allow outstanding tasks to run until completion, call finishTasksAndInvalidate instead.
