IPhone, an object on a picket sheet, how can I determine when an action sheet is closed / fired?

Question

How can I determine when an action sheet is closed or has been fired?

I followed this topic Installing UIDatePicker in a UIActionSheet and added a selection view to the action sheet. However, the didSelectRow event is raised while the action sheet is still open.

I want to update some data in my table view by changing some sql and re-querying my databases, but when updating every click slowly, I want to update when the action sheet is gone?

Answer 1

. (, actionSheet: didDismissWithButtonIndex: delegate)
