iOS Question Tableview: check if actionbuttons-menu is open

[schimanski]

Is it possible to check, if an actionbutton-menu of a tableview-cell is still opened?
In my projekt, I update the tableview every 3 seconds. If the actionbuttons are shown, they will be closed each time, the tableview is updated.

I now want to stop the update-timer as long as the actionsbuttons are shown.
