I know that a subclass of UITableViewCell can implement willTransitionToState and execute custom code at the time of transition. But is there any way t

    For iOS 6, here's my solution:

    Works for any of the transition states AND handles the swipe to delete gesture as well. Place this code in your subclass of UITableviewCell.

    - (void)willTransitionToState:(UITableViewCellStateMask)state {
    
        [super willTransitionToState:state];
    
        if (state == UITableViewCellStateDefaultMask) {
    
            NSLog(@"Default");
            // When the cell returns to normal (not editing)
            // Do something...
    
        } else if ((state & UITableViewCellStateShowingEditControlMask) && (state & UITableViewCellStateShowingDeleteConfirmationMask)) {
    
            NSLog(@"Edit Control + Delete Button");
            // When the cell goes from Showing-the-Edit-Control (-) to Showing-the-Edit-Control (-) AND the Delete Button [Delete]
            // !!! It's important to have this BEFORE just showing the Edit Control because the edit control applies to both cases.!!!
            // Do something...
    
        } else if (state & UITableViewCellStateShowingEditControlMask) {
    
            NSLog(@"Edit Control Only");
            // When the cell goes into edit mode and Shows-the-Edit-Control (-)
            // Do something...
    
        } else if (state == UITableViewCellStateShowingDeleteConfirmationMask) {
    
            NSLog(@"Swipe to Delete [Delete] button only");
            // When the user swipes a row to delete without using the edit button.
            // Do something...
        }
    }
