Interception in the delete control panel in a UITableView

Question

I want to intercept the taps on the circular delete control ( an example of the delete control button ) on my TableView to find out when the “Delete” button comes in, and I can change the location of the cells. Can someone help me? thanks a lot!

Answer 1

You can handle the appearance of the Delete button if you subclass UITableViewCell and override the -willTransitionToState and / or -didTransitionToState there. How:

 - (void)willTransitionToState:(UITableViewCellStateMask)state{ if (state & UITableViewCellStateShowingDeleteConfirmationMask) // Delete button will appear }
