When my table view controller transitions to and from editing mode, I want to replace some cells in my table view. To do this, I override -setEditing:animated: to send -reloadRowsAtIndexPaths:withRowAnimation: to my table view.
The first time I swipe to delete a row in the table view, this works. My table view controller is asked for a new cell at the given index path (though the row animates incorrectly when canceling delete mode). But on subsequent occasions, the rows at the indexes passed to -reloadRows... simply vanish, and my view controller is never asked to provide new cells.
-
Build and run the attached demo app.
-
Swipe to enter delete mode on any of the numbered rows. Note that the first row changes background color.
-
Cancel delete mode by tapping elsewhere. Note that the first row animates incorrectly.
-
Swipe to delete any of the numbered rows again.
First row changes background color again; log message indicates that the data source has been asked for a new cell at the 0th index.
First row disappears. No log message indicating the data source was asked for a new cell.
