I have a very simple application with a UITableViewController. Upon EDITING, I am trying to slide a row into position 0 of the first section. The new row should have an INSERT editing style while the existing row should have a DELETE style.
I've overridden the following 4 methods:
// Customize the number of rows in the table view.
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
if (self.editing && section == 0) {
return2;
return 1;
- (UITableViewCellEditingStyle)tableView:(UITableView*)tableView
editingStyleForRowAtIndexPath:(NSIndexPath*)indexPath {
int section = indexPath.section;
int row = indexPath.row;
if (self.editing && section == 0 && row == 0) {
return UITableViewCellEditingStyleInsert;
return UITableViewCellEditingStyleDelete;
- (void)setEditing:(BOOL)editing animated:(BOOL)animated {
[super setEditing:editing animated:animated];
NSIndexPath *ip = [NSIndexPath indexPathForRow:0 inSection:0];
[self.tableView beginUpdates];
if (editing) {
[self.tableView insertRowsAtIndexPaths:[NSArray arrayWithObject:ip]
withRowAnimation:UITableViewRowAnimationLeft];
} else {
[self.tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:ip]
withRowAnimation:UITableViewRowAnimationFade];
[self.tableView endUpdates];
// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"ClientsControllerCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc ] initWithStyle:UITableViewCellStyleValue1reuseIdentifier:CellIdentifier] autorelease];
int section = indexPath.section;
int row = indexPath.row;
if (self.editing && section == 0 && row == 0) {
cell.textLabel.text = @"Add Me";
cell.detailTextLabel.text = @"Detail text";
} else {
cell.textLabel.text = @"Test me";
cell.detailTextLabel.text = @"Detail text";
return cell;
But as soon as I go into EDIT mode, "both" cells end up with an editing style of UITableViewCellEditingStyleInsert.
If I change my logic and append the new cell to the END - then it correctly draws the cells with a DELETE style and the new cell get's an INSERT.
Either way, tableView:editingStyleForRowAtIndexPath gets invoked 4 times. In fact, if I insert the new cell into section:0 row:0, this method gets called with section:row 0:0, 0:1, 0:0, 0:0. Whereas if I append the new cell into section: row:1, this method gets called with section:row 0:0, 0:1, 0:0, 0:1.
What am I missing? I should be able to insert a row and catch it right? For some reason, I can't see section=0 row=1 come through a second time.

There's another question on StackOverflow that appears to ask essentially the same thing:
SO 1508066
.
The answer there claims it's nonstandard to put the Insert row at the top; it should go at the bottom instead. I'm not sure I agree with that contention, but it's certainly the path of least resistance.
