appDelegate.banks = [[NSArray alloc]initWithContentsOfFile:tempPath];

backButton = [[UIBarButtonItem alloc]initWithTitle:#"Back" style:UIBarButtonSystemItemCancel target:self action:#selector(closeSettingsView)];
navigationItem.leftBarButtonItem = backButton;

- (void)setEditing:(BOOL)editing animated:(BOOL)animated {
[super setEditing:editing animated:animated];
[banksTableView setEditing:editing animated:animated];
if (editing) {
addButton = [[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:#selector(addBankFromList)];
navigationItem.leftBarButtonItem = addButton;
} else {
navigationItem.leftBarButtonItem = backButton;
NSString *tempPath = [self getPathOfSettingsPlist];
self.picker.hidden = YES;
[appDelegate.banks writeToFile:tempPath atomically:YES];
}
}
- (void)addBankFromList {
// not interesting
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}
// Customize the number of rows in the table view.
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [appDelegate.banks count];
}
// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"BanksTableCell";
indexForPath = indexPath;
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:CellIdentifier] autorelease];
cell.selectionStyle = UITableViewCellEditingStyleNone;
}
cell.textLabel.text = [appDelegate.banks objectAtIndex:indexPath.row];
return cell;
}
// Override to support editing the table view.
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle) editingStyle: forRowAtIndexPath:(NSIndexPath *)indexPath {
if (editingStyle == UITableViewCellEditingStyleDelete) {
// Delete the row from the data source
[appDelegate.banks removeObjectAtIndex:indexPath.row];
[banksTableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationRight];
[banksTableView reloadData];
}
}
//// Override to support rearranging the table view.
- (void)tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath *)fromIndexPath toIndexPath:(NSIndexPath *)toIndexPath {
NSString *temp = [appDelegate.banks objectAtIndex:fromIndexPath.row];
[appDelegate.banks removeObjectAtIndex:fromIndexPath.row];
[appDelegate.banks insertObject:temp atIndex:toIndexPath.row];
}

Actually you have added an extra colon(":") in the commitEditingStyle: method name. Adding the extra colon has made this method a completely different method. So, your view controller thought that you haven't implemented the commitEditingStyle: method and didn't do anything while you edit your table view.
Just remove the colon(":") after editingStyle in the commitEditingStyle: method. That will fix the problem. That line should look like this,
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle) editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
