[super setEditing:NO animated:NO];
[Table setEditing:NO animated:NO];
[Table reloadData];
[self.navigationItem.leftBarButtonItem setTitle:@"Edit"];
        [self.navigationItem.leftBarButtonItem setStyle:UIBarButtonItemStylePlain];
}
else

[self.navigationItem.leftBarButtonItem setStyle:UIBarButtonItemStyleDone];

If I am not wrong then you want to delete the cell of the tableView when delete button is clicked....

You need to call one other method of tableview:

//To Delete the Data - (void)setEditing:(BOOL)editing animated:(BOOL)animated { // Updates the appearance of the Edit|Done button as necessary. [super setEditing:editing animated:animated]; [tblViewBM setEditing:editing animated:YES]; // Disable the add button while editing. }

• (void)tableView:(UITableView *)tableView commitEditingStyle: (UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {

  if (editingStyle == UITableViewCellEditingStyleDelete) {

//Use your Array from which you need to delete the data. NSMutableDictionary *dict=(NSMutableDictionary *)[appDel.BookMarkAry objectAtIndex:indexPath.row]; type=[dict valueForKey:@"type"];

[appDel.BookMarkAry removeObjectAtIndex:indexPath.row];

[tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];

[tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade]; } }

I am sure this will Definately help you to delete the cell with data from array also.
