Answer 1

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.
