Table View problem...plz help...!!

Question

hi Frnz,

i want to delete multiple rows from a table view based on users selection.obviously i cant use didSelectRowAtIndexPath method coz it will be called for every row selected. i want to allow user to select multiple rows for deletion and then delete them in one go...Is it possible if yes then how to go about it.Also i am using a single view based project and i want the header of table view changed to "Delete" on the same view when the user want to delete the rows from the view.

Thx

You can do something this way:

- (void)tableView:(UITableView *)theTableView
      didSelectRowAtIndexPath:(NSIndexPath *)newIndexPath {

[theTableView deselectRowAtIndexPath:[theTableView indexPathForSelectedRow] animated:NO];
UITableViewCell *cell = [theTableView cellForRowAtIndexPath:newIndexPath];
if (cell.accessoryType == UITableViewCellAccessoryNone) {
    cell.accessoryType = UITableViewCellAccessoryCheckmark;
    [selectedCellsMutableArray addObject:newIndexPath];
} else if (cell.accessoryType == UITableViewCellAccessoryCheckmark) {
    cell.accessoryType = UITableViewCellAccessoryNone;
    [selectedCellsMutableArray removeObjectIdenticalTo:newIndexPath];
}

}

When user press Delete Selected button - just invoke something like

// change your model here and then:
[yourView deleteRowsAtIndexPaths:selectedCellsMutableArray withRowAnimation:UITableViewRowAnimationRight];
