UITableView: can I delete multiple rows?

Question

I want to delete multiple rows from a table view, based on the user\'s selection. Obviously I can\'t use the didSelectRowAtIndexPath method because it will be calle

Answer 1

A late reply, but another way to handle this (if you are targeting iOS 5) is to toggle editing mode and use the built-in multiple cell selection. Easiest way to do this is to put this in viewDidLoad...

// add edit button to navigation bar, which auto toggles editing mode
self.navigationItem.rightBarButtonItem = self.editButtonItem;
// allows user to select multiple cells while in editing mode
self.tableView.allowsMultipleSelectionDuringEditing = YES;

See documentation for more details

Answer 2

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];
