How do i call following method:

 - (void)tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath:(NSIndexPath *)indexPath

Answer 1

First thing to note here is that when you use custom accessoryView in a cell then the tableView:accessoryButtonTappedForRowWithIndexPath: delegate method would not be called. You have to add some target/action to the button you are adding as the custom accessory and handle the tap action yourself. You should add the custom accessory something like this,

UIButton *accessory = ...;
[accessory addTarget:self action:@selector(onCustomAccessoryTapped:) forControlEvents:UIControlEventTouchUpInside];
...
cell.accessoryView = accessory;

And in the onCustomAccessoryTapped: method you have to get the index path like this,

- (void)onCustomAccessoryTapped:(UIButton *)sender {

    UITableViewCell *cell = (UITableViewCell *)sender.superview;
    NSIndexPath *indexPath = [tableView indexPathForCell:cell];

    // Now you can do the following
    [self tableView:tableView accessoryButtonTappedForRowWithIndexPath:indexPath];

    // Or you can do something else here to handle the action
}
