Question

Quick one. I’m overlooking something…

I have a grouped table view that is built from arrays in an NSDictionary. Each array is a section of the table. When in editing mode and a user clicks "delete" I call

- (void)removeObject:(MyClass *)myObject 

how can i determine which array to send the message [myArray removeObject:myObject]? NSDictionary doesn’t have an indexOfObject: method but NSArray does. I suppose I could iterate through each array looking for said object but that doesn’t seem right.

You could implement the standard UITableView protocols and use this method:

(void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle<br> forRowAtIndexPath:(NSIndexPath *)indexPath {
     <br><br>//check the section according to your array, if(indexPath.section ==....
     <br><br>
    if(editingStyle == UITableViewCellEditingStyleDelete) {
     <br>
    [arrayFoundBefore removeObjectAtIndex:indexPath.row];
    <br> 
    }
    <br>}

I think that’s the way to do it, not sure though. Can anyone clarify?
