I'm using an Array Controller's Add method wired to a button to enable text
data entries into a table. How do I set the table to activate it's top row
when pressing the Add button in preparation for input? At this point if the
table contains many rows of data and the user clicks the Add button the
table's lowest row activates. The user is forced to scroll down to the very
bottom of the table prior to entry


int row = [a indexOfObjectIdenticalTo:p];
[tableView editColumn:0 row:row withEvent:nil select:YES];
a = your array controller/arrary
p = object added


The OP asked for the item to be added at the top, so that doesn't help...


You need to make sure you insert the new object at the right place in the array controller's arranged objects.
One approach is to implement a new action method in your document/ application controller:


- (IBAction)newAtTop:sender {

    id newObject = [arrayController newObject];
    [arrayController insertObject:newObject atArrangedObjectIndex:0];
    [tableView editColumn:0 row:0 withEvent:nil select:YES];
    [newObject release];
}
