Hey Steve,
In this case, you are returning a regular integer (count returns just
a regular, scalar type). But you've declared your return value as id,
which is a typedef for a type of pointer. You either have to return an
actual integer, or wrap the return of count in an object like NSNumber.

Hi folks, newbie here.
A quickie query on a warning.
Both returns in the following code give a 'warning: return makes
pointer from integer without cast'
- (id)outlineView:(NSOutlineView *)outlineView
numberOfChildrenOfItem:(id)item
{
if (!item) {
return [outlineTree count];
}
return [[outlineTree objectForKey:item] count];
I can't work out why. "count" returns an integer which I should be
able to return or does the return only send back a pointer to the
integer of which I should be casting earlier on?
