NSView does not exist on the iPhone, as it uses Cocoa-Touch and not Cocoa.

If you want to get notifications about a UITableView‘s scroll events, just implement the UIScrollView delegate. It’s documented here.

The delegate method you’ll want to use is this one:

- (void)scrollViewDidScroll:(UIScrollView *)scrollView{

}

There are other handy methods in there though, like:

- (void)scrollViewDidEndZooming:(UIScrollView *)scrollView 
                       withView:(UIView *)view
                        atScale:(float)scale{

}
