Become UIScrollViewDelegate delegate for UITableView

Question

I have a UITableView instance variable. I want to be able to register my view controller to be the UIScrollViewDelegate for my UITableViewController. I have already tried

tableView.delegate = self;

But when scrolling, my methods

- (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView
- (void)scrollViewDidEndDragging:(UIScrollView *)scrollView            
                  willDecelerate:(BOOL)decelerate

don't get called. Any suggestions?

Answer 1

Now UITableViewDelegate conforms to UIScrollViewDelegate !

I don't think is NOW, is just that it is. – Enterectomy

It's NOW maybe because in 2009 UITableViewDelegate didn't conform to UIScrollViewDelegate ;) – Winonawinonah

Answer 2

UITableViewDelegate will implement UIScrollViewDelegate protocol also.

Answer 3

This is officially unsupported. UITableView and UIWebView do not expose their internally managed scrollviews.

You can descend into the subview hierarchy and make undocumented calls, but that's not recommended, as it's officially prohibited and can break under future OS versions if the underlying (undocumented) API changes.

I was afraid this was the case. Thanks. – Peroxidase

As santoni's answer below indicates, UITableViewDelegate conforms to UIScrollViewDelegate (this may have changed in an SDK release?), which means that all UIScrollViewDelegate messages will get passed to the UITableView's delegate. – Finnougric

a uitableview is a uiscrollview – Paucity
