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 UITableView controller. 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

try

[[tableView scrollView] setDelegate:self];

You may get a warning that says tableView doesn't respond to scrollView, but it might work?

Answer 2

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.

Answer 3

for(int i=0;i<[[tableView subviews]count];i++){ if ([[[tableView subviews]objectAtIndex:i]isKindOfClass:[UIScrollView class]]) { [[[tableView subviews]objectAtIndex:i]setDelegate:self]; } }

Answer 4

Now UITableViewDelegate conforms to UIScrollViewDelegate !

(I write this answer because many people are going to find this page googling..)

Answer 5

UITableDelegate will implement UIScrollViewDelegate also.
