Re: [iPhone] How to scroll to UITableView footer view
contentSize is the correct way to do this. It gives a ‘buffer zone’ at the top and bottom (and sides if you wish) on the scroll view.

Re: [iPhone] How to scroll to UITableView footer view
if by footer view, you mean content that is at the end of a table view, I suggest you read the UIScrollView Guide, specifically the issues regarding contentOffset.

Re: [iPhone] How to scroll to UITableView footer view
What about making the rect your view's actual bounds. Something like... CGRect footerBounds = [footerView bounds]; CGRect footerRectInTable = [tableView convertRect:footerBounds fromView:footerView]; [tableView scrollToRect:footerRectInTable animated:YES]; This should scroll to the footer view since you are basing it on the footer view's current bounds after you call endUpdate. If all is added and adjusted.

[tableview beginUpdates]; [tableview insertRowsAtIndexPaths:[NSArray arrayWithObject:[NSIndexPath indexPathForRow:(chatMessages.count - 1) inSection:0]] withRowAnimation:UITableViewRowAnimationLeft]; [tableview endUpdates]; if (tableview.tableFooterView) [tableview scrollRectToVisible:CGRectMake(0, tableview.contentSize.height+64, 320, 44) animated:YES]; Tharindu Madushanka ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

What success do you have with -[UIScrollView scrollRectToVisible:animated:], using a CGRect calculated from the scroll view's contentSize? UITableView is a UIScrollView. Always look for the properties and methods of the superclasses. — F ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: [iPhone] How to scroll to UITableView footer view
UITableView is a subclass of UIScrollView. So, you can ask for its contentSize and then call scrollRectToVisible:animated: with a rect that lies at the end of the contentSize.

[iPhone] How to scroll to UITableView footer view
Hi, How can I scroll to a UITableView footer all the time, while adding cells to table view content. Is there some way similar to scrollToRowAtIndexPath: , to scroll directly into my bottom footer view after adding new cells ?
