Remembering scroll position on UITableView


See here you have to first save the scrolled position of tableView i.e. contentOffset of tableView and then reuse it when you are coming back to tableView.

1)When and where you will save it :

When : At the point, when you are drilling down to detailViewController save the contentOffset of tableView

How : float verticalContentOffset = tableView.contentOffset.y;

2) How will you set tableView back to the same scrolled position :

[tableView setContentOffset:CGPointMake(0, verticalContentOffset)];

Hope this will help you.


Sorted!

With a bit of inspiration from Desdenova, whilst at work I had a good think about it and realised what it could be. Remembering that I had a search bar, I had implemented the following code a few months ago to hide it:

[self.tableView setContentOffset:CGPointMake(0,-20) animated:NO];

In naivety I put that in viewDidAppear rather than viewDidLoad. Obviously, this did hide the search bar, but with it being in the wrong void command it did it every time the masterDetailView returned to the top of the stack. So, after moving the above code to viewDidLoad it now still hides it, but only the once.

I'm just spelling it out like this for other beginners, like myself, who may come across the same problem and may just save their sanity!

Thanks to you all for your ideas that helped me out.

+1 to you all!


If anyone is wondering, I tried the solution by Prashant N and it worked. However reloadData don't actually reset the scroll position anymore now, so I didn't have to do anything other than reloadData.
