Popping UINavigationController to a UITableView and displaying a different selected row

I am creating an application with a UITableView being the first item on the stack of the UINavigationController that it's in. Making a selection on the UITableView will push the view to a "DetailedViewController". In the DetailedViewController, you can navigate through items that the table view is populated with.

When p开发者_如何学Copping the DetailedViewController, and moving back to the UITableView, how can I deselect the respective item that I've navigated to through the DetailedViewController and display it centered in the UITableView?

An example that everyone can see would be the Mail application. When you're in your inbox and make a selection, you push a "DetailedViewController". There, you can navigate through the items populated in the UITableView. When you pop the DetailedViewController, it deselects the respective item that you were looking at last in the DetailedViewController.

To deselect the selected row, write the following code viewDidAppear: method.

// Index path for selected row
NSIndexPath *selectedRow = [_tableView indexPathForSelectedRow];

// Deselet the row with animation
[_tableView deselectRowAtIndexPath:selectedRow animated:YES];

// Scroll the selected row to the center
[_tableView scrollToRowAtIndexPath:selectedRow 
       atScrollPosition:UITableViewScrollPositionMiddle 
               animated:YES];

Depending on how you want the animation to look you could simply deselect your currently selected row.

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
     [tableView deselectRowAtIndexPath:indexPath animated:YES];
     ...
}
