Reload a table view's data without clearing its selection state

You can store the index path of the selected row with:

rowToSelect = [yourTableView indexPathForSelectedRow];

Before reload the data. And after reload use:

[yourTableView selectRowAtIndexPath:rowToSelect animated:YES scrollPosition:UITableViewScrollPositionNone];

JeroVallis solution works for single selection table views. Based on his idea this is how I made it work with multiple selection:

NSArray *selectedIndexPaths = [self.tableView indexPathsForSelectedRows];
[tableView reloadData];
for (int i = 0; i < [selectedIndexPaths count]; i++) {
    [tableView selectRowAtIndexPath:selectedIndexPaths[i] animated:NO scrollPosition:UITableViewScrollPositionNone];
}

The most efficient way is to keep the selected state in the data model

• Add a boolean property isSelected in the struct or class which represents the data source.
• In cellForRowAt set the selected state of the cell according to the property.
• In didSelectRow toggle isSelected in the data source item and reload only the particular row at the given index path.
