please write follow bellow steps

In TableViewDidSelectRowAtIndexPath

 [[NSUserDefaults standardUserDefaults] setInteger:indexPath.row forKey:@"Checked"];
 [[NSUserDefaults standardUserDefaults] synchronize];

Now In CellForRowAtIndexPath

if(indexPath.row == [[NSUserDefaults standardUserDefaults]integerForKey:@"Checked"])
{
    cell.accessoryType = UITableViewCellAccessoryCheckmark;
}
else
{
    cell.accessoryType = UITableViewCellAccessoryNone;
}

It only CheckMarked the last value you have selected

you can use another class that is store your data and reload time you used that class and restore your data correctly and efficiently.

You need to store the last checked row index so you can load that value the next time you bring up the view controller. Since you appear to only have one section you just need to save (and restore) the row index. NSUserDefaults is a good place to store this NSInteger value. You can save the row index each time a new selection is made. You can load the current value in the view controller's viewDidLoad method.
