How to deselect a selected UITableView cell?

I am working on a project on which I have to preselect a particular cell.

I can preselect a cell using -willDisplayCell, but I can't deselect it when the user clicks on any other cell. 

- (void)tableView:(UITableView*)tableView 
        willDisplayCell:(UITableViewCell*)cell
        forRowAtIndexPath:(NSIndexPath*)indexPath
{ 
    AppDelegate_iPad *appDelegte = 
      (AppDelegate_iPad *)[[UIApplication sharedApplication] delegate];

    if ([appDelegte.indexPathDelegate row] == [indexPath row])
    {
        [cell setSelected:YES];    
    } 
}

- (void)tableView:(UITableView *)tableView 
        didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

    AppDelegate_iPad *appDelegte = 
      (AppDelegate_iPad *)[[UIApplication sharedApplication] delegate];

    NSIndexPath *indexpath1 = appDelegte.indexPathDelegate;
    appDelegte.indexPathDelegate = indexPath;
    [materialTable deselectRowAtIndexPath:indexpath1 animated:NO];
}

Can you help?

This is a solution for Swift 4 

 in tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath)

just add 

tableView.deselectRow(at: indexPath, animated: true)

it works like a charm

example: 

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        tableView.deselectRow(at: indexPath, animated: true)
//some code
}

Swift 4:

func tableView(_ tableView: UITableView, willSelectRowAt indexPath: IndexPath) -> IndexPath? {
    let cell = tableView.cellForRow(at: indexPath)
    if cell?.isSelected == true { // check if cell has been previously selected
        tableView.deselectRow(at: indexPath, animated: true)
        return nil
    } else {
        return indexPath
    }
}

Swift 3/4

In ViewController:

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
    tableView.deselectRow(at: indexPath, animated: true)
}

In Custom Cell:

override func awakeFromNib() {
    super.awakeFromNib()
    selectionStyle = .none
}

Swift 3.0:

Following the protocol conformance section of the ray wenderlich swift style guide, to keep related methods grouped together, put this extension below your view controller class like that:

// your view controller
class MyViewcontroller: UIViewController {
  // class stuff here
}

// MARK: - UITableViewDelegate
extension MyViewcontroller: UITableViewDelegate {
      // use the UITableViewDelegate method tableView(_:didSelectRowAt:)
    func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {

        // your code when user select row at indexPath

        // at the end use deselectRow
        tableView.deselectRow(at: indexPath, animated: true)
    }
