How to make a cell on a UITableView not selectable?

I have a cell that I am inserting to the top of a UITableView. How can I make sure that when the user clicks on the cell, it doesn't show the blue selected indicator?

To remove the ability of selecting any table cells, or particular table cells based on the row index, use willSelectRowAt

func tableView(_ tableView: UITableView, willSelectRowAt indexPath: IndexPath) -> IndexPath? {


        return nil
    }

To simply remove the UI effect of selecting the element, set the selection style of the UITableViewCell to UITableViewCellSelectionStyleNone

Swift 5:

selectionStyle = .none

To make a cell completely non-selectable on a per-cell basis two things are required:

1- As others said:

cell.selectionStyle = UITableViewCellSelectionStyleNone;

2- Implement this delegate method as follows:

// Called before the user changes the selection. Return a new indexPath, or nil, to change the proposed selection.
- (NSIndexPath *)tableView:(UITableView *)tableView willSelectRowAtIndexPath:(NSIndexPath *)indexPath{
    UITableViewCell* cell = [tableView cellForRowAtIndexPath:indexPath];
    if(cell.selectionStyle == UITableViewCellSelectionStyleNone){
        return nil;
    }
    return indexPath;
}

From the Storyboard set the following for the Table View:

Selection: No Selection

Show Selection On Touch: False

you can do

cell.selectionStyle = UITableViewCellSelectionStyleNone;

for Swift 3 you can use

 cell.isUserInteractionEnabled = false

Swift Syntax:

cell.selectionStyle = UITableViewCellSelectionStyle.None

I am answering from point of view of disabling TableViewCell. You can use the storyboard.

XCode Version 8.2.1 (8C1002)

Select the TableVewCell on storyboard and following will be visible on the right side panel - Utilities.

Make the Selection: None

That's all!

The question was how to make certain cells selectable and others not. This was my solution, (after trying lots of other suggestions):

func tableView(_ tableView: UITableView, willSelectRowAt indexPath: IndexPath) -> IndexPath? {
    if (indexPath.row == 1 || indexPath.row == 2) {
        return indexPath
    }
    return nil        
}

myTable.allowsSelection = false

Update in Swift 3:

cell.selectionStyle = UITableViewCellSelectionStyle.none

Implement this method of UITableViewDelegate

- (BOOL)tableView:(UITableView *)tableView shouldHighlightRowAtIndexPath:(NSIndexPath *)indexPath 
{
    return NO;
}

For Swift 3:

cell.selectionStyle = .none

Swift 5

you may wanna try this too

tableView.allowsSelection = false

Swift 5

  func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    
    let cell = tableView.dequeueReusableCell(withIdentifier: "cell") as! UITableViewCell;
    cell.selectionStyle = .none
}
