UITableview: How to Disable Selection for Some Row

Question

I am displaying in a group tableview contents parsed from XML. I want to disable the click event on it (I should not be able to click it at all) The table contains two groups. I want to disable selection for the first group only but not the second group. Clicking the first row of second group navigates to my tube player view.

How can I make just specific groups or rows selectable?

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath 
{
    if(indexPath.section!=0)
    if(indexPath.row==0)    

    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:tubeUrl]];   
}

Thanks.

Answer 1

Starting in iOS 6, you can use

-tableView:shouldHighLightRowAtIndexPath:

If you return NO, it disables both the selection highlighting and the storyboard triggered segues connected to that cell.

The method is called when a touch comes down on a row. Returning NO to that message halts the selection process and does not cause the currently selected row to lose its selected look while the touch is down.

on Xcode 7 without coding you can simply do the following:

In the outline view, select Table View Cell. (The cell is nested under Table View Controller Scene > Table View Controller > Table View. You may have to disclose those objects to see the table view cell)

In the Attributes inspector, find the field labeled Selection and select None. atribute inspector With this option, the cell won’t get a visual highlight when a user taps it.

for swift 3.0 you can use below code to disable user interaction to UITableView cell

 cell.isUserInteractionEnabled = false

Answer 4

For swift 4.0 This will do the trick. It will disable the Cell in didSelectRowAtIndexPath method but keep the subviews clickable.

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

You can use the tableView:willDisplayCell method to do all the kinds of customization to a tableViewCell.

- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath
{
     [cell setSelectionStyle:UITableViewCellSelectionStyleNone];
     [cell setUserInteractionEnabled:NO];

     if (indexPath.section == 1 && indexPath.row == 0)
     {
         [cell setSelectionStyle:UITableViewCellSelectionStyleGray];
         [cell setUserInteractionEnabled:YES];
     }
} 

In this above code, the user can only select the first row in the second section of the tableView. The rest all rows can't be selected. Thanks!~

You need to do something like the following to disable cell selection within the cellForRowAtIndexPath method:

[cell setSelectionStyle:UITableViewCellSelectionStyleNone];
[cell setUserInteractionEnabled:NO];

To show the cell grayed out, put the following within the tableView:WillDisplayCell:forRowAtIndexPath method:

[cell setAlpha:0.5];

One method allows you to control the interactivity, the other allows you to control the UI appearance.
