如何防止UITableViewCell被选择？

Question

I have selected Selection = None from the storyboard scene of that static UITableViewCell . I also added this method:

- (NSIndexPath *)tableView:(UITableView *)tableView willSelectRowAtIndexPath:(NSIndexPath *)indexPath{
    switch (indexPath.row) {
        case 1:
            return nil;
            break;
    }
}

Which doesn't particularly set well because it warns of a method not returning a value.

The cell is still selectable, one time, briefly and then no more. The cell is set up like this:

case 1:
    cell.textLabel.text = @"Search";
    break;

and the didSelectRowAtIndexPath like so:

case 1:
    NSLog(@"Unselectable Cell");
    break;

Am I missing anything else?

Answer 1

cell.userInteractionEnabled = NO;

Selection is the state right after being highlighted, if you press on a cell and it turns blue, it's being highlighted, when you release it, it has been selected.

Therefore, if you can't highlight the cell, you can't select it. With that in mind, you can do:

- (BOOL)tableView:(UITableView *)tableView shouldHighlightRowAtIndexPath:(NSIndexPath *)indexPath
{
    // I'm assuming you just want it for the row 1, right?
    if (indexPath.row == 1)
    {
        // You ain't getting selected today, son.
        return NO;
    }

    return YES;
}

What I do is I do something like so:

- (UITableViewCell *)tableView:(UITableView *)tmpTableView cellForRowAtIndexPath:   (NSIndexPath *)indexPath
{
tmpTableView.scrollEnabled = NO;
static NSString *CellIdentifier = @"MainCell";
UITableViewCell *cell = [tmpTableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (nil == cell)
{
    cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
    if(indexPath.row == 0)
    {
        cell.textLabel.textAlignment = NSTextAlignmentCenter;
        cell.userInteractionEnabled = NO;
        cell.textLabel.lineBreakMode = NSLineBreakByWordWrapping;
        cell.textLabel.numberOfLines = 4;
        cell.textLabel.textColor = [UIColor grayColor];
        cell.textLabel.font = [UIFont systemFontOfSize:16.0];
        cell.textLabel.text = [self.answerArray objectAtIndex:indexPath.row];
        [cell.textLabel setAdjustsFontSizeToFitWidth:YES];
        return cell;
    }
}
cell.textLabel.font = [UIFont systemFontOfSize:18.0];
cell.textLabel.text = [self.answerArray objectAtIndex:indexPath.row];

return cell;
}

You could go line by line, of course this would only work for tables that dont dynamically change in number of cells.

Answer 4

You can also try this

tableView.allowsSelection = NO;

another way of doing this

cell.selectionStyle = UITableViewCellSelectionStyleNone;

one more

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
[tableView deselectRowAtIndexPath:indexPath animated:YES];
}
