UITableView checkmark & sections

I am mak开发者_如何学JAVAing a UITableView that allows cells to be selected (like the languanges `TableView\, but once one) but the checkmark accessory isn't working.

if (tableView == self.numberTableView) {
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
    }
    cell.text = [arryNumber objectAtIndex:indexPath.row];
    if ([cell.textLabel.text isEqualToString:@"0"])
    {
        if (inumberfont == 0) {
            cell.accessoryType = UITableViewCellAccessoryCheckmark;
            }else {
            cell.accessoryType = UITableViewCellAccessoryNone;
        }
    }
    if ([cell.textLabel.text isEqualToString:@"1"])
    {
        if (inumberfont == 1) {
            cell.accessoryType = UITableViewCellAccessoryCheckmark;
            }else {
            cell.accessoryType = UITableViewCellAccessoryNone;
        }
    }
    if ([cell.textLabel.text isEqualToString:@"2"])
    {
        if (inumberfont == 2) {
            cell.accessoryType = UITableViewCellAccessoryCheckmark;
            }else {
            cell.accessoryType = UITableViewCellAccessoryNone;
        }
    }
    if ([cell.textLabel.text isEqualToString:@"3"])
    {
        if (inumberfont == 3) {
            cell.accessoryType = UITableViewCellAccessoryCheckmark;
            }else {
            cell.accessoryType = UITableViewCellAccessoryNone;
        }
    }
    if ([cell.textLabel.text isEqualToString:@"4"])
    {
        if (inumberfont == 4) {
            cell.accessoryType = UITableViewCellAccessoryCheckmark;
            }else {
            cell.accessoryType = UITableViewCellAccessoryNone;
        }
    }
}

Can someone help?

I rewrote your code.

if (tableView == self.numberTableView) {
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
    }
    cell.text = [NSString stringWithFormat:@"%i", indexPath.row];
    if (inumberfont == indexPath.row) {
        cell.accessoryType = UITableViewCellAccessoryCheckmark;
    } else {
        cell.accessoryType = UITableViewCellAccessoryNone;
    }
}

The above code does the exact same thing as your code, but well, your code wasn't working. In the following code I've fixed the errors I spotted. I also added some missing code. If you had it before, but didn't include it, that's fine; I just wanted to make sure that it wasn't missing.

if (tableView == self.numberTableView) {
    static NSString *CellIdentifier = @"NumberCell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
    }
    cell.textLabel.text = [NSString stringWithFormat:@"%i", indexPath.row];
    if (inumberfont == indexPath.row) {
        cell.accessoryType = UITableViewCellAccessoryCheckmark;
    } else {
        cell.accessoryType = UITableViewCellAccessoryNone;
    }
    return cell;
}

I'm not sure what you mean by "the checkmark accessory isn't work", but try improving your code with my suggestions and if it still doesn't work, drop a comment and I'll see what I can do to help you further.

EDIT: Found out what the problem was. Try the following:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    inumberfont = indexPath.row;
    [tableView reloadData];
}

What is the line:

cell.text = [arryNumber objectAtIndex:indexPath.row];

What is cell.text? Don't you mean cell.textLabel.text

By the way I think you could probably condense your code by doing:

if ([cell.textLabel.text intValue] == inumberfont) {
    cell.accessoryType = UITableViewCellAccessoryCheckmark;
} else {
    cell.accessoryType = UITableViewCellAccessoryNone;
}

You wouldn't need all 8 if statements just that one.
