UILabel text color changes when text is changed

The UILabel is created in Interface builder. It is part of a UITableViewCell. Its color is set to red in Interface Builder.

I create the cells here:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"notationcell";
    NotationCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];

    // Configure the cell...
    cell.notation = [self.notations objectAtIndex:indexPath.row];

    UIColor *before = cell.symbolLabel.textColor;
    cell.symbolLabel.text = @"new text";
    UIColor *after = cell.symbolLabel.textColor;

    return cell;
}

Before is red, as intended. But after changing the text the after color becomes UIDeviceWhiteColorSpace 0 1, and the text becomes black. I am using AutoLayout.

Why does changing the text imply the change of its color?

If you want the text color to be permanently red try setting the Label's text color in the delegate method itself rather than from XIB:

  - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"notationcell";
    NotationCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];

    // Configure the cell...
    cell.notation = [self.notations objectAtIndex:indexPath.row];

    cell.symbolLabel.text = @"new text";
    cell.symbolLabel.textColor = [UIColor RedColor];

    return cell;
}

Found a solution. I created a category:

@implementation UILabel (KeepAttributes)

- (void)setTextWithKeepingAttributes:(NSString *)text{

    NSDictionary *attributes = [(NSAttributedString *)self.attributedText attributesAtIndex:0 effectiveRange:NULL];
    self.attributedText = [[NSAttributedString alloc] initWithString:text attributes:attributes];

}

@end

Then used this method to change the text.
