How to setHighlightedTextColor @NSAttributedString

Question

I have a custom UITableViewCell that uses NSAttributedString. I want it to change color when a cell is selected. How can I make NSAttributedString have the same behavior as a UILabel with a selected TextColor?

I tried changing the color in the setSelected and setHighlighted functions from the cell, but it seems like they are called until late (on touchUpInside instead of touchDown)

Thanks in advance!

UILabel subclass solution

@implementation CustomLabelHighlighted
{
    NSAttributedString *savedAttributedString;
}

-(void)setHighlighted:(BOOL)highlighted
{
    [super setHighlighted:highlighted];

    if (!highlighted) 
    {
       [super setAttributedText:savedAttributedString];
       return;
    }

    NSMutableAttributedString *highAttributedString = [savedAttributedString mutableCopy];
    NSRange range = NSMakeRange(0, highAttributedString.string.length);
    [highAttributedString addAttribute:NSForegroundColorAttributeName value:self.highlightedTextColor range:range];
    [super setAttributedText:highAttributedString];
}

- (void)setAttributedText:(NSAttributedString *)attributedText
{
    [super setAttributedText:attributedText];
    savedAttributedString = attributedText;
}

@end

It is usually quite easy to detect selection / selection and change colors depending on this. Important methods are:

-(void)setHighlighted:animated:
-(void)setSelected:animated:

, animated:, .
