Can't change button title style in iOS: attributedString

I want to update the title of an iOS UIButton named cardButton, with the RED word mat.

Here is my code:

NSMutableAttributedString *mat = [card.contents mutableCopy];
NSInteger _stringLength=[mat length];
UIColor *color;
color = [UIColor redColor];
[mat addAttribute:NSForegroundColorAttributeName value:color range:NSMakeRange(0, _stringLength)];
[cardButton setAttributedTitle: mat forState:UIControlStateNormal];

NSLog returns the right word for the word mat. I have the following error. I know there is a problem with memory management, but I don't know what.

-[__NSCFString addAttribute:value:range:]: unrecognized selector sent to instance 0x7177370

Thanks!

Replace 

NSMutableAttributedString *mat = [card.contents mutableCopy];

with this :

 NSMutableAttributedString *mat = [[NSMutableAttributedString alloc] initWithString:[card.contents mutableCopy]];
