当调用addAttribute方法时，NSMutableAttributedString无法更改文本颜色

Question

我想根据“TTTAttributedLabel”的第三部分库更改文本颜色，但没有任何意义。这里是我的代码：

TTTAttributedLabel *priceInfoLabel.frame = [[TTTAttributedLabel alloc] initWithFrame:CGRectMake(self.view.width-12-realSize.width-priceSize.width, 15, realSize.width+priceSize.width, 18)]; 

priceInfoLabel.centerY = nameView.height/2; 
priceInfoLabel.textColor = kRealPriceColor; 
[priceInfoLabel setText:[NSString stringWithFormat:@"%@%@",realPriceText,priceText] afterInheritingLabelAttributesAndConfiguringWithBlock:^NSMutableAttributedString *(NSMutableAttributedString *mutableAttributedString) { 
    NSRange priceStringRange = [[mutableAttributedString string] rangeOfString:priceText options:NSCaseInsensitiveSearch]; 
    [mutableAttributedString addAttribute:NSFontAttributeName value:[UIFont fontWithName:nil size:12] range:priceStringRange]; 
    [mutableAttributedString addAttribute:UITextAttributeTextColor 
            value:colorWithIntegerValue(195, 195, 195) range:priceStringRange]; 
    return mutableAttributedString; 
}]; 

Answer 1

尝试使用：

[mutableAttributedString addAttribute:(NSString *)kCTForegroundColorAttributeName 
            value:colorWithIntegerValue(195, 195, 195) range:priceStringRange];
