【问题描述】：

我想根据第三部分库“TTTAttributedLabel”更改文本颜色，但这没有意义。这是我的代码：

 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;
];

【参考方案1】：

尝试使用：

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