TTTAttributedLabel多色

Question

我有这个代码

[label setText:@"ddddasdasdas" afterInheritingLabelAttributesAndConfiguringWithBlock:^ NSMutableAttributedString *(NSMutableAttributedString *mutableAttributedString) {
            [mutableAttributedString addAttribute:(NSString*)kCTForegroundColorAttributeName value:(id)[UIColor blackColor] range:NSMakeRange(0,1)];
            [mutableAttributedString addAttribute:(NSString*)kCTForegroundColorAttributeName value:(id)[UIColor redColor] range:NSMakeRange(2,3)];
            [mutableAttributedString addAttribute:(NSString*)kCTForegroundColorAttributeName value:(id)[UIColor greenColor] range:NSMakeRange(5,2)];
            return mutableAttributedString;}];

并且只有第一个字符改变颜色，但文本的其余部分不改变。有什么想法吗？

Answer 1

尝试：

[mutableAttributedString addAttribute:(NSString*)kCTForegroundColorAttributeName value:(id)[[UIColor blackColor] CGColor] range:NSMakeRange(0,1)];

或者：

[mutableAttributedString addAttribute:(NSString*)NSForegroundColorAttributeName value:(id)[[UIColor blackColor] CGColor] range:NSMakeRange(0,1)];

Answer 2

问题是我需要在每种颜色上都加上.CGRef，这是我的错
