TTTAttributedLabel多种颜色

Question

我有这样的代码

[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;}]; 

而且只有第一个字符改变颜色，但文本的其他部分并没有改变。有任何想法吗？

Answer 1

的问题是，我需要把.CGRef每种颜色，是我不好

Answer 2

尝试：

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

或：

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