TTTAttributedLabel多種顏色

Question

我有這樣的代碼

[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;}]; 

而且只有第一個字符改變顏色，但文本的其他部分並沒有改變。有任何想法嗎？

Answer 1

的問題是，我需要把.CGRef每種顏色，是我不好

Answer 2

嘗試：

[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)];
