Superscript屬性不再適用於iOS 10.3

Question

我最近注意到，作爲NSAttributedString的超文本文本不再適用於iOS 10.3。

有沒有其他人注意到了這一點？此代碼用於工作，使我的註冊標誌標：

func setSuperScript(forSuperScriptString superScriptString:String, withFont font:String, atSize size:CGFloat){ 

    if self.text != nil { 

     let mutableAttString:NSMutableAttributedString = NSMutableAttributedString(string:self.text!) 

     for (i,c) in self.text!.characters.enumerated() { 

      if c == Character(superScriptString) { 

       let range = NSRange(location:i,length:1) 

       // for each occurence of the character to superscript 
       mutableAttString.addAttribute(NSFontAttributeName, value: UIFont(name: font, size: size)!, range: range) 
       mutableAttString.addAttribute(kCTSuperscriptAttributeName as String, value:1, range: range) 
      } 
     } 

     self.attributedText = mutableAttString 
    } 
} 

該行上運行iOS的設備10.2作品mutableAttString.addAttribute(kCTSuperscriptAttributeName as String, value:1, range: range)但確實在iOS的最新版本。

我有這樣的代碼來右上角的貨幣標籤美分，它工作得很好，因爲iOS的8至10.3.1：

func formatLabelToCurrency(label: UILabel)-> UILabel { 
    var decimalSeparator: String = "." 
    let font:UIFont? = UIFont(name: "Helvetica", size:20) 
    let fontSuper:UIFont? = UIFont(name: "Helvetica", size:10) 
    let attString:NSMutableAttributedString = NSMutableAttributedString(string: label.text!, attributes: [NSFontAttributeName:font!]) 
    attString.setAttributes([NSFontAttributeName:fontSuper!,NSBaselineOffsetAttributeName:10], range: NSRange(location:(label.text?.index(of: decimalSeparator))!,length:3)) 
    label.attributedText = attString; 
    return label 
}
