     if balance.contains(".") { 
      myMutableString.addAttributes([NSFontAttributeName: UIFont.systemFont(ofSize: 22)], range: NSRange(location: balance.length - 2, length: 2)) 
     } 

Answer 1

我相信这是新旧金山字体的问题。

一种解决方法是使用黑体

let balance = "₦ 450.00" 
let myMutableString = NSMutableAttributedString(string: balance, attributes: [NSFontAttributeName: UIFont(name: "Helvetica Neue", size: 48.0)!]) 
if balance.containsString(".") { 
    myMutableString.addAttributes([NSFontAttributeName: UIFont(name: "Helvetica Neue", size: 22.0)!], range: NSRange(location: balance.characters.count - 2, length: 2)) 
} 

注：雨燕3.0

：不幸的是，我没有，我仍然在使用雨燕2.2

编辑迁移到斯威夫特3

let balance = "₦ 450.00" let myMutableString = NSMutableAttributedString(string: balance, attributes: [NSFontAttributeName: UIFont(name: "Helvetica Neue", size: 48.0)!]) if balance.contains("."){ myMutableString.addAttributes([NSFontAttributeName: UIFont(name: "Helvetica Neue", size: 22.0)!], range: NSRange(location: balance.characters.count - 2, length: 2)) }
