swift - 在 xcode8 中将上标放入标签中

Question

我正在创建一个数学应用程序，并且想要一个上标 2。我一直无法找到不是基线偏移的 xcode 8 解决方案

finalFunc.text = "Converted: \(printA)(x+\(printB))^2+\(printC)" 

Answer 1

已更新为 Swift4

let font:UIFont? = UIFont(name: "Helvetica", size:20)
let fontSuper:UIFont? = UIFont(name: "Helvetica", size:10)
let attString:NSMutableAttributedString = NSMutableAttributedString(string: "xcode8", attributes: [NSAttributedString.Key.font:font!])
attString.setAttributes([NSAttributedString.Key.font:fontSuper!,NSAttributedString.Key.baselineOffset:10], range: NSRange(location:5,length:1))

labelname.attributedText = attString
