是的，关键是将负的值应用于NSStrokeWidthAttributeName，如果此值为正，您将只看到笔触，而不是填充。
Objective-C：
self.label.attributedText=[[NSAttributedString alloc]
initWithString:@"string to both stroke and fill"
attributes:@{
NSStrokeWidthAttributeName: @-3.0,
NSStrokeColorAttributeName:[UIColor yellowColor],
NSForegroundColorAttributeName:[UIColor redColor]
}

Swift 4版本：
let attributes: [NSAttributedStringKey : Any] = [.strokeWidth: -3.0,
.strokeColor: UIColor.yellow,
.foregroundColor: UIColor.red]
label.attributedText = NSAttributedString(string: text, attributes: attributes)Swift 5.1版本：
let attributes: [NSAttributedString.Key : Any] = [.strokeWidth: -3.0,
.strokeColor: UIColor.yellow,
.foregroundColor: UIColor.red]
label.attributedText = NSAttributedString(string: text, attributes: attributes)Stack Overflow用户

Swift版本：
let attributes = [NSStrokeWidthAttributeName: -3.0,
NSStrokeColorAttributeName: UIColor.yellowColor(),
NSForegroundColorAttributeName: UIColor.redColor()];
label.attributedText = NSAttributedString(string: "string to both stroke and fill", attributes: attributes)Swift 3版本：
let attributes = [NSStrokeWidthAttributeName: -3.0,
NSStrokeColorAttributeName: UIColor.yellow,
NSForegroundColorAttributeName: UIColor.red] as [String : Any]
label.attributedText = NSAttributedString(string: "string to both stroke and fill", attributes: attributes)Stack Overflow用户

现在，swift apple的最新版本删除了字符串: Any，用于属性键值声明，用作NSAttributedStringKey : Any
let strokeTextAttributes = [
NSAttributedStringKey.strokeColor : UIColor.green,
NSAttributedStringKey.foregroundColor : UIColor.lightGray,
NSAttributedStringKey.strokeWidth : -4.0,
NSAttributedStringKey.font : UIFont.boldSystemFont(ofSize: 52)
] as [NSAttributedStringKey : Any]
hello_cell_lb.attributedText = NSAttributedString(string: "\(hello_array[indexPath.row])", attributes: strokeTextAttributes)谢谢
