如何在UILabel Swift IOS中添加Stroke

Question

在向UILabel App Crashes添加Stroke时

---

由于发现零而崩溃

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)
