ios - NSAttributedString 文本打印出灰色而不是黑色？

Question

我传入一串文本并将字符串中的名称设为粗体和黑色，其余部分只是常规黑色。但是，它不起作用并且名称显示为灰色？

cell.acceptedLabel.attributedText = attributedFunc(stringinput: "\(currentUser.notifications[indexPath.row - 1].usersName ?? "Someone") accepted your buddy request.", indexPathRow: indexPath.row - 1)

func attributedFunc(stringinput: String, indexPathRow: Int) -> NSMutableAttributedString {

        let amountText = NSMutableAttributedString.init(string: stringinput)
        print(stringinput)
        if currentUser.notifications[indexPathRow].type == "buddyRequestAccepted" {

            let usersName = currentUser.notifications[indexPathRow].usersName
            print(usersName)
            let usersNameDigits = usersName?.count
            amountText.setAttributes([NSAttributedStringKey.font: UIFont.systemFont(ofSize: 15),
                                      NSAttributedStringKey.foregroundColor: UIColor.black, NSAttributedStringKey.strokeWidth: UIFont.Weight.semibold],
                                     range: NSMakeRange(0, usersNameDigits!))

            amountText.setAttributes([NSAttributedStringKey.font: UIFont.systemFont(ofSize: 15), NSAttributedStringKey.foregroundColor: UIColor.black, NSAttributedStringKey.strokeWidth: UIFont.Weight.regular], range: NSMakeRange(usersNameDigits! + 1, 12))

            // if you want, you can add more attributes for different ranges calling .setAttributes many times
            print(amountText)
            return amountText

        } else if currentUser.notifications[indexPathRow].type == "memberRequestAccepted" {
            return amountText
        }
        return amountText
    }

这里我控制台打印出字符串、名称和总的 NSAttributedString:

Austin accepted your buddy request.

Optional("Austin")

Austin{
    NSColor = "UIExtendedGrayColorSpace 0 1";
    NSFont = "<UICTFont: 0x7fb062f3d2c0> font-family: \".SFUIText\"; font-weight: normal; font-style: normal; font-size: 15.00pt";
    NSStrokeWidth = "0.300000011920929";
} {
}accepted you{
    NSColor = "UIExtendedGrayColorSpace 0 1";
    NSFont = "<UICTFont: 0x7fb062f3d2c0> font-family: \".SFUIText\"; font-weight: normal; font-style: normal; font-size: 15.00pt";
    NSStrokeWidth = 0;
}r buddy request.{
}

这是因为您将权重设置为 strokeWidth NSAttributedStringKey.strokeWidth: UIFont.Weight.semibold。您可以使用以下可能对您有所帮助的代码。

amountText.setAttributes([NSAttributedString.Key.font: UIFont.systemFont(ofSize: 15, weight: .semibold),
                              NSAttributedString.Key.foregroundColor: UIColor.black],
                             range: NSMakeRange(0, usersNameDigits))
