HUD中的文本颜色为黑色。为什么以及如何将其更改为白色？

Answer 1

您应该使用NSAttributedString.Key而不是CoreText键来尝试替换以下内容：

let attribs = [ kCTFontAttributeName: UIFont.systemFont(ofSize: 66.0), kCTForegroundColorAttributeName: UIColor.white]

与此：

let attribs: [NSAttributedString.Key: Any] = [.font: UIFont.systemFont(ofSize: 66.0),
                                              .foregroundColor: UIColor.green]

Answer 2

您可以在此行更改

let attribs = [ kCTFontAttributeName: UIFont.systemFont(ofSize: 66.0), kCTForegroundColorAttributeName: UIColor.white.CGColor]

应用此属性的文本的前景色。与此属性关联的值必须是CGColor对象。默认值为黑色。 Refer here

Answer 3

尝试一下：

let attribs = [NSAttributedString.Key.font.rawValue：UIFont.systemFont（ofSize：66.0），NSAttributedString.Key.foregroundColor：UIColor.white]一样！ [String：任何]
