Question

我正在开发一个测验应用程序，我正在屏幕上显示标签和几个按钮。我有一个数组，其中包含标签和按钮的问题和答案。向用户显示一个颜色的单词，用户应该单击与该颜色的单词对应的按钮。但是每次在问题内部更改时，我都找不到改变标签颜色的方法。阵列。

这是我的编码：

Colors = [Color (Color: (UIColor.red("Red")), Answers: ["Red","Blue","Yellow","Green"], Answer: 0 ),
                  Color(Color: "Blue", Answers: ["Red","Blue","Yellow","Green"], Answer: 1 ),
                  Color(Color: "Green", Answers: ["Red","Blue","Yellow","Green"], Answer: 3 ),
                  Color(Color: "Yellow", Answers: ["Red","Blue","Yellow","Green"], Answer: 2 )]

UIColor.red（＆＃34; Red＆＃34;）根据快速语言错误

Answer 1

最简单的解决方案是将颜色属性的类型从UIColor更改为String，然后你就可以了。

Colors = [Color(Color: UIColor.red, Answers: ["Red","Blue","Yellow","Green"], Answer: 0 ),
              Color(Color: UIColor.blue, Answers: ["Red","Blue","Yellow","Green"], Answer: 1 ),
              Color(Color: UIColor.green, Answers: ["Red","Blue","Yellow","Green"], Answer: 3 ),
              Color(Color: UIColor.yellow, Answers: ["Red","Blue","Yellow","Green"], Answer: 2 )]
