我将我的代码从Swift 3转换为Swift 4但是出现了这个错误：
输入＆＃39; NSAttributedStringKey＆＃39;没有会员＆前台色彩分布式串口＆＃39;
我的代码是：
let labelText = NSMutableAttributedString(string: (self.productDetailsInfo?.productAttributes?[indexPath.row].Name as String?)!)
labelText.append(NSAttributedString(string:"*"))
let selectedRange = NSMakeRange(labelText.length - 1, 1);
labelText.addAttribute(NSAttributedStringKey.foregroundColorNSAttributedStringKey.foregroundColor, value: UIColor.red, range: selectedRange)
labelText.addAttribute(NSAttributedStringKey.baselineOffset, value: 2, range: selectedRange)
答案 0 :(得分：1)
foregroundColorNSAttributedStringKey
直接在NSAttributedString.Key
将NSAttributedStringKey.foregroundColorNSAttributedStringKey.foregroundColor替换为代码中的NSAttributedStringKey.foregroundColor。
试试这个：
let labelText = NSMutableAttributedString(string: (self.productDetailsInfo?.productAttributes?[indexPath.row].Name as String?)!)
labelText.append(NSAttributedString(string:"*"))
let selectedRange = NSMakeRange(labelText.length - 1, 1);
// Remove foregroundColorNSAttributedStringKey
// Swift 4.1
labelText.addAttribute(NSAttributedStringKey.foregroundColor, value: UIColor.red, range: selectedRange)
labelText.addAttribute(NSAttributedStringKey.baselineOffset, value: 2, range: selectedRange)
// Swift 4.2
labelText.addAttribute(NSAttributedString.Key.foregroundColor, value: UIColor.red, range: selectedRange)
labelText.addAttribute(NSAttributedString.Key.baselineOffset, value: 2, range: selectedRange)
答案 1 :(得分：0)
替换行

<!-- Execute "mvn clean package -Pbuild-jar" to build a jar file out of
this project! How to use the Flink Quickstart pom: a) Adding new dependencies:
You can add dependencies to the list below. Please check if the maven-shade-plugin
below is filtering out your dependency and remove the exclude from there.
b) Build a jar for running on the cluster: There are two options for creating
a jar from this project b.1) "mvn clean package" -> this will create a fat
jar which contains all dependencies necessary for running the jar created
by this pom in a cluster. The "maven-shade-plugin" excludes everything that
is provided on a running Flink cluster. b.2) "mvn clean package -Pbuild-jar"
-> This will also create a fat-jar, but with much nicer dependency exclusion
handling. This approach is preferred and leads to much cleaner jar files. -->

此外，您可以使用 labelText.addAttribute(NSAttributedStringKey.foregroundColor, value: UIColor.red, range: selectedRange)
方法一次为范围
addAttributes答案 2 :(得分：0)
在Swift 4中设置前景色属性：
[NSForegroundColorAttributeName: UIColor.white]
