swift - 将子字符串与 Swift 中的另一个子字符串匹配

Question

我正在研究 Swift 4。

需求:我有一个字符串:

var inputString = "Today is very bright day"

我有一个包含字符串键值对的文件。

{
    "Birthday": ["brand day", "burn day", "bright day", "brick daya"],
    "Temporary": ["tempora", "temporar", "tempura"]
}

所需的数学运算:在应用程序中，如果 inputString 是 "Today is very bright day"，我需要检查此字符串是否包含键值对文件中的任何值，并且用键替换出现的地方。

例如:在上面的例子中:inputString = "Today is very bright day"将其与文件匹配。将 bight day 替换为 birthday 以便 inout 字符串变为inputString = "今天是生日".

有什么办法吗？键值文件可能很大。

Answer 1

您可以使用暴力解决方案，它将是 2 个 for 循环，我正在努力增强它

  var inputString = "Today is very bright day"

        let file  = ["Birthday":["brand day", "burn day", "bright day", "brick daya"],"Temporary": ["tempora", "temporar", "tempura"]]

        file.forEach { (key,value) in
            value.forEach({ (item) in
               inputString =  inputString.replacingOccurrences(of: item, with: key)
            })
        }

        print(inputString)
