Question

如何检测字符串是否包含字符串（单词）数组的任何成员？

这是数组：

let str:String = "house near the beach"
 let wordGroups:[String] = ["beach","waterfront","with a water view","near ocean","close to water"]

以下内容未编译

let match:Bool = wordGroups.contains(where: str.contains)

Answer 1

除了@Sh_Khan的答案外，如果您想匹配组中的某个单词：

let str:String = "house near the beach"
let wordGroups:[String] = ["beach","waterfront","with a water view","near ocean","close to water"]
let worlds = wordGroups.flatMap { $0.components(separatedBy: " ")}
let match = worlds.filter { str.range(of:$0) != nil }.count != 0

Answer 2

您可以尝试

let str = Set("house near the beach")
let match = wordGroups.filter { str.contains($0) }.count != 0

Answer 3

我正在使用 String 扩展名：

extension String {
    func contains(_ strings: [String]) -> Bool {
        strings.contains { contains($0) }
    }
}

用例：

let str = "house near the beach"
let wordGroups = ["beach","waterfront", "with a water view", "near ocean", "close to water"]
let haveWord = str.contains(wordGroups)
