推荐答案

这里是 Swift 4.2 中的完整示例

Here is a complete example in Swift 4.2

func matchesForRegexInText(regex: String!, text: String!) -> [String] {

do {

    let regex = try NSRegularExpression(pattern: regex, options: [])
    let nsString = text as NSString

    let results = regex.matches(in: text,
                                        options: [], range: NSMakeRange(0, nsString.length))
    return results.map { nsString.substring(with: $0.range)}

} catch let error as NSError {

    print("invalid regex: \(error.localizedDescription)")

    return []
}}

和用法:

let regex = "\\((.*?)\\)"
mmatchesForRegexInText(regex: regex, text: " exmaple (android) of (qwe123) text (heart) between parentheses")
