Question

这是我的代码，用于检测文本中的URL

let detector: NSDataDetector = try NSDataDetector(types: NSTextCheckingResult.CheckingType.link.rawValue)
let matches: [NSTextCheckingResult] = detector.matches(in: message!, options: NSRegularExpression.MatchingOptions.init(rawValue: 0), range: NSMakeRange(0, (message?.count)!))
var url: URL?
for item in matches {
    let match = item as NSTextCheckingResult
    url = match.url
    print(url!)
    break
}

但是，此代码使www.example.com成为http://example.com

我想要的是像https://example.com一样以HTTPS形式获取此URL

我该如何实现？

当没有找到没有方案的URL时，没有API告诉NSDataDetector默认为https URL方案。

一种选择是自己更新生成的URL：

let message = "www.example.com"
let detector = try NSDataDetector(types: NSTextCheckingResult.CheckingType.link.rawValue)
let matches = detector.matches(in: message, range: NSRange(location: 0, length: message.utf16.count))
var url: URL?
for match in matches {
    if match.resultType == .link {
        url = match.url
        if url?.scheme == "http" {
            if var urlComps = URLComponents(url: url!, resolvingAgainstBaseURL: false) {
                urlComps.scheme = "https"
                url = urlComps.url
            }
        }
        print(url)
        break
    }
}

以HTTPS格式检测文本中的url
