导读：以下代码与旧swift完美配合.这是String的扩展 func stringByConvertingHTML() - String { let newString = replacingOccurrences(of: "n",with: "br") if let encodedData = newString.data(using: String.Encoding.utf8) { let attributedOptions : [Strin

以下代码与旧swift完美配合.这是String的扩展

func stringByConvertingHTML() -> String {
    let newString = replacingOccurrences(of: "n",with: "<br>")
    if let encodedData = newString.data(using: String.Encoding.utf8) {
        let attributedOptions : [String: AnyObject] = [
            NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType as AnyObject,NSCharacterEncodingDocumentAttribute: String.Encoding.utf8 as AnyObject
        ]
        do {
            let attributedString = try NSAttributedString(data: encodedData,options: attributedOptions,documentAttributes: nil) //Crash here
            return attributedString.string
        } catch {
            return self
        }
    }
    return self
}

但是在迅速的3中,它崩溃了

*** Terminating app due to uncaught exception
‘NSInvalidArgumentException’,reason: ‘-[_SwiftValue
unsignedIntegerValue]: unrecognized selector sent to instance
0x6080002565f0’

有人请建议我需要做什么？

解决方法

我遇到了同样的问题：

let attributedOptions : [String: AnyObject] = [
            NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType as AnyObject,NSCharacterEncodingDocumentAttribute: String.Encoding.utf8 as AnyObject
        ]

这里的String.Encoding.utf8类型检查失败.使用NSNumber(值：String.Encoding.utf8.rawValue)
