Question

'的参数列表调用初始值设定项我遵循本示例来解码HTML值。 TO decode a json parsed value: answered by akashivskyy

我有这个代码，我收到以下错误：

let encodedString = "The Weeknd ‘King Of The Fall’" 

let encodedData = encodedString.dataUsingEncoding(NSUTF8StringEncoding)! 

let attributedOptions : [String: AnyObject] = [ 
    NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType, 
    NSCharacterEncodingDocumentAttribute: NSUTF8StringEncoding 
] 

let attributedString = NSAttributedString(data: encodedData, options: attributedOptions, documentAttributes: nil, error: nil)! 

let decodedString = attributedString.string 

错误：

Cannot invoke initializer for type 'NSAttributedString' with an argument list of type '(data: NSData, options: [String : AnyObject], documentAttributes: _, error: _)'

任何帮助表示赞赏建议AY答案。

取下NSAttributedString初始化的error选项，并添加try代替：

let attributedString = try? NSAttributedString(data: encodedData, options: attributedOptions, documentAttributes: nil)
