我完成遷移我的應用程序swift3但是這部分持續高產導致的問題。- [_ SwiftValue unsignedIntegerValue]：無法識別的選擇發送到實例0x608000243d50（LLDB）

override func viewWillAppear(_ animated: Bool) 
{ 
    super.viewWillAppear(animated) 
    self.navigationController?.setNavigationBarHidden(false, animated: animated) 
    self.navigationItem.title = artworkTitle 


    let title = "<center><span style=\"font-size: 17px;font-weight:lighter;font-family:Avenir-Book;\">" + artworkCaption + "</span></center>" 
    artworkImageView.image = UIImage(named: artworkImagePath) 

    artworkCaptionView.attributedText = title.html2AttStr 
}

更換NSCharacterEncodingDocumentAttribute: String.Encoding.utf8如果你的代碼與我們分享，請不要發佈它作爲圖像。你可以把它添加到您的帖子，[格式設置爲代碼（http://stackoverflow.com/editing-help#code）。 – FelixSFD

和發佈所有相關的代碼，這是很難說這是怎麼回事就沒有更多的上下文 – Miknash

郵政'html2AttStr'擴展的代碼。似乎在那裏。 –

我記得reading on Apple's Swift blog，如果你無法識別的選擇錯誤，這意味着斯威夫特結構的自動包裝是導致的問題。最有可能的是包裝String.Encoding，而不是將其轉換爲NSNumber（背後是什麼在NSMutableAttributedString Objective-C代碼期待）的。

嘗試用NSCharacterEncodingDocumentAttribute: String.Encoding.utf8.rawValue
