私はJSONからいくつかの単純なHTMLの周りを変更するためにDTCoreTextを取得しようとしていました。私は単純な "Smoke Text"を実装しようとしていましたが、この例ではスイッチを動作させるのに問題があります。私は実際にこの時点でDTCoreTextを使用しているのかどうかは分かりません。DTCoreText Swift 3の問題
func updatethePage(){
if let items = self.swiftyJsonVar2["daily"]["leadmessage"].string {
data = items.data(using: .utf8)
attrString = NSAttributedString(htmlData: data,options:nil, documentAttributes:nil)
print(attrString)
self.leadStory.attributedText = attrString!
}
}
私は今、それが実行しているが、それは投げているエラーは、私だけではなく、通常のlablelのDTCoreTextViewContentにこれを配置しなければならなかった
Optional(This is the lead message

「問題」とは何ですか?コンパイラエラー?ランタイムエラー?間違った結果? –
Martin私は答えを更新しました。 DTCoreTextは少し謎めいていて、たくさんの古いコードが敷かれています。その使い方を取ろうとしています。 – BostonMacOSX
