DTCoreText 有 Swift 3 个问题

Question

我试图让 DTCoreText 从 JSON 改变一些简单的 HTML。我试图实现他们在示例中给出的简单 "Smoke Text"，但我在让开关正常工作时遇到了问题。 swift 3.

有没有人用过

我不确定此时我是否真的在使用 DTCoreText。

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!
    }


}

我现在有了它运行但它抛出的错误是

Optional(This is the lead message
And naother line
{
    CTForegroundColor = "<CGColor 0x600000085c80> [<CGColorSpace 0x6000000348e0> (kCGColorSpaceICCBased; kCGColorSpaceModelMonochrome; Generic Gray Gamma 2.2 Profile; extended range)] ( 0 1 )";

})

我不得不将其放入 DTCoreText ViewContent 而不是普通标签。
