ios - DTCoreText 与 Swift 3 问题

Question

我试图让 DTCoreText 改变一些来自 JSON 的简单 HTML。我试图实现他们在示例中给出的简单“烟雾文本”，但我在让开关正常工作时遇到了问题。有没有人在swift 3中用过。

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!
    }


}

我现在让它运行了，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 )";

})

Answer 1

我必须将其放入 DTCoreText ViewContent 而不是普通标签。
