Question

案文可在<条码>上加上使用<条码>的超文本标签。 Kit sign. 问题在于,我可以先将<代码>font应用于由此产生的构成部分。 <代码>fontWalaworking but font don t. Even underline work.

我需要老调器,而我用的是老板。即便是系统字体也不可行。

struct SecondContentView: View {
    var body: some View {
        let html = "<u>Heading</u> paragraph."

        if var nsAttributedString = try? NSAttributedString(data: Data(html.utf8), options: [.documentType: NSAttributedString.DocumentType.html], documentAttributes: nil),
           let attributedString = try? AttributedString(nsAttributedString, including: .uiKit) {

            Text(attributedString)
                .font(Font.system(size: 48))
                .fontWeight(.bold)
        } else {
            Text(html)
        }
    }
}

struct SecondContentView_Previews: PreviewProvider {
    static var previews: some View {
        SecondContentView()
    }
}

I tried other properties and only font was not working.

这在最初的主人上得到了明确表述。 (斜体):

Use this initializer to style text according to attributes found in the specified AttributedString. Attributes in the attributed string take precedence over styles added by view modifiers. For example, the attributed text in the following example appears in blue, despite the use of the foregroundColor(_:) modifier to use red throughout the enclosing VStack:
var content: AttributedString {
    var attributedString = AttributedString("Blue text")
    attributedString.foregroundColor = .blue
    return attributedString
}

var body: some View {
    VStack {
        Text(content)
        Text("Red text")
    }
    .foregroundColor(.red)
}

如果您(attributedString),你将看到它已经有了一个NSFont属性。这是产出:

Heading {
    NSKern = 0.0
    NSColor = kCGColorSpaceModelRGB 0 0 0 1 
    NSStrokeWidth = 0.0
    NSFont = <UICTFont: 0x7fb3dcd18a10> font-family: "Times New Roman"; font-weight: normal; font-style: normal; font-size: 12.00pt
    NSUnderline = NSUnderlineStyle(rawValue: 1)
    NSStrokeColor = kCGColorSpaceModelRGB 0 0 0 1 
    NSParagraphStyle = Alignment 4, LineSpacing 0, ParagraphSpacing 0, ParagraphSpacingBefore 0, HeadIndent 0, TailIndent 0, FirstLineHeadIndent 0, LineHeight 0/0, LineHeightMultiple 0, LineBreakMode 0, Tabs (
), DefaultTabInterval 36, Blocks (
), Lists (
), BaseWritingDirection 0, HyphenationFactor 0, TighteningForTruncation NO, HeaderLevel 0 LineBreakStrategy 0 PresentationIntents (
) ListIntentOrdinal 0 CodeBlockIntentLanguageHint   
}
 paragraph {
    NSColor = kCGColorSpaceModelRGB 0 0 0 1 
    NSFont = <UICTFont: 0x7fb3dcd18a10> font-family: "Times New Roman"; font-weight: normal; font-style: normal; font-size: 12.00pt
    NSStrokeColor = kCGColorSpaceModelRGB 0 0 0 1 
    NSKern = 0.0
    NSStrokeWidth = 0.0
    NSParagraphStyle = Alignment 4, LineSpacing 0, ParagraphSpacing 0, ParagraphSpacingBefore 0, HeadIndent 0, TailIndent 0, FirstLineHeadIndent 0, LineHeight 0/0, LineHeightMultiple 0, LineBreakMode 0, Tabs (
), DefaultTabInterval 36, Blocks (
), Lists (
), BaseWritingDirection 0, HyphenationFactor 0, TighteningForTruncation NO, HeaderLevel 0 LineBreakStrategy 0 PresentationIntents (
) ListIntentOrdinal 0 CodeBlockIntentLanguageHint   
}

如果你想说明一种观点,那么,仅仅删除现有的属性。

Text(attrString.transformingAttributes(AttributeScopes.UIKitAttributes.FontAttribute.self) { font in
    font.value = nil
})
.font(...)
