问题描述
我想在 UITextView 中显示带有< blockquote> 标签的HTML文本。
HTML示例：
< div>
< blockquote class =uncited>
< div>
< cite> Nick：< / cite>
< blockquote class =uncited>
< div>
< cite> Tom：< / cite>审查< br>
Hello
< / div>
< / blockquote>
< p>世界< / p>
< / div>
< / blockquote>
< p>文字< / p>
< / div>
我使用以下代码在单元格中显示HTML文本：
UITextView * textView =（UITextView *）[cell viewWithTag：100];
NSAttributedString * attributedString = [[NSAttributedString alloc] initWithData：[thisComment.htmlText dataUsingEncoding：NSUnicodeStringEncoding] options：@ {NSDocumentTypeDocumentAttribute：NSHTMLTextDocumentType} documentAttributes：nil error：nil];
textView.attributedText = attributedString;
但是在 UITextView 中它看起来像纯文本。我想得到它：
I want to display HTML text with <blockquote> tags in the UITextView.
example of HTML:
<div>
<blockquote class="uncited">
<div>
<cite>Nick:</cite>
<blockquote class="uncited">
<div>
<cite>Tom:</cite>censored<br>
Hello
</div>
</blockquote>
<p>World</p>
</div>
</blockquote>
<p>Text</p>
</div>
I use the following code to display HTML text in the cell:
UITextView *textView = (UITextView*)[cell viewWithTag:100];
NSAttributedString *attributedString = [[NSAttributedString alloc] initWithData:[thisComment.htmlText dataUsingEncoding:NSUnicodeStringEncoding] options:@{ NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType } documentAttributes:nil error:nil];
textView.attributedText = attributedString;
But in the UITextView it's looks like plain text. I want to get it: sample
How can i do this? What kind of libraries should i use? i think about HTML -> Markdown -> NSAttributedString -> TextView
解决方案
Apple's HTML to AttributedText parser is excellent with CSS so you can actually write it like you'd do for a raw web client.
let parsedCommentHTML = html.replacingOccurrences(of: "<blockquote>\n", with: "<blockquote>\n<k style=\"color:#ccc; font-size: 2em; font-family: 'Copperplate'\">"</k>")
let blockQuoteCSS = "\nblockquote > p {color:#808080; display: inline;} \n blockquote { background: #f9f9f9;}"
let pCSS = "p {margin-bottom: 0px;}"
let cssStyle = "\(blockQuoteCSS)\n\(pCSS)\n"
return try NSAttributedString(data: ("<html><head><style>\(cssStyle)</style></head><span style=\"font-family: HelveticaNeue-Thin; font-size: 17\">\(CONTENT)</span></html>").data(using: String.Encoding.unicode)!, options: [NSDocumentTypeDocumentAttribute : NSHTMLTextDocumentType], documentAttributes: nil)
This produces a nice (in my opinion) looking quote:
