遇到一些服務(wù)器已經(jīng)寫好的html格式字符串,苦于webView的高度不好控制,發(fā)現(xiàn)用NSAttributedString很方便,推薦一下

oc

NSString * htmlString = @"<p><span style=\\"border: 1px solid rgb(0, 0, 0);\\"><em>好，真心好</em></span></p>";
NSAttributedString * attrStr = [[NSAttributedString alloc] initWithData:[htmlString dataUsingEncoding:NSUnicodeStringEncoding] options:@{ NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType } documentAttributes:nil error:nil];
UILabel * myLabel = [[UILabel alloc] initWithFrame:self.view.bounds];
myLabel.attributedText = attrStr;
[self.view addSubview:myLabel];

swift

let htmlString = self.bookModel.introduction
// let attrStr = NSAttributedString(data: htmlString.dataUsingEncoding(NSUnicodeStringEncoding)!, options: [NSDocumentTypeDocumentAttribute:NSHTMLTextDocumentType], documentAttributes:nil)
   let attrStr = try! NSAttributedString(
        data: htmlString.dataUsingEncoding(NSUnicodeStringEncoding)!,
        options: [NSDocumentTypeDocumentAttribute:NSHTMLTextDocumentType],
        documentAttributes: nil)
    print("\\(attrStr)")
    
    introductionView.textLabel.attributedText = attrStr
