我在iOS中开发了一个应用程序,我的要求是将HTML字符串转换为NSAttributed字符串和NSAttributed字符串转换回HTML。 我能够实现的第一部分。但是NSAttributed String to HTML没有发生。它返回HTML中的字符串,但不是按照需要。 请参考下面的代码和输出:上述代码工作所需NSAttribute string to HTML
HTML到NSAttributed字符串
NSString *htmlString = @"<div>Test, </div><div> </div><div>Test Test Test</div><div>Test Test Test </div><div> </div><div>Format text:</div><ul style="margin:0;padding-left:36pt;"><li><b>bold text</b></li><li><i>italic text</i></li><li><font color="red"><i>red text</i></font></li></ul><div> </div><div><i>The meeting body</i><i> </i><i>attachments</i></div>";
NSAttributedString *normal = [[NSAttributedString alloc] initWithData:[htmlString dataUsingEncoding:NSUTF8StringEncoding] options:@{NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType, NSCharacterEncodingDocumentAttribute: [NSNumber numberWithInt:NSUTF8StringEncoding]} documentAttributes:nil error:nil];
textView = [[UITextView alloc]initWithFrame:CGRectMake(10, 20, 500, 500)];
textView.attributedText = normal;
[self.view addSubview:textView];
....
NSAttributed字符串为HTML
NSAttributedString *s = textView.attributedText;
NSDictionary *documentAttributes = [NSDictionary dictionaryWithObjectsAndKeys:NSHTMLTextDocumentType, NSDocumentTypeDocumentAttribute, nil];
NSData *htmlData = [s dataFromRange:NSMakeRange(0, s.length) documentAttributes:documentAttributes error:NULL];
NSString *htmlString = [[NSString alloc] initWithData:htmlData encoding:NSUTF8StringEncoding];
此代码不起作用..我不明白d输出.. 输出我得到的是:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<meta http-equiv="Content-Style-Type" content="text/css">
<title></title>
<meta name="Generator" content="Cocoa HTML Writer">
<style type="text/css">
p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px 'Times New Roman'; color: #000000; -webkit-text-stroke: #000000}
span.s1 {font-family: 'Times New Roman'; font-weight: normal; font-style: normal; font-size: 12.00pt; font-kerning: none}
</style>
</head>
<body>

<p class="p1"><span class="s1"> </span></p>

webEditor在你的最后一行代码中是什么? –
这是一个WebView对象。 –
