从 Sqlite3 加载 UIWebView

Question

我有一个从 sqlite3 填充的 NSString 变量“body”。 字符串用 '\n' 和 '\t' 格式化，这样在 NSLog 中打印时看起来像

我正在尝试将此字符串加载到 UIWebView 中，并且仍然保留我浏览并发现的所有格式。

NSString *body contains the above string with all the formatting.

NSData* data=[body dataUsingEncoding:NSUTF8StringEncoding];

 if (data) {  
[webView loadData:data MIMEType:@"text/html" textEncodingName:@"UTF-8" baseURL:nil];  
       }

但我在 UIWebView 中看到格式没有保留，它变成了这样：

谁能来救我？

也许您应该在字符串周围添加 p 标签并在每行末尾添加 br：

<p>
gagan<br/>

在 UTF8 编码之前你应该使用类似的东西：

body = [NSString stringWithFormat:@"<p>%@</p>", body];
body = [body stringByReplacingOccurrencesOfString:@"\n" withString:@"<br/>\n"];
