Objective-C：如何替换HTML实体？ [英] Objective-C: How to replace HTML entities?

问题描述

我从互联网获取文本，它包含html实体（即& oacute; =ó）。我想将这个文本显示到一个自定义的iPhone单元格中。

我试图在我的自定义单元格中使用UIWebView，但我更喜欢使用多行UILabel。问题是我找不到任何替换这些HTML实体的方法。 解决方案

查看我的 HTML的NSString类别。以下是可用的方法：

   - （NSString *）stringByConvertingHTMLToPlainText; 
  - （NSString *）stringByDecodingHTMLEntities; 
  - （NSString *）stringByEncodingHTMLEntities; 
  - （NSString *）stringWithNewLinesAsBRs; 
  - （NSString *）stringByRemovingNewLinesAndWhitespace; 
  

I'm getting text from Internet and it contains html entities (i.e. ó = ó). I want to show this text into a custom iPhone cell.

I've tried to use a UIWebView into my custom cell but I prefer to use a multiline UILabel. The problem is I can't find any way of replacing these HTML entities.

解决方案

Check out my NSString category for HTML. Here are the methods available:

- (NSString *)stringByConvertingHTMLToPlainText;
- (NSString *)stringByDecodingHTMLEntities;
- (NSString *)stringByEncodingHTMLEntities;
- (NSString *)stringWithNewLinesAsBRs;
- (NSString *)stringByRemovingNewLinesAndWhitespace;
