NSString去除所有HTML标签

一般来说，干这种事正则才是王道。不过在ios上执行的效率貌似也高不了多少（第三方类库是在Obj-C的基础上写的），所以弄个一般的方法，基本满足需求就可以了。

废话不多说，直接上代码（google上能找到很多一样的代码） - (NSString *)flattenHTML:(NSString *)html trimWhiteSpace:(BOOL)trim {     NSScanner *theScanner = [NSScanner scannerWithString:html];     NSString *text = nil;       while ([theScanner isAtEnd] == NO) {         // find start of tag         [theScanner scanUpToString:@"<" intoString:NULL] ;                          // find end of tag                  [theScanner scanUpToString:@">" intoString:&text] ;         // replace the found tag with a space         //(you can filter multi-spaces out later if you wish)         html = [html stringByReplacingOccurrencesOfString:                 [ NSString stringWithFormat:@"%@>", text]                                                withString:@""];     }       // trim off whitespace     return trim ? [html stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]] : html;   }
