解析json字段是一段html串，平常解析出来都能在uiwebview上正常显示，这却出现以下状况，文本内容夹杂好多不需要显示的字符，例如：
NSString*string =@"<span>文本内容</span>";
这就需要处理一下再显示。方法如下：
html=[self htmlEntityDecode :[dict objectForKey:@"data"]];
-(NSString*)htmlEntityDecode:(NSString*)string
{
string =[string stringByReplacingOccurrencesOfString:@""" withString:@"\""];
string =[string stringByReplacingOccurrencesOfString:@"'" withString:@"'"];
string =[string stringByReplacingOccurrencesOfString:@"&" withString:@"&"];
string =[string stringByReplacingOccurrencesOfString:@"<" withString:@"<"];
string =[string stringByReplacingOccurrencesOfString:@">" withString:@">"];
return string;
}
[webView_InformationloadHTMLString:html baseURL:[NSURLURLWithString:@"http://www.maystall.com/"]];
webView_Information.delegate=self;
然后文本内容就正常显示了。
