//如果soap的返回字符串比较多。需要实现以下这个方法，配合 didReceiveData 方法来正确的接受到所有的soap字符串
//原因是：如果soap的返回字符串比较多。didReceiveData 这个方法会多次被调用。如果把soap解析的功能直接写在didReceiveData这个方法里面。会出现错误。这个时候，就需要 和connectionDidFinishLoading 联用。实现思路是：定义一个类变量NSMutableString * returnSoapXML;用于存放返回的soap字符串。
//一旦有返回内容，获得soap信息,追加到结果字符串中
//-(void) connection:(NSURLConnection *) connection didReceiveData:(NSData *)responseData
//{
// [returnSoapXML appendString:[[NSMutableString alloc] initWithData:responseData encoding:NSUTF8StringEncoding]];
//}
//最后在connectionDidFinishLoading 方法中实现，对完整的soap字符串的业务处理
//数据全部接受成功以后调用
