项目中用到soap协议调 webservice的接口，记录下
.h文件里
@property (strong, nonatomic) NSMutableData *xmlData;
@property (strong, nonatomic) NSMutableData *webData;
@property (strong, nonatomic) NSMutableString *soapResults;
@property (strong, nonatomic) NSXMLParser *xmlParser;
@property (nonatomic) BOOL elementFound;
@property (strong, nonatomic) NSString *matchingElement;
@property (strong, nonatomic) NSURLConnection *conn;
.m文件里
在@implementation下面写
@synthesize webData;
@synthesize soapResults;
@synthesize xmlParser;
@synthesize elementFound;
@synthesize matchingElement;
@synthesize conn;

// 设置我们之后解析XML时用的关键字，与响应报文中Body标签之间的getMobileCodeInfoResult标签对应

// 创建SOAP消息，内容格式就是网站上提示的请求报文的实体主体部分
