ios 调用webservice 辅助类

类还在修改中，现只是用控制台进行调试。之后再加上结果的解析。初学objc几天，这里只作学习笔记。欢迎指正.不是不写备注，是不喜欢写备注。

调用：我别外写了一个WSClient类，对应Web端的方法。

Bsoap *bsoap = [[Bsoap alloc]initWithNameSpaceAndEndPoint:@"http://yourNamespace"
                                               StrEndPoint:@"http://xxx.asmx"];

 [bsoapSetMethod:@"SearcheBook"];

 [bsoapAddParam:@".net"Keys:@"keyWord"];  

 [bsoap AddParam:@"2" Keys:@"pageNo"];  

 NSString *strsoap = [bsoap CnnWebService];

 

 这样就完成一次调用了。先创建Bsoap对象，然后设置方法，添加参数，多个就添加多次。然后调用CnnWebService。就可以返回结果。
