iphone sdk xcode程序中如何调用web service?

[happy0022]

现在我有一个MyEclipse 6.0 java写的web service，不知道该怎么在我的iphone程序中调用。还请高手指点！最好有代码示例。谢谢了。

用HTTP接口自己封装就可以了

[happy0022]

可以在详细点吗？ 初学iphone 不是很明白

[Defonds]

应该有接口。

请问楼主，这个问题解决了吗，我也遇到同样的问题，可以帮忙吗？谢谢了～～我想用soap，但是刚刚接触iphone不是很了解！

有两种方法生成SOAP本地代理类
1:使用WSDL2OBJC.exe，生成SOAP代理类，引入工程中。
2:访问http://sudzc.com/，在线提交服务地址或者上传WSDL文件，返回SOAP代理类，引入工程中。

谢谢。。。。

其实从服务器上获取数据，除了使用webservice以外，也可以向服务器发送http请求，让服务器端返回一个比较好处理的格式，如JSON，并且在iphone os下有专门的处理 Json格式的类库，通过该类库我们可以很容易的将获取的json格式序列化成objective-c下的NSArray or NSDictionary 对象。

[ReyZhang]

调用webservice 需要我们组装soap请求信息，维护不方便。
iphone os也有比较优秀的封装好的处理http请求的类库ASIHttpRequest，通过该类库可以很easy的实现与服务器的交互。

能不能给我一些范例？？我初学IPHONE 都不知应该怎样开始

[飞鱼是我]

同求示例源码！lz弄好的话麻烦发一份给我，先谢了！[e-mail]

[yy7074]

我也想要一份 实例代码，楼主谢谢啦～～哪位大哥有的话麻烦发一份呀～[e-mail]

[程序员小迷]

不直接用系统的http类即可么，有这么复杂吗
