我对编写一般代码很陌生，我需要一些帮助将Python脚本转换为iOS应用程序的OBJ-C

我有一个python脚本在网桥上运行XMLRPC服务器

我有一个用Xcode4编写的iOS应用程序，当按下按钮时需要调用网桥上运行的python脚本

我还有一个用Python编写的XMLRPC客户端脚本，可以访问XMLRPC服务器

基本上，我需要将Python XMLRPC客户端脚本转换为OBJ-C，以便在iOS应用程序上运行它

Python XMLRPC客户端脚本：

类型“exceptions.ValueError”：串行接口类型必须为整数

现在我只需要弄清楚如何将“1”声明为整数，然后同时传递and integer和字符串。到目前为止，我尝试的每件事都给了我一个糟糕的解释…

你不能在iOS设备上调用脚本。您可以在OS X中使用，但不能在（AppStore批准的）iOS应用中使用。

我猜您需要创建一个包含参数的数组：

NSArray *args = [NSArray arrayWithObjects:ourAddr, dev, nil];

然后将其传递给XMLRPCRequest：

[waitOnEvent setMethod:@"connectSerial" withObject:args];

哇！我发誓我已经试过了。像洛克这样的人更接近于答案。所以它几乎传递了正确的论点。。。刚刚添加了[]和“”，谢谢你的帮助，我很感激！这是我从Python服务器得到的信息：17:19:27:579 INFO http_Server connectSerial（['1'，'/dev/ttylS1']）17:19:27:600 INFO http_Server 192.168.0.x:52626--“POST/http/1.1”200 479 17:19:27:607 INFO http_Server faultCode 1 faultString type“exceptions.TypeError”：connectSerial（）至少有3个参数（2给出）@swbooking如果这个答案正是你想要的，点击答案左侧出现的大“V”将其标记为正确答案：）这样你就不能从你的应用程序调用另一台服务器上运行的脚本了？真的，我只需要这个作为测试。最终，网桥应该连接到web服务器，应用程序将只显示数据。谢谢你的帮助！我的错。我浏览了你的密码。您无法在设备上调用它。您想查找使用NSURL/NSURLRequest/NSURLConnection调用POST方法的示例。太好了！我会查的。再次感谢！
