我还尝试使用WPXMLRPC框架->

使用此代码：

WPXMLRPCDecoder *decodedWPXML = [[WPXMLRPCDecoder alloc] initWithData:XMLcontent];
if ([decodedWPXML isFault]) {
    NSLog(@"XML-RPC error %ld: %@", (long)[decodedWPXML faultCode], [decodedWPXML faultString]);
} else {
    NSLog(@"XML-RPC response: %@", [decodedWPXML object]);
}

我设法接收一个对象，我可以通过NSLog（@“%@”，object）输出该对象；但我无法进一步处理通过这种方式收到的任何数据。我对objective-c很陌生（可能对某些人来说很明显）。我也看过官方的wordpress for iOS应用程序，但我无法使用任何代码

任何帮助都将不胜感激，我不介意使用任何不同的框架/技术等。如果它们有助于获得我的解决方案。

我很高兴，它是免费的。您可以轻松地将请求微调到特定的页面和帖子类型，这是有据可查的。您从站点得到的总是JSON（优于XML；）中的字典和数组结构。检查JSON结构的好方法是

一些开始使用的示例代码

为我提供一个包含所有post成员的数组，我可以通过该数组进行迭代

谢谢你的帮助。
我打开了一篇关于这个主题的新帖子，提出了一个更详细的问题，因为我发现这是一个完全不同的问题，因为它在GDATEXML上比在WordPressXML上更重要
on幸运的是，通过这种方式我无法获得菜单顺序，菜单顺序取消了在wordpress后端对帖子进行手动排序的功能。WPXMLRPCDecoder似乎也返回json代码，但它只是保存为一个对象（实际上是一个NSobject），是否有办法将其转换为NSDictionary？NSobject只是NSDictionary的超类。返回对象的处理是示例代码的一部分，请参见//handle response下的。有一种检查retu的方法
