Ios XML-RPC请求Wordpress

从xmlrpc服务器响应对象中获取

术语中的
名称
（我博客文章类别的名称）的值没有问题

服务器响应：

responseArray: ( 
    { guid = "http://www.domain.com/wp/?p=12";
      "post_id" = "123";
      terms = (
          { name = "Uncategorized"; }
      );
    }

)

。。。使用以下几行Objective-C代码：

NSMutableArray *responseArray = [[NSMutableArray alloc] init];
responseArray = [nodeSaveResponse object];

for(i = 0; i < responseArray.count; i++) {

    NSString *postLink = [[responseArray objectAtIndex: i] valueForKey: @"guid"];
    NSString *postId = [[responseArray objectAtIndex: i] valueForKey: @"post_id"];

    NSMutableArray *catArray = [[NSMutableArray alloc] init];
    catArray = [[responseArray objectAtIndex: i] valueForKey: @"terms"]];
    NSArray *cat = [catArray valueForKey: @"name"];
    NSString *myCatString = [cat objectAtIndex: 0];
}

知道我的错在哪里吗

干杯，马丁

NSString *myCatString = @"MyCategory";
NSMutableDictionary *name = [[NSMutableDictionary dictionaryWithObjectsAndKeys: myCatString, @"name", nil];
NSMutableArray *catArray = [[NSMutableArray arrayWithObject: name];

NSMutableDictionary *values = [[NSMutableDictionary alloc] init];
[values setObject: title forKey: @"post_title"]; 
// and so on with other values - until here everything works well
[values setObject: catArray forKey: @"terms"]; // if this line is called, the request fails

NSArray *params = [NSArray arrayWithObjects: @"1", user, pass, values, nil];
[myRequest setMethod: @"wp.newPost" withParameter: params];
