Obj-C获取JSON密钥名称 [英] Obj-C get JSON key name

问题描述

我正在尝试在PHP和iOS之间创建链接，并且我正在使用JSON.尽管我的JSON数组很奇怪，但我不是创建者，因为它在封闭的API中，所以我无法更改它.

Hi I am trying to create a link between PHP and iOS, and I am using JSON. Although my JSON array is strange, I am not the creator, as this is in a closed API, I cannot change it.

JSON如下:

{"success":true,"errors":[],"data":{"Servers":{"6":"Name here"}}}

6是服务器的ID，另一个是名称.

The 6 is the ID of the server, and the other one is the name.

如您所见，键是ID，值是名称，但是如何在Objective-C中获得ID?我知道如何接收服务器名称，但是要做到这一点，我需要找到服务器ID.

As you can see the key is the ID and the value is the name, but how do I get the ID in Objective-C? I know how to receive the server name, but to do that I need to find the server ID.

这是我当前的代码:

NSDictionary *json = [[NSDictionary alloc] init];
    NSError *error;
    json = [NSJSONSerialization JSONObjectWithData:_responseData options:kNilOptions error:&error];
 NSDictionary *test = [dataDict objectForKey:@"Servers"]
            NSLog(@"%@", [test objectForKey:@"6"]); // Server Name (ID of server is 6)

_responseData仅仅是从PHP脚本接收到的JSON数据.

_responseData is just the JSON data received from the PHP script.

推荐答案

您将执行以下操作:

[test enumerateKeysAndObjectsUsingBlock:^(NSString* serverId, NSString *serverName, BOOL *stop) {
    // Process data here.
}];
