Question

我是ios编程的新手。我将数据放在NSDictionary中，然后在将其发送到服务器之前使用AFJSONRequestSerializer序列化为json。

现在，如果我的json具有像key这样简单的结构 - >价值对，然后我可以很容易地做到，但如果我的结构是这样的 -

"person" =     (
                {
                    "location" =             {
                        city = "Manila";
                        Country = "Phillipines";
                    };
            image = "http://mymanila.com/1.png";
            link ="http://mymanila.com/1.html"
        }
    );

我的问题是如何放置位置，它本身是另一个带键值对的字典？感谢。

Answer 1

你走了。

NSDictionary *locationDictionary = @
{
    @"city" : @"Manila",
    @"Country" : @"Phillipines"
};


NSDictionary *personDictionary = @
{
    @"location" : locationDictionary,
    @"image" : @"http://mymanila.com/1.png",
    @"link" : @"http://mymanila.com/1.html"
};

NSDictionary *fullDictionary = @
{
    @"person" : personDictionary
};

现在，只需序列化fullDictionary。

Answer 2

像这样：

NSMutableDictionary* person = [NSMutableDictionary dictionary];

NSDictionary* location = @{@"city":@"Manila", @"Country":@"Phillipines"};
[person setObject:location forKey:@"location"];
[person setObject:@"http://mymanila.com/1.png" forKey:@"image"];
[person setObject:@"http://mymanila.com/1.html" forKey:@"link"];

然后你可以将它转换为JSON，如下所示：

NSData *dictData = [NSKeyedArchiver archivedDataWithRootObject:person];
id jsonObject = [NSJSONSerialization JSONObjectWithData:dictData options:NSJSONReadingMutableContainers error:nil];

如何在序列化为json之前将NSDictionary添加到另一个NSDictionary
