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

我不熟悉ios编程。我将数据放入NSDictionary中，然后使用AFJSONRequestSerializer将其序列化为json，然后再将其发送到服务器

现在，如果我的json有简单的结构，比如键->值对，那么我可以很容易地做到，但是如果我的结构是这样的呢-

"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location，location本身就是另一个具有键值对的字典？谢谢。

给你

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，只需将

fullDictionary

序列化如下：

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"];

然后您可以将其转换为JSON，如下所示：

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

文字语法和setObject的丑陋组合，最好选择其中之一。
