推荐答案

创建一个对象的数组或字典，表示您要通过JSON发送的信息。完成后，将 -JSONRepresentation 发送到数组/字典。该方法返回一个JSON字符串，然后将其发送到服务器。

Create an array or dictionary of objects representing the information you want to send via JSON. Having done that, send -JSONRepresentation to the array/dictionary. That method returns a JSON string, and you send it to the server.

例如：

NSDictionary *o1 = [NSDictionary dictionaryWithObjectsAndKeys:
    @"some value", @"key1",
    @"another value", @"key2",
    nil];

NSDictionary *o2 = [NSDictionary dictionaryWithObjectsAndKeys:
    @"yet another value", @"key1",
    @"some other value", @"key2",
    nil];

NSArray *array = [NSArray arrayWithObjects:o1, o2, nil];

NSString *jsonString = [array JSONRepresentation];

// send jsonString to the server

执行上面的代码后， jsonString 包含：

After executing the code above, jsonString contains:

[
    {
        "key1": "some value",
        "key2": "another value"
    },
    {
        "key1": "yet another value",
        "key2": "some other value"
    }
]
