标题: ios - JSON解析UITableViewController

我正在尝试将我的 JSON 数据传递到 UITableViewController。我确实设法将我的一个 JSON 传递到 UITableView 并在用户执行 egue 时将其显示在下一个 ViewController 上。问题是我得到了 4 个 JSON 数据，我希望它显示在 ViewController 上。由于我的 JSON 格式，我无法执行 ObjectForKey。

这是我的 JSON

{
    uid: "60",
    name: "pae1344",
    mail: "[email protected]",
    theme: "",
    signature: "",
    signature_format: "plain_text",
    created: "1396189622",
    access: "0",
    login: "1396189622",
    status: "1",
    timezone: "Asia/Bangkok",
    language: "",
    picture: "0",
    init: "[email protected]",
    data: null,
    uri: "http://localhost/drupal/rest/user/60"
},

这是来自 myTableViewController 的代码。

#import "TestinViewController.h"
#import "AFNetworking.h"
#import "TestinCell.h"
#import "EDscriptionViewController.h"
@interface TestinViewController ()

@end

@implementation TestinViewController

有没有办法让我的 JSON 变成字典，所以我可以使用 ObjectForKey 选择要显示的内容？

Best Answer-推荐答案

首先通过将 .m 和 .h 文件添加到您的项目来使用此库:

JSONKit

然后您可以将 JSON 字符串转换为字典。

//JSONString is a NSString variable with the JSON
NSDictionary *myJSONDic = [JSONString objectFromJSONString]
NSLog(@"User Id is : %@",[myJSONDic valueForKey"uid"]);
