Question

所以在一个块中我得到并解析一个看起来像这样的JSON对象（任何时候你看到＆＃34;＆lt; ...＆gt;＆＃34;假设正确形成的数据）（这也只是一个）有问题的对象）：

{
    asset =         {
        <...>
    };
    <...>
    sections =         (
                    {
            <...>
            fields =                 (
            );
            items =                 (
            );
        },
                    {
            <...>
            fields =                 (
            );
            items =                 (
            );

        },
                    {
            <...>
            fields =                 (
            );
            items =                 (
                                    {
                    <...>
                    properties =                         {
                        title = "We welcome guests...";
                    };
                },
                                    {
                    <...>
                    properties =                         {
                        title = "More text";
                    };
                },
                                    {
                    <...>
                    properties =                         {
                        title = "Opportunity Insert...";
                    };
                }
            );
        },
                    {
            <...>
            fields =                 (
                                    {
                    <...>
                    values =                         (
                        Private,
                        Public
                    );
                },
                                    {
                    <...>
                    values =                         (
                    );
                },
                                    {
                    <...>
                    values =                         (
                    );
                }
            );
            items =                 (
            );
        },
                    {
            <...>
            fields =                 (
                                    {
                    <...>
                    values =                         (
                    );
                },
                                    {
                    <...>
                    values =                         (
                    );
                }
            );
            items =                 (
            );
        }
    );
}

获得此代码的代码（使用AFNetworking）：

NSMutableURLRequest* req = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:AppsURL([[NSUserDefaults standardUserDefaults] objectForKey:kAuthToken])]];

AFHTTPRequestOperation* op = [[AFHTTPRequestOperation alloc] initWithRequest:req];
[op setResponseSerializer:[[AFJSONResponseSerializer alloc] init]];
[op setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
    if (responseObject != nil&&[responseObject isKindOfClass:[NSDictionary class]]) {
        NSDictionary* dict = (NSDictionary*)responseObject;
        if (dict[@"apps"]&&[dict[@"apps"] isKindOfClass:[NSArray class]]) {
            apps = dict[@"apps"];

            dispatch_async(dispatch_get_main_queue(), ^{
                [self.tableView reloadData];
            });
            return;
        }

    }
        NSLog(@"Error Loading apps:%@",responseObject);

} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Error:%@",error);
    NSLog(@"Response:%@",operation.response.description);

}];

[op start];

此时一切都在加载到内存中并且工作正常。我将其设置为类级NSArray，然后使用该NSArray填充表。当用户从表中选择一个项目后尝试检索数据时，问题就出现了。然后我使用索引并从NSArray中拉出该对象以找到看起来像这样的东西（注意所有项目和字段数组现在都是空的）：

{
asset =     {
    <...>
};
<...>
sections =     (
            {
        <...>
        fields =             (
        );
        items =             (
        );
    },
            {
        <...>
        fields =             (
        );
        items =             (
        );
    },
            {
        <...>
        fields =             (
        );
        items =             (
        );
    },
            {
        <...>
        fields =             (
        );
        items =             (
        );
    }
);
}

选择代码：

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
  if (indexPath.row < apps.count) {
    //the output of this is what I copy and pasted
    NSLog(@"app data to be cleaned up:%@ \r app data sent:%@",apps[indexPath.row],((NSDictionary*)apps[indexPath.row]).mutableCopy);

    //I originally thought the problem was here, but the output above proved me wrong
    NSMutableDictionary *app = [Functions recurseDictionaryForNull:((NSDictionary*)apps[indexPath.row]).mutableCopy];

    [[NSUserDefaults standardUserDefaults] setObject:app
                                              forKey:@"app"];

    MainMenuViewController* mainMenu = (MainMenuViewController*)[self.storyboard instantiateViewControllerWithIdentifier:@"mainMenu"];

    [self.navigationController setViewControllers:@[mainMenu] animated:YES];// reset nav stack
  }
}

我有点失败......任何想法可以做到这一点以及如何解决它？

这是来自服务器的数据。我被告知2“应用程序”是相同的，除了一个项目，结果他们也缺少所有的字段和项目。感谢迪马和迈克不管怎样的时间！
