我在将 Box iOS SDK 与我的项目集成时遇到问题。我已按照https://github.com/box/box-ios-sdk-v2上的说明进行操作，并且我的应用已成功通过身份验证。现在，我被困在第一部分的制作 API 调用部分（获取文件夹的子项）。我的骨架应用程序现在基本上只有两个按钮：（1）链接；(2) 生孩子。链接后，它要求登录box.com；我愿意; 然后它回到一个空屏幕。然后，我必须再次运行程序，然后点击 get children。我试图查看此链接（iOS Box SDK BoxFolder.children 始终为零）和其他问题以找到解决方案，但未能。以下是每个人的例程：

- (IBAction)linkAction:(id)sender {

    UIViewController *authorizationController = [[BoxAuthorizationViewController alloc] initWithAuthorizationURL:[[BoxSDK sharedSDK].OAuth2Session authorizeURL] redirectURI:nil]; 
    [self presentViewController:authorizationController animated:YES completion:nil]; 
}

- (IBAction)getChildrenAction:(id)sender { 

    BoxCollectionBlock success = ^(BoxCollection *collection) 
    { 
        dispatch_sync(dispatch_get_main_queue(), ^{ 
            NSLog(@"CHILDREN SUCCESS!!!"); 
        }); 
    }; 

    BoxAPIJSONFailureBlock failure = ^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, NSDictionary *JSONDictionary)
    {

        dispatch_sync(dispatch_get_main_queue(), ^{ 
            // handle errors 
            NSLog(@"CHILDREN ERROR, error = %@", error); 
        }); 
    }; 

    NSString *folderID = BoxAPIFolderIDRoot; 

    [[BoxSDK sharedSDK].foldersManager folderItemsWithID:folderID requestBuilder:nil success:success failure:failure]; 

}

这是链接后的成功输出：

我在 box.com 的基本目录中有文件。如果有人能帮助我解决这个问题，我将不胜感激。我一直在尝试明确地遵循说明。或者，如果您需要更多信息来诊断此问题，请告诉我。非常感谢。

你的错误代码是 20002 代表这个状态

访问令牌已过期并且操作无法重新入队，因为它之前已经重新入队。

这来自 box API GIT 文档，因此您在执行此操作时应确保您的访问令牌有效。

另外，看看文件夹选择器你应该做这样的事情：

   if ([BoxSDK sharedSDK].OAuth2Session.isAuthorized)
{
    // in order to avoid a short lag, jump immediatly to the file picker if we are already authorized
    [self presentBoxFolderPicker];
}
else
{
    BoxFolderBlock success = ^(BoxFolder * folder) {
        [self presentBoxFolderPicker];
    };
    BoxAPIJSONFailureBlock failure = ^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, NSDictionary *JSONDictionary){
        [self boxError:error];
    };
    // try sending a hearbeat
    [[BoxSDK sharedSDK].foldersManager folderInfoWithID:BoxAPIFolderIDRoot
                                         requestBuilder:nil
                                                success:success
                                                failure:failure];
}
