Facebook iOS SDK:无法使用 FBRequest 的 requestForUploadPhoto 指定相册: [英] Facebook iOS SDK: Cannot specify an album using FBRequest's requestForUploadPhoto:

问题描述

我的 iPhone 应用中有一张本地照片，我想将它上传到 Facebook 上专门用于我的应用的特定相册.

I have a local photo in my iPhone app, and I want to upload it to a specific album on Facebook dedicated to my app.

问题:我的应用名称以照片"一词结尾，因此默认的 Facebook 相册是 APP_NAME 照片照片 - 显然有问题.

Problem: My app name ends with the word 'Photos', so the default Facebook album is APP_NAME Photos Photos - obviously a problem.

目标:我想创建一个新相册，将其 ID 存储在 NSUserDefaults 中，并且(在运行时进行一些验证后)将其用于以后上传的所有照片应用程序.

Goal: I want to create a new album, store its ID in NSUserDefaults, and (after some validation at runtime) use it for all future photos being uploaded from the app.

我在哪里:我可以通过 Open Graph 制作新专辑，使用我想要的名称和描述，我可以检索它的 ID.我也可以很容易地上传照片.但是，我无法弄清楚如何指定上传的照片的最终位置！

Where I'm at: I can make the new album via Open Graph, using my desired name and description, and I can retrieve its ID. I can also upload photos easily enough. However, what I CANNOT figure out is how to specify where that uploaded photo ends up!

代码:这是我的照片上传代码，其中一些结果被注释.我假设这是我的问题所在，因为相册创建等工作正常.

Code: Here's my photo upload code with some results commented in. I'm assuming this is where my problem is, since album creation, etc, is working perfectly.

- (void)postPhotosToFacebook:(NSArray *)photos withAlbumID:(NSString *)albumID {

    // Just testing with one image for now; I'll get in to multiple later..
    UIImage *image = [photos lastObject];

    FBRequest *imageUploadRequest = [FBRequest requestForUploadPhoto:image];

    // CALL OUT: I'm guessing my problem is here - but I just don't know!
    [[imageUploadRequest parameters] setValue:albumID
                                       forKey:@"album"];

    DebugLog(@"imageUploadRequest parameters: %@",[imageUploadRequest parameters]);

    // Results of DebugLog:
    // imageUploadRequest parameters: {
    //     album = 10151057144449632;
    //     picture = "<UIImage: 0xc6b6920>";
    // }
    // The album data returns correctly using FB's Graph API explorer tool,
    // so I know it's a legit album.
    // https://developers.facebook.com/tools/explorer

    FBRequestConnection *connection = [[FBRequestConnection alloc] init];

    [connection addRequest:imageUploadRequest
         completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {

             if (!error) {

                 DebugLog(@"Photo uploaded successfuly! %@",result);

                 // Results of DebugLog:
                 // 
                 // Photo uploaded successfuly! {
                 //     id = 10151057147399632;
                 //     "post_id" = "511304631_10151057094374632";
                 // }
                 // Again, the photo at that ID shows up correctly, etc -
                 // BUT it's in the wrong album! It shows up in the default app album.

             } else {

                 DebugLog(@"Photo uploaded failed :( %@",error.userInfo);
             }

         }];

    [connection start];

}

猜测:我猜我的问题在于我如何将我的相册 ID 参数分配给图像请求......但我不知道.

Guesses: I'm guessing my problem is somewhere in how I'm assigning my album ID parameter to the image request.. but I have no clue.

您可以在 这个 URL 这应该是可能的..

You can see at this URL that this should be possible..

推荐答案

Ahh SWEET.我通过一些老式的、直接的修补来解决这个问题.

Ahh SWEET. I figured this one out with some good old-fashioned, straight-up tinkering.

鉴于没有关于如何将专辑"值应用于 FBRequest 的真正说明，我犹豫将其称为错误，但无论哪种方式，我都需要一种不同的方法 - 在这种情况下，只需创建一个通用的 Open GraphHTTP请求并填写所有图片信息.

Given that there is no real instruction on how to apply the 'album' value to an FBRequest, I hesitate to call it a bug, but either way I needed a different method - in this case, simply creating a generic Open Graph HTTP request and filling in all the image info.

这种方法没有真正的缺点；除了您不能使用 requestForUploadPhoto: 便捷方法.

There is no real downside to this approach; except that you can't use the requestForUploadPhoto: convenience method.

这里是我对正确方法的实现(删除的代码被注释掉了):

Here is my implementation of the correct method (removed code is commented out):

- (void)postPhotosToFacebook:(NSArray *)photos withAlbumID:(NSString *)albumID {

    UIImage *image = [photos lastObject];

//    FBRequest *imageUploadRequest = [FBRequest requestForUploadPhoto:image];
//    
//    [[imageUploadRequest parameters] setValue:albumID
//                                       forKey:@"album"];
//    
//    DebugLog(@"imageUploadRequest parameters: %@",[imageUploadRequest parameters]);

    NSString *graphPath = [NSString stringWithFormat:@"%@/photos",albumID];

    DebugLog(@"graphPath = %@",graphPath);

    NSDictionary *parameters = [NSDictionary dictionaryWithObjectsAndKeys:
                                image,@"picture",
                                nil];

    FBRequest *request = [FBRequest requestWithGraphPath:graphPath
                                              parameters:parameters
                                              HTTPMethod:@"POST"];

    FBRequestConnection *connection = [[FBRequestConnection alloc] init];

    [connection addRequest:request
         completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {

             if (!error) {

                 DebugLog(@"Photo uploaded successfuly! %@",result);

             } else {

                 DebugLog(@"Photo uploaded failed :( %@",error.userInfo);
             }

         }];

    [connection start];

}
