FBSDKSharingDelegate 回调不起作用，即使 post 工作正常

Question

FBSDKSharingDelegate 回调无效。 我可以 post 使用 ios SDK 正常访问 facebook，但我想检测是否 post 成功并采取其他操作通知用户。但是，回调对我不起作用。委托方法没有被调用，我不知道为什么。

使用 ios8，Parse 作为我的后端。在 Parse 中，用户 linked 到 FB。我正在使用 IOS 模拟器。

我尝试过的：我已确保向 Parse 用户授予、保存和 link 发布权限。我已经运行检查并检测到 "publish_actions" 正常。 posting 工作正常，因为我可以在 facebook 帐户上看到 post。只是回调不起作用。我检查了我的 fb 设置，看起来不错。为了在最底部进行良好的衡量，我已经包含了来自我的应用程序委托的相关代码。我已经用 XXXX 屏蔽了机密密钥。

代码：

1st：查看用户是否登录到 Parse，如果没有，请发送登录并 link 到 facebook 帐户。完成后，我向 Parse 用户请求 "publish" 权限和 link 额外权限。我知道这在我重新编译时有效 b/c，它会记住 "publish" 权限并直接进入 post.

    PFUser *currentUser = [PFUser currentUser];
    if(!currentUser) {
        [self pushToSignIn];
    } else if(![PFFacebookUtils isLinkedWithUser:currentUser]){
        [self linkUserToFacebook:currentUser];
        NSLog(@"user account not linked to facebook");
    } else {
        [self shareSegmentWithFacebookComposer];
    }
}


-(void)linkUserToFacebook:currentUser{

    [PFFacebookUtils linkUserInBackground:currentUser withPublishPermissions:@[@"publish_actions"] block:^(BOOL succeeded, NSError *error) {
        if(error){
            NSLog(@"There was an issue linking your facebook account. Please try again.");
        }
        else {
            NSLog(@"facebook account is linked");
            //Send the facebook status update
            [self shareSegmentWithFacebookComposer];
        }
    }];
}


-(void)shareSegmentWithFacebookComposer{
if ([[FBSDKAccessToken currentAccessToken] hasGranted:@"publish_actions"]) {
    [self publishFBPost]; //publish
} else {
    NSLog(@"no publish permissions"); // no publish permissions so get them, then post


    [PFFacebookUtils linkUserInBackground:[PFUser currentUser]
                   withPublishPermissions:@[ @"publish_actions"]
                                    block:^(BOOL succeeded, NSError *error) {
                                        if (succeeded) {
                                            NSLog(@"User now has read and publish permissions!");
                                            [self publishFBPost];
                                        }
    }];

这里是制作post的地方：

-(void) publishFBPost{
        FBSDKShareLinkContent *content = [FBSDKShareLinkContent new];
        content.contentURL = [NSURL URLWithString:[self.selectedSegment valueForKey:@"linkToContent"]];
        content.contentTitle = [self.selectedProgram valueForKey:@"programTitle"];
        content.contentDescription = [self.selectedSegment valueForKey:@"purposeSummary"];

    PFFile *theImage = [self.selectedSegment valueForKey:@"segmentImage"];
    NSString *urlString = theImage.url;
    NSURL *url = [NSURL URLWithString:urlString];
    content.imageURL = url;

    FBSDKShareDialog *shareDialog = [FBSDKShareDialog new];

    [shareDialog setMode:FBSDKShareDialogModeAutomatic];
//    [FBSDKShareDialog showFromViewController:self.messageTableViewController withContent:content delegate:self];
    [shareDialog setShareContent:content];
    [shareDialog setDelegate:self];
    [shareDialog setFromViewController:self.messageTableViewController];
    [shareDialog show];
}

下面的委托方法无效。意思是 post 完成后，我可以在 FB 帐户上看到它，但是 none 这些委托方法执行。

#pragma mark - delegate methods

- (void)sharer:(id<FBSDKSharing>)sharer didCompleteWithResults:(NSDictionary *)results {
//    if ([sharer isEqual:self.shareDialog]) {
        NSLog(@"I'm going to go crazy if this doesn't work.%@",results);

        // Your delegate code
//    }
}

    - (void)sharer:(id<FBSDKSharing>)sharer didFailWithError:(NSError *)error
    {
        NSLog(@"sharing error:%@", error);
        NSString *message = error.userInfo[FBSDKErrorLocalizedDescriptionKey] ?:
        @"There was a problem sharing, please try again later.";
        NSString *title = error.userInfo[FBSDKErrorLocalizedTitleKey] ?: @"Oops!";

        [[[UIAlertView alloc] initWithTitle:title message:message delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil] show];
    }

    - (void)sharerDidCancel:(id<FBSDKSharing>)sharer
    {
        NSLog(@"share cancelled");
    }

控制台输出： posting 后我收到的唯一消息是几秒钟后出现此消息：

plugin com.apple.share.Facebook.post invalidated

请帮忙！

Answer 1

我想我回答这个问题为时已晚，但其他人也可能陷入其中，这就是分享我的知识的原因。

As per Facebook API documentation

sharer:didCompleteWithResults: Sent to the delegate when the share completes without error or cancellation.
The results from the sharer. This may be nil or empty.

可能是因为此委托方法仅在 post 成功共享时才被调用。如果失败，另一个委托方法 sharer:didFailWithError: 将被调用。我认为 Facebook API 应该不需要添加 result 参数。

所以根据我的经验，如果 sharer:didCompleteWithResults 每当调用它就意味着成功。
