iOS、Facebook、GraphAPI 问题

Question

我需要允许用户从 iOS 应用程序在 Facebook 上发布信息，以下几乎是我想要的，但是:

1. 我显然不想要 ISBN，因为应用程序中的信息(实际上是另一个用户的帖子)不是可以描述为“书”并且没有 ISBN 的信息
2. 我需要以某种方式附上应用程序的 Logo 。现在它仅显示为脚注。我只能附上一张图片，但需要第二张图片，即 Logo 。

任何人都可以建议我应该使用什么其他模式，如果不是可以正确表达意义的“books.book”:“用户 A 阅读(或喜欢)用户 B 的帖子”。

这就是 FB 帖子现在的样子:

我为此使用的代码如下:

NSString *title = self.currSelecectedContextCell.uploaderDemoLabel.text;
NSURL *imageURL = self.currSelecectedContextCell.upload.screenshotURL;
NSString *description = self.currSelecectedContextCell.contextLabel.text;
NSDictionary *properties = @{
                             @"og:type": @"books.book",
                             @"og:title": title,
                             @"og:image": imageURL,
                             @"og:description": description,
                             @"books:isbn": @"0-553-57340-3",
                             };
FBSDKShareOpenGraphObject *object = [FBSDKShareOpenGraphObject objectWithProperties:properties];

// Create an action
FBSDKShareOpenGraphAction *action = [[FBSDKShareOpenGraphAction alloc] init];
action.actionType = @"books.reads";
[action setObject:object forKey:@"books:book"];

FBSDKShareOpenGraphContent *content = [[FBSDKShareOpenGraphContent alloc] init];
content.action = action;
content.previewPropertyName = @"books:book";

[FBSDKShareDialog showFromViewController:self
                             withContent:content
                                delegate:nil];

Answer 1

通过以下方式解决:

NSString *title = self.currSelecectedContextCell.uploaderDemoLabel.text;
NSURL *imageURL = self.currSelecectedContextCell.upload.screenshotURL;
NSString *description = self.currSelecectedContextCell.contextLabel.text;
NSDictionary *properties = @{
                             @"og:type": @"object",
                             @"og:url":@"http://www.textpertapp.co/",
                             @"og:title": title,
                             @"og:image": imageURL,
                             @"og:description": description
                             };
FBSDKShareOpenGraphObject *object = [FBSDKShareOpenGraphObject objectWithProperties:properties];

// Create an action
FBSDKShareOpenGraphAction *action = [[FBSDKShareOpenGraphAction alloc] init];
action.actionType = @"og.likes";
[action setObject:object forKey:@"object"];

FBSDKShareOpenGraphContent *content = [[FBSDKShareOpenGraphContent alloc] init];
content.action = action;
content.previewPropertyName = @"object";

[FBSDKShareDialog showFromViewController:self
                             withContent:content
                                delegate:nil];
