使用 FBSDKShareOpenGraphObject 将文章分享到 Facebook 后看不到图像

Question

我尝试将图片分享到 Facebook，我需要应用程序名称在 Facebook 的共享 post 中

这是代码：

FBSDKSharePhoto *photo = [[FBSDKSharePhoto alloc] init];
UIImage *image1 = [GeneralMethods imageConvertToSizeWithImage:postImageView.image scaledToWidth:300];
photo.image = [UIImage imageNamed:@"VImage.png"];
photo.userGenerated = YES;

NSDictionary *properties = @{
                             @"og:type": @"article",
                             @"og:title": @"new item",
                             @"og:description": @"bla bla",
//                                 @"og:image": @[photo],
                             };
FBSDKShareOpenGraphObject *object = [FBSDKShareOpenGraphObject objectWithProperties:properties];



//    [object setPhoto:photo forKey:@"og:image"];

// Create an action
FBSDKShareOpenGraphAction *action = [[FBSDKShareOpenGraphAction alloc] init];
action.actionType = @"news.publishes";


[action setObject:object forKey:@"article"];


// Add the photo to the action. Actions
// can take an array of images.
[action setArray:@[photo] forKey:@"image"];

// Create the content
FBSDKShareOpenGraphContent *content = [[FBSDKShareOpenGraphContent alloc] init];
content.action = action;
content.previewPropertyName = @"article";

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

这是我添加图片的 Facebook 预览页面：

这是我 Facebook 墙上的 post 没有图像 :

我做错了什么？

Answer 1

取消注释此行：

//                                 @"og:image": @[photo],

并评论这个：

[action setArray:@[photo] forKey:@"image"];

像这样，您将同时显示图片、标题和描述。

注意一点：照片object必须是字符串URL

在我的例子中，这是结果代码：

// Create an object  
NSDictionary *properties = @{
                             @"og:type": @"article",
                             @"og:url": @"https://the_link_you_want.com",
                             @"og:title": @"your title",
                             @"og:description": @"your description",
                             @"og:image": @"http://url_to_your_image"
                             };

FBSDKShareOpenGraphObject *object = [FBSDKShareOpenGraphObject  objectWithProperties:properties];

// Create an action
FBSDKShareOpenGraphAction *action = [[FBSDKShareOpenGraphAction alloc] init];
action.actionType = @"news.publishes";

[action setObject:object forKey:@"article"];

// Create the content
FBSDKShareOpenGraphContent *content = [[FBSDKShareOpenGraphContent alloc] init];
content.action = action;
content.previewPropertyName = @"article";


FBSDKShareDialog *shareDialog = [[FBSDKShareDialog alloc] init];
shareDialog.fromViewController = self;
shareDialog.shareContent = content;
[shareDialog show];

if (![shareDialog canShow]) {
    // update the app UI accordingly
}
NSError *error;
if (![shareDialog validateWithError:&error]) {
    NSLog(@"FB Error: %@", error);
}
