我尝试将图像共享到 Facebook,并且我需要应用程序名称位于 Facebook 的共享帖子中
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 Facebook 预览页面,其中包含我添加的图像:
这是我的 Facebook 墙上的帖子,没有图片:
我做错了什么?
最佳答案
取消注释此行:
// @"og:image": @[photo],
并评论这个:
[action setArray:@[photo] forKey:@"image"];
这样您将同时显示图像、标题和说明。
一点说明:照片对象必须是字符串 URL
就我而言,这是生成的代码:
// 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);
}
