我想使用新的 iOS 4.0 SDK 在 Facebook 上明确共享一个开放图操作。以下不起作用。它出现在我的事件日志中,但没有出现在我的时间轴上。
// Construct an FBSDKSharePhoto
FBSDKSharePhoto *photo = [[FBSDKSharePhoto alloc] init];
photo.image = img;
photo.userGenerated = YES;
// Create an object
NSDictionary *properties = @{
@"og:type": @"theprose:post",
@"og:title": post.title,
@"og:description": post.text,
@"og:caption": @"A fresh picked Prose for you.",
@"og:url": post.url,
@"fb:explicitly_shared": @"true"
};
FBSDKShareOpenGraphObject *object = [FBSDKShareOpenGraphObject objectWithProperties:properties];
// Create an action
FBSDKShareOpenGraphAction *act = [[FBSDKShareOpenGraphAction alloc] init];
act.actionType = @"theprose:share";
[act setObject:object forKey:@"theprose:post"];
[act setPhoto:photo forKey:@"image"];
// Create the content
FBSDKShareOpenGraphContent *content = [[FBSDKShareOpenGraphContent alloc] init];
content.action = act;
content.previewPropertyName = @"theprose:post";
[[FBSDKShareAPI shareWithContent:content delegate:nil] share];
最佳答案
将此页面的答案拼凑在一起,这对我有用:
<强>1。选中显式共享框
转到您的打开图设置、操作类型,然后选择您的自定义操作。向下滚动到功能部分并确保选中“明确共享”框。
<强>2。设置 fb:explicitely_shared On Action
[action setString:@"true" forKey:@"fb:explicitly_shared"];
<强>3。设置 Action 与对象之间的关系
确保您知道将您的操作与您的对象相关联的正确方法。在这种情况下,关键是“文章”:
[FBSDKShareOpenGraphAction actionWithType:@"mynamespace:share" object:object key:@"article"]
您可以通过查看您在 Facebook 应用的开放图谱设置中创建的操作类型来找到该键。当您通过 Story 将 Action 与 Object 连接时,该关系的新键将出现在 Property Name 列下的 Action 页面上。
当您真正需要的只是该键的 property_name 时,原始海报使用的是 namespace:property_name 格式。这可能是针对 OP 的修复。
<强>4。设置委托(delegate),查找错误
OP 没有利用 FBSDKSharingDelegate 功能。它会报告错误并帮助您解决问题:
[[FBSDKShareAPI shareWithContent:content delegate:self] share];
并在自身中实现委托(delegate)方法:
#pragma mark - FBSDKSharingDelegate
- (void) sharer:(id<FBSDKSharing>)sharer didCompleteWithResults:(NSDictionary *)results {
NSLog(@"Facebook sharing completed: %@", results);
}
- (void) sharer:(id<FBSDKSharing>)sharer didFailWithError:(NSError *)error {
NSLog(@"Facebook sharing failed: %@", error);
}
- (void) sharerDidCancel:(id<FBSDKSharing>)sharer {
NSLog(@"Facebook sharing cancelled.");
}
作为引用,这是我的工作代码
// Create the object
NSMutableDictionary *properties = [NSMutableDictionary dictionaryWithDictionary: @{
@"og:type": @"mynamespace:article",
@"og:title": myModel.title,
@"og:description": @"myModel.description",
@"og:url": @"http://mywebsite.com"
}];
NSURL *imageURL = [myModel getImageURL];
if (imageURL) {
FBSDKSharePhoto *photo = [FBSDKSharePhoto photoWithImageURL:imageURL userGenerated:NO];
[properties setObject:@[photo] forKey:@"og:image"];
}
FBSDKShareOpenGraphObject *object = [FBSDKShareOpenGraphObject objectWithProperties:properties];
// Create the action
FBSDKShareOpenGraphAction *action = [FBSDKShareOpenGraphAction actionWithType:@"mynamespace:share" object:object key:@"article"];
[action setString:@"true" forKey:@"fb:explicitly_shared"];
// Create the content
FBSDKShareOpenGraphContent *content = [[FBSDKShareOpenGraphContent alloc] init];
content.action = action;
content.previewPropertyName = @"article";
// Share the content
FBSDKShareAPI *shareAPI = [[FBSDKShareAPI alloc] init];
shareAPI.shareContent = content;
shareAPI.delegate = self;
[shareAPI share];
