我试图使用stories向Facebook发布一个带有动作的开放图谱对象，但我总是收到一个没有任何细节的错误。我将我正在使用的所有代码总结成一个单独的方法，供大家参考：
- (void)publishToGraph {
NSMutableDictionary<FBOpenGraphObject> *object = [FBGraphObject openGraphObjectForPost];
object.provisionedForPost = YES;
object[@"title"] = @"Example title";
object[@"type"] = @"rs-coupcash";
object[@"description"] = @"Example description";
object[@"url"] = @"http://exampleurl.com/idk";
object[@"image"] = @[@{@"url": @"http://exampleurl.com/example_url.png", @"user_generated" : @"true" }];
[FBSession openActiveSessionWithPublishPermissions:@[@"email", @"public_profile", @"publish_actions"] defaultAudience:FBSessionDefaultAudienceFriends allowLoginUI:YES completionHandler:^(FBSession *session, FBSessionState state, NSError *error) {
if (!error && state == FBSessionStateOpen) {
[FBRequestConnection startForPostOpenGraphObject:object completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
if(!error) {
NSString *objectId = [result objectForKey:@"id"];
NSLog(@"Object ID: %@", objectId);
id<FBOpenGraphAction> actionObject = (id<FBOpenGraphAction>)[FBGraphObject graphObject];
[actionObject setObject:objectId forKey:@"coupon"];
[FBRequestConnection startForPostWithGraphPath:@"/me/rs-coupcash:favorite" graphObject:actionObject completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
[[FBSession activeSession] close];
if(!error) {
NSLog(@"OG story posted, story ID: %@", [result objectForKey:@"id"]);
} else {
NSLog(@"Error: %@", error);
}
}];
} else {
NSLog(@"Error: %@", error);
}
}];
} else {
NSLog(@"Error: %@", error);
}
}];
}
我收到的错误信息：
