在Facebook Photo Upload上标记朋友

Question

我希望能够使用图形api标记现有的朋友:

这是我目前的代码.照片正在上传,但照片未标记user_id中指定的用户:

        UIImage *testImage = [UIImage imageNamed:@"sendingTo"];
        NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:kFacebookFBConnectAppID, @"app_id",
                                       testImage, @"source",
                                       @"1381470076", @"message_tags",
                                       @"TEST!", @"message", nil];


        [self.socialIntegration.facebook requestWithGraphPath:[NSString stringWithFormat:@"/me/photos?access_token=%@", self.socialIntegration.facebook.accessToken]
                                                    andParams:params 
                                                andHttpMethod:@"POST" andDelegate:self];

是message_tags属性不使用正确的属性？

谢谢!

编辑 从我在这里看到的(https://developers.facebook.com/docs/reference/api/photo/#tags),看起来我需要总共进行三次调用:

1. 使用我已有的代码发布照片
2. 让Facebook给我这张照片的ID(我可以从FBRequestDelegate获得)
3. 发布后标记人物.

好吧,想通了.

这是你如何做到的.

首先,您上传图像.

        UIImage *testImage = [UIImage imageNamed:@"sendingTo"];
        NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:kFacebookFBConnectAppID, @"app_id",
                                       testImage, @"source",
                                       @"TEST!", @"message", nil];


        [self.socialIntegration.facebook requestWithGraphPath:[NSString stringWithFormat:@"/me/photos?access_token=%@", self.socialIntegration.facebook.accessToken]
                                                    andParams:params 
                                                andHttpMethod:@"POST" andDelegate:self];

接下来,成功上传后,该- (void)request:(FBRequest *)request didLoad:(id)result方法将返回result带有1个键的字典id.该ID是您刚上传的照片的photoID,您将其保存为字符串:

NSString *photoID = [NSString stringWithFormat:@"%@", [(NSDictionary*)result valueForKey:@"id"]];

然后再制作另一个GraphAPI请求以标记您的朋友.在下面的代码中,我正在标记一个特定的朋友,但要标记多个朋友使用CSV字符串或数组:

[self.socialIntegration.facebook requestWithGraphPath:[NSString stringWithFormat:@"%@/tags/%@?access_token=%@", photoID, @"1381470076", self.socialIntegration.facebook.accessToken]
                                                    andParams:nil 
                                                andHttpMethod:@"POST" andDelegate:self];
