标签朋友在Facebook的照片上传 [英] Tag Friends in Facebook Photo Upload

问题描述

我想要使用图形标记api标记现有的朋友：

I'd like to be able to tag existing friends using the graph api:

这里是我现在的代码。照片正在上传，但照片未标记user_id中指定的用户：

Here's the code I have at the moment. The photo is being uploaded, but the photo isn't tagging the user specified in the user_id:

        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];

message_tags 属性不是正确的属性要使用？

Is the message_tags attribute not the correct attribute to use?

谢谢！

EDIT 请参阅这里（ https://developers.facebook.com/docs/reference/api/photo/#tags） ），看起来我需要总共发出三个电话：

EDIT From what I see here (https://developers.facebook.com/docs/reference/api/photo/#tags), it looks like I need to make three calls in total:

1. 使用我已经拥有的代码发布照片


2. 询问Facebook给我这张照片的ID（我可能从FBRequestDelegate获得）。

1. Post the Photo with the code I already have
2. Ask Facebook to give me the ID of this photo (which i can probably get from the FBRequestDelegate)
3. Tag People after posting.

推荐答案

首先，您要上传图片。

        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， - （void）请求： *）请求didLoad：（id）result 方法将返回一个字典 result with 1 key id 。该ID是您刚刚上传的照片的照片ID，并保存为字符串：

Next, upon successful upload, the - (void)request:(FBRequest *)request didLoad:(id)result method will return a dictionary result with 1 key id. That ID is the photoID of the photo you just uploaded, which you save into a string:

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

然后再创建一个GraphAPI请求来标记您的朋友。在下面的代码中，我标记了一个特定的朋友，但标记多个朋友使用CSV字符串或数组：

Then make another GraphAPI request to tag your friends. In the code below I am tagging one specific friends, but to tag multiple friends use CSV string or array:

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