“Like” a Page using the Facebook Graph API, Objective C

Question

I'm trying to allow the user of my iOS app to "Like" a page using the following code:

NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:@"access_token",[[NSUserDefaults standardUserDefaults] objectForKey:@"fb_accessToken"], nil];

[facebook requestWithGraphPath:@"PAGE_ID/likes" andParams:params andHttpMethod:@"POST" andDelegate:self];

I get the error message:

Error Domain=facebookErrDomain Code=10000 "The operation couldn’t be completed. (facebookErrDomain error 10000.)" UserInfo=0x624d560 {error=<CFBasicHash 0x6243fb0 [0x171e400]>{type = mutable dict, count = 2,
        entries =>
            2 : <CFString 0x624cec0 [0x171e400]>{contents = "type"} = <CFString 0x624bc40 [0x171e400]>{contents = "OAuthException"}
            3 : <CFString 0x624aaf0 [0x171e400]>{contents = "message"} = <CFString 0x6248b50 [0x171e400]>{contents = "(#3) Application does not have the capability to make this API call."}
        }
        }

This should be part of the Graph API because it says you can use that to "Like" any object with a /Likes connections. Any help?

Answer 1

Sorry to be the bearer of bad news, but apparently You can't like a Page on behalf of a user. You can, however, like posts, comments, and photos on behalf of a user.

Hope this makes sense, I've spent the last few hours trying to do simular.

This appears to have recently changed, but now there is a new API - see https://developers.facebook.com/docs/opengraph/actions/builtin/likes/ for details.

Answer 3

https://developers.facebook.com/docs/reference/rest/stream.addLike/

and like a post

NSMutableDictionary* dict = [[[NSMutableDictionary alloc]initWithObjectsAndKeys:PostId,@"post_id",nil]autorelease];

[AppDelegate.facebook requestWithMethodName:@"stream.addLike" andParams:dict andHttpMethod:@"POST"  andDelegate:self];

and remove like

NSMutableDictionary* dict = [[[NSMutableDictionary alloc]initWithObjectsAndKeys:PostId,@"post_id",nil]autorelease];

[AppDelegate.facebook requestWithMethodName:@"stream.removeLike" andParams:dict andHttpMethod:@"POST"  andDelegate:self];`

Answer 4

The second paragraph of the page linked by Eric Kassan states that: "The og.likes action can refer to any open graph object or URL, except for Facebook Pages or Photos."

Answer 5

I have spent 10 hours for this solution.

But unfortunfortunitly there is not way.. even they have said "any object" in "likes" graph api but it's limited to only "users, it's posts, comments and photos".
