Facebook wall post error : OAuthException

Question

I integrated facebook login in my code successfully. Now want to POST on a wall.

Below is the error:

FBRequest didFailWithError:The operation couldn’t be completed. (facebookErrDomain error 10000.) Error Domain=facebookErrDomain Code=10000 "The operation couldn’t be completed. (facebookErrDomain error 10000.)" UserInfo=0xeaf9870 {error=<CFBasicHash 0xeaf9770 [0x20eb400]>{type = mutable dict, count = 3,
entries =>
    2 : <CFString 0xead54f0 [0x20eb400]>{contents = "type"} = <CFString 0xead6470 [0x20eb400]>{contents = "OAuthException"}
    3 : <CFString 0xead4610 [0x20eb400]>{contents = "message"} = <CFString 0xead4660 [0x20eb400]>{contents = "(#200) This API call requires a valid app_id."}
    6 : <CFString 0xead4180 [0x20eb400]>{contents = "code"} = 200
}
}

//CODE

[_facebook requestWithGraphPath:[NSString stringWithFormat:@"/%@/feed",[defaults objectForKey:@"FBUDID"]] 
                          andParams:variables 
                      andHttpMethod:@"POST" 
                        andDelegate:self];

I have checked AppID & secret key.

Please help. Thanks

Answer 1

NSMutableDictionary *params = [[[NSMutableDictionary alloc] init] autorelease];
[params setObject:@"status" forKey:@"type"];
[params setObject:@"Write your message here to post" forKey:@"message"];
[_facebook requestWithGraphPath:@"me/feed" andParams:params andHttpMethod:@"POST" andDelegate:self];

Posting message to self (User who is logged in) wall can be done using above code. let me know in case of any query.
