Facebook API: Post on friend wall

I’m trying to post the message on a friends wall. But it doesn’t work with my below code,

 NSMutableDictionary* params = [NSMutableDictionary dictionary];
 [params setObject:@"Some text" forKey:@"user_message_prompt"];
 [params setObject:@"another text" forKey:@"action_links"];

 [facebook requestWithGraphPath:@"****FB ID here *****/feed" andParams:params andHttpMethod:@"POST" andDelegate:self];

I tried many ways to figure it out, but couldn’t find the solution. Please let me know what I did wrong in my code. I need a quick help to resolve.

This is how I push messages to a friends Facebook wall:

In your .h file:

#import "FBConnect.h"
#import "FBRequest.h"
#import "FBLoginButton.h"

....

Facebook* _facebook;
NSArray* _permissions;

...

@property (readonly) Facebook *facebook;

In your .m file:

@synthesize facebook = _facebook;

In viewDidLoad:

_permissions =  [[NSArray arrayWithObjects:@"user_photos",@"user_videos",@"publish_stream",@"offline_access",@"user_checkins",@"friends_checkins",@"email",@"user_location" , @"read_stream", @"read_friendlist",nil] retain];
_facebook = [[Facebook alloc] initWithAppId:kAppId];



SBJSON *jsonWriter = [[SBJSON new] autorelease];
static NSString* kAppId = @"your app key";

NSDictionary* actionLinks = [NSArray arrayWithObjects:[NSDictionary dictionaryWithObjectsAndKeys:@"your title",@"text",@"http://itunes.apple.com/us/app/facts!/id434894484?l=de&ls=1&mt=8",@"href", nil], nil];

NSString *actionLinksStr = [jsonWriter stringWithObject:actionLinks];
NSDictionary* attachment = [NSDictionary dictionaryWithObjectsAndKeys:
                                    @"Title of the post", @"name",
                                    @"Caption of the post", @"caption",
                                    @"Some description", @"description",
                                    nil];

NSString *attachmentStr = [jsonWriter stringWithObject:attachment];

NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                       kAppId, @"api_key",
                                       @"Share on Facebook",  @"user_message_prompt",
                                       actionLinksStr, @"action_links",
                                       attachmentStr, @"attachment",
                                       @"your friends id", @"to",
                                       nil];

[_facebook dialog: @"stream.publish" andParams:params andDelegate:self];

One thing has to be clear. You can only post to a friends wall when he is really in your friendlist, otherwise it will not work. I tested the code on my profile and it works!
