Post to Facebook Friend's Wall in iPhone using New Facebook SDK - iphone

Question

I want to post some texts and photo to one of my friend's wall using FBDialog.
I have a method like this
- (void)apiDialogFeedFriend:(NSString *)friendID :(NSString *)mImageSTR{
currentAPICall = kDialogFeedFriend;
FBSBJSON *jsonWriter = [FBSBJSON new];
NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
friendID, #"to",
#"I'm using the Hackbook for iOS app", #"name",
#"Hackbook for iOS.", #"caption",
#"Check out Hackbook for iOS to learn how you can make your iOS apps social using Facebook Platform.", #"description",
#"http://m.facebook.com/apps/hackbookios/", #"link",
#"http://www.facebookmobileweb.com/hackbook/img/facebook_icon_large.png", #"picture",
actionLinksStr, #"actions",
nil];
AppDelegate *delegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
[[delegate facebook] dialog:#"feed"
andParams:params
andDelegate:self];
}
Through these i get call back to dialogCompleteWithUrl method of FBDialogDelegate.
I have implemented this delegate method like this :
- (void)dialogCompleteWithUrl:(NSURL *)url {
if (![url query]) {
return;
}
NSDictionary *params = [self parseURLParams:[url query]];
switch (currentAPICall) {
case kDialogFeedUser:
case kDialogFeedFriend:
{
// Successful posts return a post_id
if ([params valueForKey:#"post_id"]) {
[self showMessage:#"Published feed successfully."];
NSLog(#"Feed post ID: %#", [params valueForKey:#"post_id"]);
}
break;
}
case kDialogRequestsSendToMany:
case kDialogRequestsSendToSelect:
case kDialogRequestsSendToTarget:
{
// Successful requests return the id of the request
// and ids of recipients.
NSMutableArray *recipientIDs = [[NSMutableArray alloc] init];
for (NSString *paramKey in params) {
if ([paramKey hasPrefix:#"to["]) {
[recipientIDs addObject:[params objectForKey:paramKey]];
}
}
if ([params objectForKey:#"request"]){
NSLog(#"Request ID: %#", [params objectForKey:#"request"]);
}
if ([recipientIDs count] > 0) {
[self showMessage:#"Sent request successfully."];
NSLog(#"Recipient ID(s): %#", recipientIDs);
}
break;
}
default:
break;
}
}
Here I get correct value of url as fbconnect://success?post_id=100001402819851_418640698226650.
Now, my problem is that in my friend wall my post is not seen/visible.
Any help would be appreciated.
