Setting of facebook app for invite friend - ios

Question

It may be an easy question, but I am tired of it
Is there any setting for Facebook app (Which we set while creating an App in Facebook developer's site) for making "invite friend" functionality to be worked.
I am using WebDialog method as follows,
FBWebDialogs presentRequestsDialogModallyWithSession:nil
message:FacebookInviteMessage
title:#"Invite Friends"
parameters:parameters
handler:^(FBWebDialogResult result, NSURL *resultURL, NSError *error)
With the same method I am able to invite friend, when I am using the Facebook APP ID of another sample code in my project. But when I am using my own project's Facebook APP ID, invite is not working when I am getting Success in result url.
So I think there would be some setting in developer's site of Facebook.
Can anyone help for this
The complete code is
NSDictionary *parameters = self.fbidSelection ? #{#"to":self.fbidSelection} : nil;
MIDLog(#"self.fbidSelection %#",self.fbidSelection);
[FBWebDialogs presentRequestsDialogModallyWithSession:nil
message:FacebookInviteMessage
title:#"Invite Friends"
parameters:parameters
handler:^(FBWebDialogResult result, NSURL *resultURL, NSError *error) {
NSString *strResultUrl = [resultURL absoluteString];
if (result == FBWebDialogResultDialogCompleted && ![strResultUrl isEqualToString:#"fbconnect://success"])
{
MIDLog(#"Web dialog complete: %#", resultURL);
if (![resultURL query])
{
return;
}
NSDictionary *params = [self parseURLParams:[resultURL query]];
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);
UIAlertView *alrt = [[UIAlertView alloc] initWithTitle:#"Success!" message:#"Invitation(s) sent successfuly!" delegate:nil cancelButtonTitle:#"OK" otherButtonTitles: nil];
[alrt show];
alrt = nil;
}
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Success" message:FacebookInviteSuccess delegate:self cancelButtonTitle:#"Proceed" otherButtonTitles:nil];
alert.tag = 14114;
[alert show];
alert = nil;
// [self navigateToSearch];
}
else if (result == FBWebDialogResultDialogCompleted && [strResultUrl isEqualToString:#"fbconnect://success"])
{
MIDLog(#"Cancel Clicked");
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Cancelled" message:nil delegate:self cancelButtonTitle:#"Proceed" otherButtonTitles:nil];
alert.tag = 14114;
[alert show];
alert = nil;
}
else {
MIDLog(#"Web dialog not complete, error: %#", error.description);
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Error" message:InternetFailError delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil];
alert.tag = 15115;
[alert show];
alert = nil;
}
}
friendCache:self.friendCache];
}
Thank you
