Facebook setting for Invite friend in Facebook - ios

Question

It may be an easy question but can anybody tell me.
Is there any setting we need to do in the app (in Facebook developer site) for invite friends?
I have done all in code to invite friends.
When I substitute the Facebook APP ID of a sample code in which invite friend is working, then my code is also working fine.
But when I substitute my APP ID then the process is going fine, showing me successfully invitation message, but invitation is not sent.
I am using the following code:
[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;
}
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]
