Invite Facebook friends through iPhone App using FBWebDialogs - iphone

Question

I am using Facebook sdk 3.10 to send a request to multiple friend at a time using FBWebDialogs. Following code I'm using and all thing is fine like selecting multiple friends , sending them request. But there is one problem, is this FBWebDialogs uses some limit of friends as I have more that 300 friends but this is showing only 12-15 friends always.
CODE
[FBWebDialogs
presentRequestsDialogModallyWithSession:nil
message:#"Learn how to make your iOS apps social."
title:nil
parameters:nil
handler:^(FBWebDialogResult result, NSURL *resultURL, NSError *error) {
if (error) {
// Error launching the dialog or sending the request.
NSLog(#"Error sending request.");
} else {
if (result == FBWebDialogResultDialogNotCompleted) {
// User clicked the "x" icon
NSLog(#"User canceled request.");
} else {
// Handle the send request callback
NSDictionary *urlParams = [self parseURLParams:[resultURL query]];
if (![urlParams valueForKey:#"request"]) {
// User clicked the Cancel button
NSLog(#"User canceled request.");
} else {
// User clicked the Send button
NSString *requestID = [urlParams valueForKey:#"request"];
NSLog(#"Request ID: %#", requestID);
}
}
}
}];
Using above I can see only max 12 friends in the dialog? Am I missing something?
Any help would be appreciated.

You should pass the NSDictionary type object to parameters argument.
You can create like this:
NSArray *suggestedFriends = [[NSArray alloc] initWithObjects:#"fb_id1", #"fb_id2", nil];
NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:[suggestedFriends componentsJoinedByString:#","], #"suggestions", nil];
Now
[FBWebDialogs
presentRequestsDialogModallyWithSession:nil
message:#"Learn how to make your iOS apps social."
title:nil
parameters:params
handler:^(FBWebDialogResult result, NSURL *resultURL, NSError *error) {
if (error) {
// Error launching the dialog or sending the request.
NSLog(#"Error sending request.");
} else {
if (result == FBWebDialogResultDialogNotCompleted) {
// User clicked the "x" icon
NSLog(#"User canceled request.");
} else {
// Handle the send request callback
NSDictionary *urlParams = [self parseURLParams:[resultURL query]];
if (![urlParams valueForKey:#"request"]) {
// User clicked the Cancel button
NSLog(#"User canceled request.");
} else {
// User clicked the Send button
NSString *requestID = [urlParams valueForKey:#"request"];
NSLog(#"Request ID: %#", requestID);
}
}
}
}];
Here it will show all of the friends with the suggested Facebook ids.
