Building Facebook IOS friend multi-selector - ios

Question

I want to build a friend multiselector so that my user can send a request to anyone of his friends. I know that there is the FBfriendselectorcontroller, but it does not have the option to select all friends, and I would like to have it in my app. I tried to populate a UITableview manually by getting the friend list in this way:
permissions (logged in using the log-in button):
NSArray *permissions = [[NSArray alloc] initWithObjects:#"public_profile", #"email", #"user_friends", nil];
self.loginView.readPermissions = permissions;
data:
[FBRequestConnection startWithGraphPath:#"me/friends"
parameters:nil
HTTPMethod:#"GET"
completionHandler:^(
FBRequestConnection *connection,
id result,
NSError *error
) {
//NSArray *data = [result objectForKey:#"data"];
NSLog(#"%#", result);
NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys: [NSString stringWithFormat:#"%#", result], #"to", #"send", #"action_type", #"YOUR_OBJECT_ID", #"object_id", nil];
[FBWebDialogs
presentRequestsDialogModallyWithSession:nil
message:#"Take this bomb to blast your way to victory!"
title:nil
parameters:params
handler:^(FBWebDialogResult result, NSURL *resultURL, NSError *error) {}
];
}];
the friend count returns 318, but the "data" is like this: (). I also tried the:
FBRequest* friendsRequest = [FBRequest requestForMyFriends];
[friendsRequest startWithCompletionHandler: ^(FBRequestConnection *connection,
NSDictionary* result,
NSError *error){
NSArray* friends = [result objectForKey:#"data"];
but the data is null. What am I doing wrong??!!
