Get Facebook Friends list and display it in custom view? - ios

Question

I'm trying to get FaceBook Friend list , and display it in custom view like "foresqure App"
what I mean "foursquare" ask for the permission and to post on your wall inside the app without leaving the app to the browser or to the app Facebook ? after that the app get all friends and display it in custom tableView.
here what I tried :
if (!FBSession.activeSession.isOpen) {
// if the session is closed, then we open it here, and establish a handler for state changes
[FBSession openActiveSessionWithReadPermissions:#[#"public_profile", #"user_friends"]
allowLoginUI:YES
completionHandler:^(FBSession *session,
FBSessionState state,
NSError *error) {
if (error) {
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:#"Error"
message:error.localizedDescription
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alertView show];
} else if (session.isOpen) {
//[self pickFriendsButtonClick:sender];
NSLog(#"aaaa");
FBRequest* friendsRequest = [FBRequest requestForMyFriends];
[friendsRequest startWithCompletionHandler: ^(FBRequestConnection *connection,
NSDictionary* result,
NSError *error) {
NSArray* friends = [result objectForKey:#"data"];
NSLog(#"Found: %i friends", friends.count);
for (NSDictionary<FBGraphUser>* friend in friends) {
NSLog(#"I have a friend named %# with id %#", friend.name, friend.id);
}
}];
}
}];
}
In this case it will open the safari to ask for permision not inside the app and friend array allows nill or count = 0.

Try this code ..
Firstly call this method like this ..
[self FBFriendList];
And add this two methods.
-(void)FBFriendList
{
if (!FBSession.activeSession.isOpen)
{
// if the session is closed, then we open it here, and establish a handler for state changes
[FBSession openActiveSessionWithReadPermissions:nil allowLoginUI:YES completionHandler:^(FBSession *session,FBSessionState state, NSError *error)
{
if (error)
{
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:#"Error" message:error.localizedDescription delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alertView show];
[alertView release];
}
else if(session.isOpen)
{
[self FBFriendList];
[self fb_frnd_use_this_app];
}
}];
return;
}
}
-(void)fb_frnd_use_this_app
{
FBRequest *request = [FBRequest requestWithGraphPath:#"me/friends"
parameters:#{#"fields":#"name,installed,first_name,picture"}
HTTPMethod:#"GET"];
[request startWithCompletionHandler:^(FBRequestConnection *connection,
id result,
NSError *error)
{
NSLog(#"%#",result);
int count = 0;
NSMutableArray *frnd_arr = [result objectForKey:#"data"];
for (int i = 0; i < [frnd_arr count]; i++)
{
NSLog(#"%#",frnd_arr);
count++;
}
NSLog(#"%#",app.Arr_Facebook_Frnd);
app.fbfriendCount =[NSString stringWithFormat:#"%d",count];
}];
}
Hope this code is useful for you.
