How to fetch Facebook friends in ios 6? - iphone

Question

I want to send invite facebook friends from my app same as doing like in Instagram app.
But i can't find any good tutorial for that.
I able to get the name & id of the friend but I can't able to get the url for the profile image,name,etc. for the friends.
My code is as follow:
NSURL *requestURL = [NSURL URLWithString:#"https://graph.facebook.com/me/friends"];
SLRequest *request = [SLRequest requestForServiceType:SLServiceTypeFacebook
requestMethod:SLRequestMethodGET
URL:requestURL
parameters:nil];
request.account = self.facebookAccount;
[request performRequestWithHandler:^(NSData *data,
NSHTTPURLResponse *response,
NSError *error) {
if(!error)
{
list =[NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error];
NSLog(#"Dictionary contains data: %#", list );
if([list objectForKey:#"error"]!=nil)
{
[self attemptRenewCredentials];
}
dispatch_async(dispatch_get_main_queue(),^{
nameLabel.text = [list objectForKey:#"username"];
});
}
else{
//handle error gracefully
NSLog(#"error from get%#",error);
//attempt to revalidate credentials
}
}];
So, how can i achieve this?

This is code for it for fetching friends list
ACAccountStore *accountStore = [[ACAccountStore alloc] init];
__block ACAccount *facebookAccount = nil;
ACAccountType *facebookAccountType = [accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook];
// Specify App ID and permissions
NSDictionary *options = #{
ACFacebookAppIdKey: #"add_here_your_project_FB_ID",
ACFacebookPermissionsKey: #[#"publish_stream", #"publish_actions",#"read_friendlists"],
ACFacebookAudienceKey: ACFacebookAudienceFriends
};
[accountStore requestAccessToAccountsWithType:facebookAccountType
options:options completion:^(BOOL granted, NSError *error)
{
if (granted)
{
NSArray *accounts = [accountStore accountsWithAccountType:facebookAccountType];
facebookAccount = [accounts lastObject];
}
else {
NSLog(#"error.localizedDescription======= %#", error.localizedDescription);
}
}];
NSArray *accounts = [accountStore accountsWithAccountType:facebookAccountType];
facebookAccount = [accounts lastObject];
//NSString *acessToken = [NSString stringWithFormat:#"%#",facebookAccount.credential.oauthToken];
//NSDictionary *parameters = #{#"access_token": acessToken};
NSDictionary *param=[NSDictionary dictionaryWithObjectsAndKeys:#"picture,id,name,link,gender,last_name,first_name,username",#"fields", nil];
NSURL *feedURL = [NSURL URLWithString:#"https://graph.facebook.com/me/friends"];
SLRequest *feedRequest = [SLRequest
requestForServiceType:SLServiceTypeFacebook
requestMethod:SLRequestMethodGET
URL:feedURL
parameters:param];
feedRequest.account = facebookAccount;
[feedRequest performRequestWithHandler:^(NSData *responseData,
NSHTTPURLResponse *urlResponse, NSError *error)
{
if(!error)
{
id json =[NSJSONSerialization JSONObjectWithData:responseData options:kNilOptions error:&error];
NSLog(#"Dictionary contains data: %#", json );
if([json objectForKey:#"error"]!=nil)
{
//[self attemptRenewCredentials];
}
dispatch_async(dispatch_get_main_queue(),^{
//nameLabel.text = [json objectForKey:#"username"];
});
}
else{
//handle error gracefully
NSLog(#"error from get%#",error);
//attempt to revalidate credentials
}
}];
I hope it helps you. Thanks

you should include this in param
[ NSMutableDictionary dictionaryWithObjectsAndKeys:#"picture,id,name,link,gender,last_name,first_name",#"fields",nil]
