I want to retrieve all my photo album from my Facebook account. I follow Graph API also and using latest Facebook API.
My code is like this:
-(IBAction)getgallery:(id)sender
{
FBRequest *request = [FBRequest requestForGraphPath:#"me/albums"];
[request startWithCompletionHandler:^(FBRequestConnection *connection, NSDictionary <FBGraphUser> *my, NSError *error) {
if ([my[#"data"]count]) {
for (FBGraphObject *obj in my[#"data"]) {
FBRequest *r = [FBRequest requestForGraphPath:[NSString stringWithFormat:#"/%#/photos", obj[#"id"]]];
[r startWithCompletionHandler:^(FBRequestConnection *c, NSDictionary <FBGraphUser> *m, NSError *err) {
//here you will get pictures for each album
}];
}
}
}];
}
I follow this link. But can't understanding properly. Please anyone can help me?
Nothing is happening when i press the getgallery button.

Seems like Facebook iOS SDK v4.0 has a lot of changes. I try to get a user's friends list after he login.
I think it's something to do with FBSDKGraphRequestConnection but I'm not sure how it can be used.
Also, if I only want to get friends who are using my app, does facebook sdk support that?
Can anyone give some examples? Thanks!
FBSDKGraphRequest *friendsRequest =
[[FBSDKGraphRequest alloc] initWithGraphPath:#"me/friends"
parameters:parameters];
FBSDKGraphRequestConnection *connection = [[FBSDKGraphRequestConnection alloc] init];
[connection addRequest:friendsRequest
completionHandler:^(FBSDKGraphRequestConnection *innerConnection, NSDictionary *result, NSError *error) {
...
}];
// start the actual request
[connection start];
This shows how to handle the response:
[[[FBSDKGraphRequest alloc] initWithGraphPath:#"me/friends" parameters:nil]
startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error)
{
if (!error)
{
NSArray * friendList = [result objectForKey:#"data"];
for (NSDictionary * friend in friendList)
{
NSLog(#"Friend id: %#", friend[#"id"]);
NSLog(#"Friend name: %#", friend[#"name"]);
}
}
}];
I used below code to get friend list
self.graphrequest = [[FBSDKGraphRequest alloc] initWithGraphPath:#"me/taggable_friends?limit=100"
parameters:#{ #"fields":#"id,name,picture.width(100).height(100)"}];
[self.graphrequest startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
if (!error) {
self.resultsArray = result[#"data"];
[self.fbTableView reloadData];
[self.fbTableView setHidden:NO];
} else {
NSLog(#"Picker loading error:%#",error.userInfo[FBSDKErrorLocalizedDescriptionKey]);
}
}];
You can limit the number of friends using limit keyword.Ex: limit=100
I have been working with the facebook sdk and parse and I am trying to retrieve a users facebook name but the documentation doesn't give me sufficient help and most tutorials on the net are out dated.
Can anyone tell how I can get a users name from the facebook sdk to display as a text label ? This would be greatly appreciated thanks.
You need to implement following FBLoginViewDelegate
- (void)loginViewFetchedUserInfo:(FBLoginView *)loginView user:(id<FBGraphUser>)user
{
NSLog(#"user is %# %#", [user objectForKey:#"email"], user.name);
}
You can retrieve it in this way:
FBRequest *request = [[FBRequest alloc] initWithSession:FBSession.activeSession graphPath:#"me"];
[request startWithCompletionHandler: ^(FBRequestConnection *connection,
NSDictionary < FBGraphUser > *my,
NSError *error)
{
NSString *username = my[#"username"];
}
I finally figured it out, you have to request the current users profile information than set your label with a "key" which in this case is called "name"
FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc] initWithGraphPath:#"me"
parameters:nil];
[request startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
NSLog(#"fetched user:%#", result);
_usernameText.text = result[#"name"];
}];
i am getting null in friends list this is my code
-(void)getFriendList
{
FBRequest *friendsRequest=[FBRequest requestForMyFriends];
[friendsRequest startWithCompletionHandler:^(FBRequestConnection *connection,NSDictionary* result,NSError *error)
{
arrFriendFB = [result objectForKey:#"data"];
arrFriendFB=[arrFriendFB valueForKey:#"first_name"];
NSLog(#"friemd=%#",arrFriendFB);
NSLog(#"friends description :%#",[arrFriendFB description]);
}];
}
As new facebook APi doc there is some modification. see some change's mention below
first you need to get access token with "user_friends" permission.
its graph API url:-
https://graph.facebook.com/me/friends?access_token=
For more information follow this link
https://developers.facebook.com/docs/facebook-login/permissions/v2.0
use this method to get friend list.
-(void)getFriendList
{
[FBSession setActiveSession:[self appDelegate].session];
FBRequest *friendRequest = [FBRequest requestForGraphPath:#"me/friends?fields=name,picture,location"];
[ friendRequest startWithCompletionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
NSArray *data = [result objectForKey:#"data"];
//NSLog(#"response : %#",data);
for (FBGraphObject<FBGraphUser> *friend in data)
{
NSLog(#"name : %#",[friend name]);
}
}];
}
I am trying to fetch work info for FB friends on iOS using Facebook SDK. Here's the code that I am using:
if (FBSession.activeSession.isOpen) {
NSMutableDictionary * params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
#"work", #"fields",
nil];
FBRequest *request = [FBRequest requestWithGraphPath:#"me/friends" parameters:params HTTPMethod:#"GET"];
[request startWithCompletionHandler:
^(FBRequestConnection *connection, NSDictionary *result, NSError *error) {
if (!error) {
if (result) {
if (result.count) {
NSMutableArray *friendsWithJobTitles = [NSMutableArray array];
for (id aFriend in [result objectForKey:#"data"]) {
if ([aFriend objectForKey:#"work"]) {
[friendsWithJobTitles addObject:aFriend];
}
}
NSLog(#"result = %#", friendsWithJobTitles);
}
}
}
}];
}
The friendsWithJobTitles is always blank for some reason. Please help.
I am running into issues trying upgrade my Facebook SDK to the latest production release (FacebookSDK-3.0.8.pkg - Facebook SDK 3.0 for iOS (update 1) [August 21, 2012]).
I am following along with tutorial on this page.
I have ran into several issues trying to get the code to work, it's not as easy as it proclaims to be in the tutorial. I can get my session open, but can not get the request to work.
- (IBAction)facebookTapped:(id)sender {
[FBSession openActiveSessionWithPermissions:nil allowLoginUI:YES completionHandler:^(FBSession *session, FBSessionState status, NSError *error) {
if(error) {
NSLog(#"Error opening session: %#", error);
return;
}
if(session.isOpen) {
NSLog(#"session is open");
FBRequest *me = [FBRequest requestForGraphPath:#"me"];
[me startWithCompletionHandler:^(FBRequestConnection *connection,
NSDictionary<FBGraphUser> *my,
NSError *error) {
NSLog(#"My name: %#", my.first_name);
}];
}
}];
}
My console displays that the session is open if I remove the call to FBRequest requestforGraphpath. If I leave it in, I receive the error "Incompatible block pointer types initializing 'void(^)(struct FBRequestConection , struct NSDictionary, struct NSError*)', expected 'FBRequestHandler'
Now what has me stumped is that this is the exact code shown in the tutorial, excpet that I changed out [FBRequest requestForMe] trying different approaches. None worked.
Can anyone shed some light on this for me?
Thank you.
I was able to solve this issue by changing their original block in the tutorial of:
if (session.isOpen) {
FBRequest *me = [FBRequest requestForMe];
[me startWithCompletionHandler: ^(FBRequestConnection *connection,
NSDictionary<FBGraphUser> *my,
NSError *error) {
self.label.text = my.first_name;
}];
}
to
if(session.isOpen) {
FBRequest *me = [FBRequest requestForMe];
[me startWithCompletionHandler:^(FBRequestConnection *connection,
id result,
NSError *error) {
NSDictionary<FBGraphUser> *my = (NSDictionary<FBGraphUser> *) result;
NSLog(#"My dictionary: %#", my.first_name);
}];
}
