After being able to create a small iOS app that logs in to Facebook. I would like this app to get the user’s list of friends.
Though I browsed the internet for a while and tried various approach I did not succeed to get what I wanted.
In the viewDidLoad method I use this code to start with:
loginView = [[FBLoginView alloc] initWithReadPermissions:#[#"user_friends"]];
And then I implement the loginViewFetchedUserInfo: user: method this way:
- (void)loginViewFetchedUserInfo:(FBLoginView *)loginView
user:(id<FBGraphUser>)user
{
[FBRequestConnection startWithGraphPath:#"/me/friends"
parameters:nil
HTTPMethod:#"GET"
completionHandler:^(
FBRequestConnection *connection,
id result,
NSError *error
) {
NSLog(#“Result: %#",result);
}];
}
When I execute the app I get this result:
Result: {
data = (
);
summary = {
"total_count" = 267;
}; }
But what I really want is a list of the friends with their names …etc…
All the things I tried for that didn’t work. Though I suppose the solution must be simple.
I also used code like this in the method above ….. but with no luck:
NSArray* friends = [result objectForKey:#"data"];
One more point, here https://developers.facebook.com/docs/graph-api/reference/v2.1/user/friends one can read:
This will only return any friends who have used (via Facebook Login)
the app making the request.
But the result I get (267) does not match this statement. It (267) is the number of friends the user has on Facebook, which is in fact what I am interested in.
I hope someone has something to say to put me on the right track and make things clearer.
Since Facebook's 2.x SDK upgrade they have tightened up access to information in the "Open Graph API."
Under Permissions That Do Not Require Review
App friends. This optional permission grants your app the ability to read a list of friends who also use your app.
You get automatic access to any friends that already use your app (per its Facebook ID.)
You will have to request Extended Permissions if you want to access the list of all a user's friends. That means going through Facebook's App Review process which can be quite challenging (and annoying.)
Frankly, I am not even sure that it is possible to use the new Open Graph API to get the user's entire friend list.
Ok so there is a lot of threads on this, but nothing seems to work for me.
My app allows users to post a photo (which is a UIImage created by a screenshot of the App) to facebook.
However, I can currently only post the photo by using:
NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:[[appDelegate facebook] accessToken], #"access_token",nil];
[params setObject:#"Caption" forKey:#"name"];
[params setObject:[self captureScreen] forKey:#"source"];
if([[appDelegate facebook] requestWithGraphPath:#"me/photos" andParams: params andHttpMethod: #"POST" andDelegate:(id)self]){
[self.view addSubview:[Memos showMemo:facebookMemo]];//Show success alert
}
This works fine, but doesn't use any sort of FB Dialog.
I really want to use the dialog so users can feel like it is more "facebook official" and allow them to preview/confirm the post.
Is there any SIMPLE way to go about doing this?
This is the closest I have gotten: Post photo on user's wall using Facebook iOS SDK, but I have issues with these lines:
currentAPICall = kAPIGraphUserPhotosPost;
As xcode doesnt recognize any of the kAPI... objects...
Suggestions?
Our iOS app required the 'publish_stream' permission. We're now removing it and passing in an empty string NSArray but it doesn't reflect in the auth screen.
It keeps telling the user "This app may post on your behalf, including status updates, photos and more." and we can't seem to reset that.
- (void)facebookLogin
{
NSArray *permissions = [NSArray arrayWithObjects: #"",nil]; // was #"publish_stream"
// Look here for a list of available permissions:
// http://developers.facebook.com/docs/reference/api/permissions/
[_facebook authorize:permissions];
}
We tried passing in nil instead of the empty string NSArray but that didn't help.
Are there auth options to be adjusted in the App Settings of the developers page?
Any ideas?
Thanks!

This is apparently a recent bug. See the developer forums here. Hopefully they'll be resolving it soon.
As soon as the user is logged in, I retrieve the user info using this code:
[_facebook requestWithGraphPath:#"me" andDelegate:self];
It worked for the first few times, but it eventually returned an error. I thought it was a session thing since I have "offline_access" on my permissions. I logged out from Facebook and compiled again from a clean build and it still returns this error:
Error Domain=facebookErrDomain Code=10000 UserInfo=0x54a2930 "Operation could not be completed. (facebookErrDomain error 10000.)"
I'm assuming my access token is valid since I can do posting. Am I right to assume that?
I also noticed that whenever I log in, Facebook doesn't redirect me to ask permission if I allow my app to access my user info.
Can anyone tell me what's wrong?
Answer on authorize command seems to be different. Now, there's no expiration date as it was before. I tried with forcing isSessionValid to return TRUE, and it works.
isSessionValid checks accessToken AND expirationDate. As there's no expiration date, the function return FALSE.
Don't know if it's a temporary modification from facebook, or definitive one. In this case, SDK must be fixed, I presume. And a new call must retrieve expirationDate.
Here's a temporary fix I've used. You can find this method line 46 in FBLoginDialog.m
- (void) dialogDidSucceed:(NSURL*)url {
NSString *q = [url absoluteString];
NSString *token = [self getStringFromUrl:q needle:#"access_token="];
NSDate *expirationDate = [NSDate distantFuture];
if ((token == (NSString *) [NSNull null]) || (token.length ==0)) {
[self dialogDidCancel:url];
[self dismissWithSuccess:NO animated:YES];
} else {
if ([_loginDelegate respondsToSelector:#selector(fbDialogLogin:expirationDate:)]) {
[_loginDelegate fbDialogLogin:token expirationDate:expirationDate];
}
[self dismissWithSuccess:YES animated:YES];
}
}
Does everyone with this issue request the offline_access permission? It's the only reason I can see an expiration date not being sent. Maybe try not requestion the offline_access permission.
I've had same problem. I checked my privacy settings,permissions,other method etc..., but I couldn't solve it.
Many sites said "check permission for accessing to offline_access/read_stream/publish_stream",I think these are important too,but I couldn't fix it.
Then I found following solution finally, it works fine.
You should change "safariAuth:YES" to "safariAuth:NO" on "Facebook.m" file.
- (void)authorize:(NSArray *)permissions
delegate:(id<FBSessionDelegate>)delegate {
[_permissions release];
_permissions = [permissions retain];
_sessionDelegate = delegate;
//[self authorizeWithFBAppAuth:YES safariAuth:YES];
//You can get auth_token in iOS App!
[self authorizeWithFBAppAuth:YES safariAuth:NO];
}
Then you can use following method to get your own info if you are logged in.
[facebook requestWithGraphPath:#"me" andDelegate:self];
if you are not logged in, You should login by following method first.
permissions = [[NSArray arrayWithObjects:
#"email", #"read_stream", #"user_birthday",
#"user_about_me", #"publish_stream", #"offline_access", nil] retain];
if (![facebook isSessionValid]) {
[facebook authorize:permissions delegate:self];
}
Following post saved me.Thank you so much!
How to retrieve Facebook response using Facebook iOS SDK
Good Luck & Happy-coding!
Thank you.
I've had this problem, mainly because my Facebook account has is maxed on privacy.
It's most likely the permissions that you passed in during login. BY default it will only give access to public info. Remember there is less and less info that is public in Facebook.
Try changing your permission to something like "read_stream",nil
Then instead of [_facebook requestWithGraphPath:#"me" andDelegate:self];
Try using [_facebook requestWithGraphPath:#"me/home" andDelegate:self];
This should return your news feed.
Worked for me 5 mins ago.
Not much to add here, doesn't work here too. I use the iOS SDK to post to the stream and it worked until yesterday. Today my client called me and complained. Ugh.
I have requested the offline access permission and of course the "publish_stream" permission...
How to add news via FBConnect?
I have the following code:
NSString *newsBody = #"[{\"message\": \"News message\" }]";
NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObject:newsBody forKey:#"news"];
[[FBRequest requestWithDelegate:self] call:#"facebook.dashboard.addnews" params:params dataParam:nil];
After I sent the request I received the success responce. But I can't see the new news in the facebook account.
Also, I tried to add full info into news parameter (http://wiki.developers.facebook.com/index.php/Dashboard.addNews):
NSString *newsBody = #"[{\"message\": \"News message\",\"action_link\": {\"text\": \"link text\",
\"href\": \"http: //google.com\"} }]";
But this request returns error.
Any ideas?
I found the answer. The FBStreamDialog should be used to publish the news. It means that the custom interface cannot be used for this purposes. :(
Also, just wanted to say that FBConnect it's a one big mess!! Currently fighting with the bug when after clicking Cancel button in the FB dialog the dialog firing the event dialogDidSucceed but not dialogDidCancel. Such a big mess!!!
