I am trying to get all the events that user has created for that i am trying to request permission for accessing the user_events.
However thus far facebook is not asking user for permission to access events. I have checked the test user app permission profile and my app is only getting profile info but not events settings.
The facebook sdk i am using is 3.19
if ([FBSession.activeSession.permissions indexOfObject:#"user_events"]==NSNotFound) {
[FBSession.activeSession requestNewReadPermissions:#[#"user_events"] completionHandler:^(FBSession *session, NSError *error) {
if (!error) {
action();
}
else if (error.fberrorCategory != FBErrorCategoryUserCancelled)
{
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:#"Permission denied"
message:#"Unable to get permission to post"
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alertView show];
}
}];
}
else
{
action();
}
user_events needs to get approved by Facebook before it works with any user, else it will only work for users with a role in your app: https://developers.facebook.com/docs/apps/review/login

Using Parse (iOS framework), I am able to sign up and login successfully using two API.
When user log in, it will cache the user and so accessing "currentUser" will return appropriate object. But sign up API is not caching.
Is there any way that sign up itself will cache the user and avoid separate log in functionality?
It should automatically log you in as well. For example, if in your completion block in signUpInBackground, you have a segue to your main screen and in your main screen, it is supposed to show information related to the user, then it will because [PFUser currentUser] is set to the user that registered.
here is an example
[user signUpInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {
if (error) {
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:[[error userInfo] objectForKey:#"error"] message:nil delegate:self cancelButtonTitle:nil otherButtonTitles:#"Ok", nil];
[alertView show];
// Bring the keyboard back up, because they'll probably need to change something.
[_usernameField becomeFirstResponder];
}
else{
// Success!
[self performSegueWithIdentifier:#"goToMain" sender:self];
}
}];
i am unable to post to Facebook using Facebook ios sdk. i am receiving the following error.
"This app does not have permission to do this. to change permissions to do this. To change permissions, try logging into the app again."
- (void) performPublishAction:(void (^)(void)) action {
// we defer request for permission to post to the moment of post, then we check for the permission
if ([FBSession.activeSession.permissions indexOfObject:#"publish_actions"] == NSNotFound) {
// if we don't already have the permission, then we request it now
[FBSession.activeSession requestNewPublishPermissions:#[#"publish_actions"]
defaultAudience:FBSessionDefaultAudienceFriends
completionHandler:^(FBSession *session, NSError *error) {
if (!error) {
action();
} else if (error.fberrorCategory != FBErrorCategoryUserCancelled){
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:#"Permission denied"
message:#"Unable to get permission to post"
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alertView show];
}
}];
} else {
action();
}
}
i am using Facebook ios sample from git-hub for testing.i can successfully post to Facebook if i use some old app create on Facebook.i have created the app as described by the Facebook docs.
read the facebook document v2.0 carefully, i do have similar problem.
If your app asks for more than public_profile, email and user_friends, then it will have to be reviewed by Facebook before it can be made available to the general public. Please see our documentation on reviews for more information.
You have to register your app to Facebook at https://developers.facebook.com. Make sure to enter your app's bundle id exactly as it is in Xcode.
I am trying to login to a facebook account without the admin and test user I have been testing with. This is using the Parse.com framework facebook login utility. I get the error:
NSLocalizedDescription=User is not a test user owned by the application
My code to authenticate with facebook is hitting this condition:
[PFFacebookUtils logInWithPermissions:nil block:^(PFUser *user, NSError *error) {
if (!user) {
NSLog(#"User doesn't exist");
NSLog(#"%#", error);
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:#"Error"
message:error.localizedDescription
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alertView show];
}
I have set my app to: "Live and Available to All Users" in the facebook developer app dashboard.
Why am I receiving this error and how do I allow my app to be logged in by any user with a facebook account?
The problem was that I was already logged in in the simulator with a non valid account.
Recently I was assigned to survey how to use iOS framework ACAccount and Social to implement facebook post function. It is quite simple to gain access of the account configured in setting.
if(!_accountStore)
_accountStore = [[ACAccountStore alloc] init];
ACAccountType *facebookTypeAccount = [_accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook];
// Check if there is any faceboook account
NSArray *accounts = [_accountStore accountsWithAccountType:facebookTypeAccount];
if (![accounts count]) {
UIAlertView *alert = [[UIAlertView alloc]initWithTitle:#"alert" message:#"No facebook account configured in setting." delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alert show];
return;
}
[_accountStore requestAccessToAccountsWithType:facebookTypeAccount
options:#{ACFacebookAppIdKey: #"FACEBOOK-APP-ID", ACFacebookPermissionsKey: #[#"email"]}
completion:^(BOOL granted, NSError *error) {
if(granted){
NSArray *accounts = [_accountStore accountsWithAccountType:facebookTypeAccount];
_facebookAccount = [accounts lastObject];
NSLog(#"Success");
}else{
// ouch
NSLog(#"Failed, Error: %#", error);
dispatch_async(dispatch_get_main_queue(), ^{
NSString *message = [NSString stringWithFormat:#"App access denied, please grant access in Setting->Facebook. Error message:：%#", error];
UIAlertView *alert = [[UIAlertView alloc]initWithTitle:#"Alert" message:message delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alert show];
});
}
}];
Once the app gain access to facebook, it can post message by using SLComposeViewController:
- (IBAction)postButtonPressed:(id)sender {
if (!_facebookAccount) {
UIAlertView *alert = [[UIAlertView alloc]initWithTitle:#"alert" message:#"login first" delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alert show];
return;
}
SLComposeViewController *fbController = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];
if([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook]) {
SLComposeViewControllerCompletionHandler __block completionHandler=^(SLComposeViewControllerResult result){
[fbController dismissViewControllerAnimated:YES completion:nil];
switch(result){
case SLComposeViewControllerResultCancelled:
default:
{
NSLog(#"Cancelled.....");
}
break;
case SLComposeViewControllerResultDone:
{
NSLog(#"Posted....");
}
break;
}};
[fbController setInitialText:#"Test message"];
[fbController setCompletionHandler:completionHandler];
[self presentViewController:fbController animated:YES completion:nil];
} else {
NSLog(#"no facebook setup");
}
Here comes my question. I found that there is a method in ACAccountStore which is used to renew expired credential of an ACAccount:
- (void)renewCredentialsForAccount:(ACAccount *)account completion:(ACAccountStoreCredentialRenewalHandler)completionHandler;
But I don't even know how to check whether the credential is expired so that I can renew it. Anyone got an idea about this?
Oh, by the way, we just want to use the native Social framework to do simple work such as post some message or picture. So, if not needed, we are not going to use the facebook SDK.
If you know anything about how to check the credential is valid or not, please leave a comment or submit an answer, thank you:)

I learn something from my experiments to this issue..
One is not able to get certain type of accounts from account store before he gains access to them, so I should not check account count before request for access.
Renew notification called when the app using ACAccount is in background after facebook account changed. Currently, I only saw changes of access right triggers the notification.
If the user changes password, the system will pop out an alert when the user attempt to post something, which ask the user to change password.
I think monitor notifications of account change is enough to handle the changes. I'll accept the first answer.
You should renew the user acc everytime it is out of sync. This may happen if the user has changed his password or when the acc session has expired.
Yo can know you are in that scenario using the following notification:
ACAccountStoreDidChangeNotification
I don't think there is active way , best is to write renew function and call
renewCredentialsForAccount of the framework
I want to post text and link from iOS app to user timeline. I copy and paste FBWebDialogs example.
Problem 1:
The post appear in my timeline but the permission is "Only me", not friend or public.
Problem 2:
The result object (FBWebDialogResult) is nil. Log appear in my console.NSLog(#"User canceled story publishing.");
Problem 3:
The permission of preview box is "only me" even I set it to public
Attached setting of my Facebook page:
Here is my code:
[FBWebDialogs presentFeedDialogModallyWithSession:nil
parameters:params
handler:
^(FBWebDialogResult result, NSURL *resultURL, NSError *error) {
if (error) {
// Error launching the dialog or publishing a story.
NSLog(#"Error publishing story.");
} else {
if (result == FBWebDialogResultDialogNotCompleted) {
// User clicked the "x" icon
NSLog(#"User canceled story publishing.");
} else {
// Handle the publish feed callback
NSDictionary *urlParams = [self parseURLParams:[resultURL query]];
if (![urlParams valueForKey:#"post_id"]) {
NSLog(#"User canceled story publishing.");
} else {
NSString *msg = [NSString stringWithFormat:
#"Posted story, id: %#",
[urlParams valueForKey:#"post_id"]];
[[[UIAlertView alloc] initWithTitle:#"Result"
message:msg
delegate:nil
cancelButtonTitle:#"OK!"
otherButtonTitles:nil]
show];
}
}
}
}];
The setting page of my app is "only me" by default. I don't expect all my users change this setting here.
OMG. I stuggled for whole day but no progress. I found solution as soon as I ask question.
The problem is I copied inappropriate sample code. Ichanged to [FBSession openActiveSessionWithPublishPermissions] and problem solved.
Here is the login code I used. My post can be public now.
- (void)buttonRequestClickHandler:(id)sender {
// FBSample logic
// Check to see whether we have already opened a session.
if (FBSession.activeSession.isOpen) {
// login is integrated with the send button -- so if open, we send
// [self sendRequests];
NSLog(#"Login in facebook");
} else {
NSArray *permission = [NSArray arrayWithObjects:#"publish_actions", nil];
[FBSession openActiveSessionWithPublishPermissions:permission defaultAudience:FBSessionDefaultAudienceEveryone allowLoginUI:YES completionHandler:^(FBSession *session,
FBSessionState status,
NSError *error) {
// if login fails for any reason, we alert
if (error) {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Error"
message:error.localizedDescription
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alert show];
// if otherwise we check to see if the session is open, an alternative to
// to the FB_ISSESSIONOPENWITHSTATE helper-macro would be to check the isOpen
// property of the session object; the macros are useful, however, for more
// detailed state checking for FBSession objects
} else if (FB_ISSESSIONOPENWITHSTATE(status)) {
// send our requests if we successfully logged in
NSLog(#"Login in facebook"); }
}];
}
