Всегда возвращать ошибку FBErrorCategoryUserCancelled при входе через Facebook в моем приложении
В моем приложении есть три способа входа в систему. одним из них является логин через фейсбук. Но когда я нажимаю на кнопку Facebook, он спрашивает у меня разрешения доступа, когда нажимаюOK тогда это возвращаетсяFBErrorCategoryUserCancelled, И это происходит не на всех устройствах, а на некоторых устройствах. Вот мой код -
if ([[FBSession activeSession]isOpen]) {
/*
* if the current session has no publish permission we need to reauthorize
*/
if ([[[FBSession activeSession]permissions]indexOfObject:@"publish_actions"] == NSNotFound) {
[[FBSession activeSession] requestNewPublishPermissions:[NSArray arrayWithObject:@"publish_actions"] defaultAudience:FBSessionDefaultAudienceFriends
completionHandler:^(FBSession *session,NSError *error){
[ProgressHUD dismiss];
self.view.userInteractionEnabled = YES;
}];
}else{
[self fetchUserDetails];
}
}else{
/*
* open a new session with publish permission
*/
[FBSession openActiveSessionWithPublishPermissions:[NSArray arrayWithObject:@"publish_actions"]
defaultAudience:FBSessionDefaultAudienceOnlyMe
allowLoginUI:YES
completionHandler:^(FBSession *session, FBSessionState status, NSError *error) {
if (!error && status == FBSessionStateOpen) {
[self fetchUserDetails];
}else{
NSLog(@"error");
if ([FBErrorUtility shouldNotifyUserForError:error]) {
alertTitle = @"Facebook Error";
alertMessage = [FBErrorUtility userMessageForError:error];
// This code will handle session closures that happen outside of the app
// You can take a look at our error handling guide to know more about it
// https://developers.facebook.com/docs/ios/errors
} else if ([FBErrorUtility errorCategoryForError:error] == FBErrorCategoryAuthenticationReopenSession) {
alertTitle = @"Session Error";
alertMessage = @"Your current session is no longer valid. Please log in again.";
// If the user has cancelled a login, we will do nothing.
// You can also choose to show the user a message if cancelling login will result in
// the user not being able to complete a task they had initiated in your app
// (like accessing FB-stored information or posting to Facebook)
} else if ([FBErrorUtility errorCategoryForError:error] == FBErrorCategoryUserCancelled) {
NSLog(@"user cancelled login");
alertTitle = @"Facebook Error";
alertMessage = @"System login cancelled";
// For simplicity, this sample handles other errors with a generic message
// You can checkout our error handling guide for more detailed information
// https://developers.facebook.com/docs/ios/errors
} else {
alertTitle = @"Something went wrong";
alertMessage = @"Please try again later.";
NSLog(@"Unexpected error:%@", error);
}
[[[UIAlertView alloc] initWithTitle:alertTitle
message:alertMessage
delegate:nil
cancelButtonTitle:@"OK"
otherButtonTitles:nil] show];
[ProgressHUD dismiss];
self.view.userInteractionEnabled = YES;
}
}];
}
Любая помощь будет оценена. Спасибо.
