ios - The operation couldn’t be completed. (com.facebook.sdk error 2.) ios6 -


hi ussing ios6 facebook login , getting error native popup

the operation couldn’t completed. (com.facebook.sdk error 2.)

this scenario ive used. (i running on simularor)

i have logged in facebook app through settings , tried login app , working fine.

then logged out of facebook settings , logged in again different user. tried login app. getting error.

i tried loging out of app using command

[fbsession.activesession closeandcleartokeninformation];

but no use.

the bundle identifier in facebook app same in ios app.

this code used login

nsarray *permissions = [[nsarray alloc] initwithobjects:@"email", nil];     [fbsession openactivesessionwithreadpermissions:permissions                                        allowloginui:yes                                   completionhandler:      ^(fbsession *session,        fbsessionstate state, nserror *error) {          [self sessionstatechanged:session state:state error:error];      }];

any appreciated.

this error getting

domain=com.facebook.sdk code=2 "the operation couldn’t completed. (com.facebook.sdk error 2.)" userinfo=0x9535330 {com.facebook.sdk:errorloginfailedreason=com.facebook.sdk:systemlogindisallowedwithouterror, com.facebook.sdk:errorsessionkey=, expirationdate: (null), refreshdate: (null), attemptedrefreshdate: 0001-12-30 00:00:00 +0000, permissions:(null)>}

note got same error on different occation. @ time bug in code

instead of giving permission

nsarray *permissions = [[nsarray alloc] initwithobjects:@"email",@"birthday", nil];

i wrongly doing

nsarray *permissions = [[nsarray alloc] initwithobjects:@"email,birthday", nil];

solution after correcting code, getting same error. have logout , login facebook ios settings screen. once did correct code never caused problem. note problem occured on device executed buggy code. note sure caused problem, hope info helps

this worked me:

  • go settings app of iphone.
  • open facebook settings
  • scroll down app , make sure app allows facebook interaction.

this happen on device, therefore in app have make sure handle error correctly. reckon give user feedback why login facebook failed , ask user check facebook settings on device.
