you should change handlefacebooksession part this:

- (void)handlefacebooksession { if ([pfuser currentuser]) {     if (self.delegate && [self.delegate respondstoselector:@selector(loginviewcontrollerdidloguserin:)]) {         [self.delegate performselector:@selector(loginviewcontrollerdidloguserin:) withobject:[pfuser currentuser]];     }     return; }  nsarray *permissionsarray = @[ @"public_profile",                                @"user_friends",                                @"email"];  self.hud = [mbprogresshud showhudaddedto:self.view animated:yes];  // login pfuser using facebook [pffacebookutils loginwithpermissions:permissionsarray block:^(pfuser *user, nserror *error) {      if (!user) {         nsstring *errormessage = nil;         if (!error) {             nslog(@"uh oh. user cancelled facebook login.");             errormessage = @"uh oh. user cancelled facebook login.";         } else {             nslog(@"uh oh. error occurred: %@", error);             errormessage = [error localizeddescription];         }         uialertview *alert = [[uialertview alloc] initwithtitle:@"log in error"                                                         message:errormessage                                                        delegate:nil                                               cancelbuttontitle:nil                                               otherbuttontitles:@"dismiss", nil];         [alert show];     } else {         if (user.isnew) {             nslog(@"user facebook signed , logged in!");         } else {             nslog(@"user facebook logged in!");         }          if (!error) {             [self.hud removefromsuperview];             if (self.delegate) {                 if ([self.delegate respondstoselector:@selector(loginviewcontrollerdidloguserin:)]) {                     [self.delegate performselector:@selector(loginviewcontrollerdidloguserin:) withobject:user];                 }             }         } else {             [self cancellogin:error];         }     } }];}
