storyboard

• add uibutton , change class fbsdkloginbutton
• add segue uibutton next viewcontroller , name fbsegue
• add ibaction uibutton , call fbloginaction

loginviewcontroller.m

#import "loginviewcontroller.h" #import <parse/parse.h> #import <fbsdkcorekit/fbsdkcorekit.h> #import <fbsdkloginkit/fbsdkloginkit.h> #import <parsefacebookutilsv4/pffacebookutils.h>  - (ibaction)fbloginaction:(id)sender {         [self fblogin]; }  - (void)fblogin {     nsarray *permissions = @[@"public_profile", @"email"];     [pffacebookutils logininbackgroundwithreadpermissions:permissions block:^(pfuser *user, nserror *error) {         if (!user) {             nslog(@"uh oh. user cancelled facebook login.");         } else if (user.isnew) {             nslog(@"user signed , logged in through facebook!");             [self performseguewithidentifier:@"fbsegue" sender: self];         } else {             nslog(@"user logged in through facebook!");             [self performseguewithidentifier:@"fbsegue" sender: self];         }     }]; } 

problems

• when click login facebook button on ios simulator, safari page authorize app. when that, still see loginviewcontroller facebook button changed logout.

• when click logout button, taken facebook on safari message have authorized app , taken app. there option in bottom logout , cancel, in clicking either, taken next view controller.

any guidance please? understand since have not done under viewdidload method, user won't logged in , taken next view controller when app starts.

i think using fbsdkloginbutton in wrong way.

from documentation on https://developers.facebook.com/docs/reference/ios/current/class/fbsdkloginbutton/

fbsdkloginbutton works [fbsdkaccesstoken currentaccesstoken] determine display, , automatically starts authentication when tapped (i.e., not need manually subscribe action targets).

so shouldn't have use ibaction , can using uiview instead of uibutton fbsdkloginbutton
