How to integrate Facebook without redirect Safari browser in iOS app with latest FBSDK

yesterday I submit my app to store using FBSDKLoginManager using three kinds of Login with Facebook , actually Facebook follow the first three conditions automatically

Type -1

if the user already installed the Facebook native app the details will be retrieved from the app.

Type -2

if the user does't have the Facebook app, but he is logged in at the device's Settings, the user details will be taken from those.

Type -3

if none of the condition above is satisfied the user will be automatically redirected to Safari.

Type -4

    if you none of the above three conditions is relevant for you please continue below code.

apple does not reject your app

Objective-C

FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];
login.loginBehavior=FBSDKLoginBehaviorWeb;  // it open inside the app using popup menu

Swift

var fbLoginManager : FBSDKLoginManager = FBSDKLoginManager()
fbLoginManager.loginBehavior = FBSDKLoginBehavior.Native

FBSDKLoginBehavior Types

typedef NS_ENUM(NSUInteger, FBSDKLoginBehavior)
{
  /*!
@abstract Attempts log in through the native Facebook app. If the   Facebook app is
not installed on the device, falls back to \c  FBSDKLoginBehaviorBrowser. This is the
default behavior.
*/
 FBSDKLoginBehaviorNative = 0,
/*!
@abstract Attempts log in through the Safari browser
  */
FBSDKLoginBehaviorBrowser,
 /*!
  @abstract Attempts log in through the Facebook account currently signed in through Settings.
   If no Facebook account is signed in, falls back to \c FBSDKLoginBehaviorNative.
   */
 FBSDKLoginBehaviorSystemAccount,
  /*!
   @abstract Attemps log in through a modal \c UIWebView pop up

   @note This behavior is only available to certain types of apps. Please check the Facebook
   Platform Policy to verify your app meets the restrictions.
   */
  FBSDKLoginBehaviorWeb,
   };

the new concept

Facebook SDK for iOSv4.x

(v4.6.0 - September 10, 2015) In addition, the SDK dialogs such as Login, Like, Share Dialogs automatically determine the best UI based on the device, including SFSafariViewController instead of Safari. Follow the our Preparing for iOS 9 guide.

you can get like

When your select login behavior is FBSDKLoginBehaviorWeb, Then open webView popUp.

FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];
login.loginBehavior=FBSDKLoginBehaviorWeb;

PopUp Facebook :

Note : when facebook behavior is FBSDKLoginBehaviorBrowser then its always redirect on safari browser. Change its behavior to FBSDKLoginBehaviorWeb.

Use This For Latest Update from FB SDK

FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];
    login.loginBehavior = FBSDKLoginBehaviorWeb;
    NSArray *userdetails;
    [login logInWithReadPermissions:userdetails fromViewController:self handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) {
        if (error)
        {
            NSLog(@"Login Error : %@", error.description);
        }
        else if(result.isCancelled)
        {
            NSLog(@"Login Cancel By User");
        }
        else
        {
            //[self fetchUserDataForFacebookLogin];
            //[login logOut];
        }
    }];
