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,
   };

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

Latest Facebook SDK opens safari get reject in app store?

if you added more than these permission you need to submit for Facebook in your app, then Facebook takes the 7 -10 working days for check. if everything is fine you can upload your app in App Store else your app has rejected.

and Facebook submission process

if it is not the error for your app please ref this link

Facebook login through application through Facebook SDK in iOS?

We can check we have a Facebook application or not. But if you redirect the user to Facebook app, then there will not any login page in the FB app. Because Facebook .native for loginBehavior uses Safari to open user login.

In that Safari browser, you will have one option to open in the app. The user can either click on that and authorise in-app itself or just go by writing credentials on safari.

Update:

We can check Whether the user has installed a Facebook app or not with URI Scheme. But before that you have to register like this in your info.plist:

Open info.plist as a Source Code like this:

And paste below code.

LSApplicationQueriesSchemes

    fb

Now check like this:

BOOL isFBInstalled = [[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"fb://"]]

if (isFBInstalled) { //Check if FB app installed
//Do something
}

How to completely Logout of Facebook SDK Auth in iOS App

I was able solve my this issue by changing the FBSDKLoginBehavior to web, see here: https://stackoverflow.com/a/44101753/1258525

New facebook login redirect flow on iOS

You can try changing the loginBehavior of the login manager. See https://github.com/facebook/facebook-ios-sdk/blob/master/FBSDKLoginKit/FBSDKLoginKit/FBSDKLoginManager.h#L72. That alert is part of iOS 11' SFAuthenticationSession auth flow.

/**
  This is the default behavior, and indicates logging in through the native
 Facebook app may be used. The SDK may still use Safari instead.
 */
case native
/**
  Attempts log in through the Safari or SFSafariViewController, if available.
 */
case browser
/**
  Attempts log in through the Facebook account currently signed in through
 the device Settings.
 @note If the account is not available to the app (either not configured by user or
 as determined by the SDK) this behavior falls back to \c .native.
 */
case systemAccount
/**
  Attempts 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.

How to Open Social App Login within application using URL Scheme

Yes you are right, You need to customize URL Scheme handling little bit.

Here is example code

Basically You need to add Principle UIApplication class in .pList file as bellow Image and add notification center when you get URL login for your app ID.

and than, (Application.m)

- (BOOL)openURL:(NSURL*)url {
    if ([[url absoluteString] hasPrefix:@"https://m.facebook.com/v2.2/dialog/oauth?sdk_version="]) {
        [[NSNotificationCenter defaultCenter] postNotificationName:ApplicationAuthNotificationFB object:url];

        return NO;
    }
    return [super openURL:url];
}

and
Register Notification in your ViewController, (ViewController.m)

[[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(callLoginPopup:)
                                                 name:@"ApplicationAuthNotificationFB"
                                               object:nil];

Method to handle URL (ViewController.m)

-(void)callLoginPopup:(NSNotification *)notif{
    NSLog(@"URL To Handle ===> %@", [notif object]);
}

You can modify this example to achieve other social login within your app.

Facebook SDK login never calls back my application on iOS 9

Turns out that on iOS 9 when UIApplicationDelegate's application:openURL:options: is implemented, application:openURL:sourceApplication:annotation: will not get called.

So what I had to do is call FBSDKApplicationDelegate's application:openURL:sourceApplication:annotation: from UIApplicationDelegate's application:openURL:options:

- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary *)options {
    return [[FBSDKApplicationDelegate sharedInstance] application:app
                                                      openURL:url
                                            sourceApplication:options[UIApplicationOpenURLOptionsSourceApplicationKey]
                                                   annotation:options[UIApplicationOpenURLOptionsAnnotationKey]];
}
