Login with facebook with native app

Question

I need to facebook login via custom button.
So I made following method.

- (IBAction)loginWithFBClick:(UIButton *)sender
{
    FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];
    login.loginBehavior = FBSDKLoginBehaviorNative;

    [login
     logInWithReadPermissions: @[@"public_profile"]
     fromViewController:self
     handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) {
         if (error) {
             NSLog(@"Process error:%@",error);
         } else if (result.isCancelled) {
             NSLog(@"Cancelled");
         } else {
             NSLog(@"Logged in");
             HomeViewController *vc = [self.storyboard instantiateViewControllerWithIdentifier:@"HomeVC"];
             [self.navigationController pushViewController:vc animated:YES];
         }
     }];
}

After that I check in real device (iPhone 5s(iOS 9.0)) but It is opening browser for login.
I have installed and logged in facebook app in my device.
though I am facing this problem.
Please help me.

`login.loginBehavior = FBSDKLoginBehaviorNative;` comment this line and check and run — Rajan Maheshwari, Nov 25 '15 at 06:59
It is not opening a browser for login. It is displaying a webpage within your app. The simplest way to tell is that you don't get a prompt to switch apps (which is why FB changed the implementation for iOS 9). — Avi, Nov 25 '15 at 07:01
first that was the code.But faced this problem So, I added this line. — DeathStroke, Nov 25 '15 at 07:02
Which information? The behavior or the reason? The behavior is obvious; I already gave a simple way to verify it. The reason is speculation on my part, but if you can come up with a better reason, run with it. — Avi, Nov 25 '15 at 07:05

I noticed following changelogs:

Facebook SDK for iOS Changelog v4.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.

Following iOS 9 guide is just different that we need to add more key and values(array) of transport security and application query schemes. I also followed that – DeathStroke Nov 25 '15 at 07:51
you don't open native app becz..facebook depricate that thing...facebook replace sfsafariViewcontroller – Maulik shah Nov 25 '15 at 07:52
if you want to open native app then use old sdk. – Maulik shah Nov 25 '15 at 07:58
@Moseph what about iOS 8.x version using the same sdk(4.x)? – Rajan Maheshwari Nov 25 '15 at 08:16
