ios - 使用 native 应用程序登录 Facebook

Question

我需要通过自定义按钮登录 Facebook。
所以我做了以下方法。

- (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];
         }
     }];
}

之后我检查了真实设备(iPhone 5s(iOS 9.0))但它正在打开浏览器进行登录。
我已在我的设备中安装并登录了 facebook 应用程序。
虽然我面临这个问题。
请帮助我。

我注意到以下变更日志:

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.
