blocks|key|1104907|text|我遇到了一些问题，但我找到了解决办法。您可以将登录管理器的登录行为设置为使用电话上的Facebook详细信息。默认的行为是FBSDKLoginBehaviorSystemNative，它首先尝试使用Facebook应用程序，然后如果它不存在，则使用web模式。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1104908|您可以将登录行为设置为FBSDKLoginBehaviorSystemAccount.，而不是以这种方式传递似乎不起作用的urls。|offset|length|style|BOLD|1104909|长话短说，试着：|1104910|let+fbLoginManager+=+FBSDKLoginManager();

I had the some problem but I found a workaround. You can set the login behaviour of the Login Manager to use the Facebook details on the phone. The default behaviour is FBSDKLoginBehaviorSystemNative and that tries to use the Facebook app first and then if its not there, it uses a web modal.

Instead of doing it that way and passing around urls that don't seem to work you can set the login behaviour as FBSDKLoginBehaviorSystemAccount. 

Long story short, try:

<pre><code>let fbLoginManager = FBSDKLoginManager();
fbLoginManager.loginBehavior = FBSDKLoginBehaviorSystemAccount;
// call login method of choice here
</code></pre>

I got this issue too. It turned out that the app bundle id (in project configuration) mismatched with the app bundle id configured in the facebook app dashboard. After fixing the bundle id, the login worked just fine.

I had very similar problem while adding LoginButton in my app by following this tutorial → <a href="https://developers.facebook.com/docs/swift/login" rel="nofollow noreferrer">https://developers.facebook.com/docs/swift/login</a>.

After clicking the Facebook Connect button and finishing the authorization, it always returns with status 'cancelled'.
I tried many solutions and finally the following worked:

In AppDelegate.swift, add the following 2 functions:

<pre><code>func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -&gt; Bool {
 return SDKApplicationDelegate.shared.application(application, didFinishLaunchingWithOptions: launchOptions)
}

func application(_ application: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -&gt; Bool {
 return SDKApplicationDelegate.shared.application(application, open: url, options: options)

 return SDKApplicationDelegate.shared.application(application, didFinishLaunchingWithOptions: launchOptions)

<pre><code>@objc func loginButtonClicked() {
 let loginManager = LoginManager()
 loginManager.loginBehavior = .systemAccount
 loginManager.logIn([ .publicProfile,.userFriends,.email ], viewController: self) { loginResult in
 switch loginResult {
 case .failed(let error):
 print(error)
 case .cancelled:
 print("User cancelled login.")
 case .success(let grantedPermissions, let declinedPermissions, let accessToken):
 print("Logged in!")
 //Do further code...
 }
 }
}

it works for me in Swift 3.0 and SDK 4.17.0, I hope it works for you Thanks.

I found that the wrong AppDelegate method was being called. It was calling

<pre><code>func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -&gt; Bool {...
</code></pre>

instead of 

<pre><code>func application(_ application: UIApplication, open url: URL, sourceApplication: String?, annotation: Any) -&gt; Bool {...

So i had to add this to the first AppDelegate method (the one that was being called):

<pre><code>return FBSDKApplicationDelegate.sharedInstance().application(app, open: url, sourceApplication: "com.apple.mobilesafari", annotation: nil)
</code></pre>

Note that i had to pass the safari bundle ID explicitly, otherwise the FB account delegate would get <code>isCancelled = true</code>

blocks|key|57101|text|我的问题是由于我经常提出一个加载视图控制器，当视图消失时，我被解雇了。由于FBSDK在转换到Safari或应用程序时调用viewWillDisappear方法，所以它关闭了视图和FB登录屏幕。如果您在UIAlertController上显示登录，也会发生同样的事情。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|57102|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

My issue was caused from me modally presenting a loading view controller, which I had being dismissed when the view disappeared. Since FBSDK calls the viewWillDisappear method when transitioning to Safari or the app, it was closing the view and the FB login screen.

ORIGINAL:
I've been having the same problem and none of the other answers here worked for me. I went through the Facebook documentation carefully to make sure that I had everything correct, which I did. After some research, I discovered that this is a problem within the FBSDK itself starting with version 4.39.0. As it turned out, I had been using FBSDK version 4.40.0. The problem was completely resolved when I reverted to FBSDK version 4.38.0.

Solved for me : 

Delete Podfile.lock 
Delete Pods folder 
replace the facebook pods in your Podfile with this version of facebook 
pod 'FBSDKCoreKit', '~> 4.38.0' 
pod 'FBSDKLoginKit', '~> 4.38.0' 
now please notice that if you have FacebookShareKit or anything else for facebook you have to change it to the same version you are using which is 4.38.0

run your terminal with pod install 
open your project, go to Product > Clean Build Folder 
run the app and try.

worked for me, if it does for you let everybody knows.

cheers.

I'm currently trying implement Facebook login using the 4.0 version of the SDK, this also happens with the 3.+ version. When I call logInWithReadPermissions (4.0 version) or openActiveSessionWithReadPermissions (3.+ version). The closure/block is called immediately with isCancelled (4.0 version) and ClosedFailedLogin (3.+ version) before the user can make a selection (cancel or ok). I thought it may be a problem with the URL Scheme in my plist settings but I've checked it over and over and everything seems to be right. Just wondering if anyone may have any ideas on solving this problem. My Bundle ID is right, single signin is on, native app is enabled, in the Facebook dev console. See some sample code and configurations below (4.0 version).

Login Call:

AppDelegate:

Plist:

Facebook login always comes back as cancelled. (iOS Swift)
