Fbsdkloginmanager Loginwithpublishpermissions Always Returns Iscancelled=Yes

FBSDKLoginManager logInWithPublishPermissions always returns isCancelled=YES

You should try adding in your AppDelegate didFinishLaunchingWithOptions :

return [[FBSDKApplicationDelegate sharedInstance] application:application
                                    didFinishLaunchingWithOptions:launchOptions];

This would get u [FBSDKAccessToken currentAccessToken] when user is logged in.

and

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {
    return [[FBSDKApplicationDelegate sharedInstance] application:application
                                                          openURL:url
                                                sourceApplication:sourceApplication
                                                       annotation:annotation];
}

If this method is not present into AppDelegate then it results into cancelled state.

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

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:

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

How to implement login with FB using FBSDKLoginManager?

Add following line in applicationDidFinishLaunching

return [[FBSDKApplicationDelegate sharedInstance] application:application
                                    didFinishLaunchingWithOptions:launchOptions];

and add this method in AppDelegate.m

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {
    return [[FBSDKApplicationDelegate sharedInstance] application:application
                                                          openURL:url
                                                sourceApplication:sourceApplication
                                                       annotation:annotation];
}

Facebook login fails (always isCancelled) after upgrading to SDK 4.1

Thanks to Dheeraj and its answer to a similar question, I found the error in my calls. I just made the stupidest error in Swift. In the unlikely event someone as dumb as I am read this, here are the 3 calls in Swift that you should add in your AppDelegate.swift. They are tested and working:

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

    // Do what you have to do but at the end, instead of 'return true', put :

    return FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
}

func application(application: UIApplication, openURL url: NSURL, sourceApplication: String?, annotation: AnyObject?) -> Bool {
    return FBSDKApplicationDelegate.sharedInstance().application(application, openURL: url, sourceApplication: sourceApplication, annotation: annotation)
}

func applicationDidBecomeActive(application: UIApplication) {
    FBSDKAppEvents.activateApp()
}

linkUserInBackground return succeeded as NO

I got my answer:
FBSDKLoginManager logInWithPublishPermissions always returns isCancelled=YES

"This can happen when your Facebook App doesn't have "publish_actions"
permission, or you're not using a test user."

ios Facebook Login button - doesn't change to Log out

so I started all over, and followed the instructions from the guide:

1.in the viewController.h file:

#import < FBSDKCoreKit/FBSDKCoreKit.h> //<-delete the space

#import < FBSDKLoginKit/FBSDKLoginKit.h>//<-delete the space

@interface ViewController : UIViewController<FBSDKLoginButtonDelegate>
@property (weak, nonatomic) IBOutlet FBSDKLoginButton *loginButton;

2.in the viewController.m file:

-(void) viewDidLoad{
   if ([FBSDKAccessToken currentAccessToken]) {
   // User is logged in, do work such as go to next view controller. 
   }

   self.loginButton.readPermissions = @[@"public_profile", @"email", @"user_friends"];

   FBSDKLoginButton *loginButton = [[FBSDKLoginButton alloc] init];
  [self.view addSubview:loginButton];
}

and after that didn't work, I've found this thread that mentioned I also need to add few things to the AppDelegate didFinishLaunchingWithOptions :

return [[FBSDKApplicationDelegate sharedInstance] application:application
                                didFinishLaunchingWithOptions:launchOptions];

and

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {
return [[FBSDKApplicationDelegate sharedInstance] application:application
                                                      openURL:url
                                            sourceApplication:sourceApplication
                                                   annotation:annotation];
}

and then it worked!
finally I had the Log in button changed to Log out!
