Facebook sdk crash in app deletion

Question

This is how I replicate the error. So here is the login code:

@IBAction func FBLoginAction(_ sender: AnyObject) { fbLoginManager.loginBehavior = FBSDKLoginBehavior.browser fbLoginManager.logIn(withReadPermissions: ["public_profile", "email", "user_friends"], from: self) { (result, error) -> Void in if (error != nil) { return } } } 

If I log in twice and run the application again, this line will fail in appdelegate.

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

If I register only once and run the application again, the crash will not happen. The complete stack for failure is as follows:

Answer 1

I returned to version 4.17.0 of the SDK for Facebook, and I no longer get a crash.

Answer 2

If you use version 4.18.0 from the SDK for Facebook, upgrade it to version 4.19.0 or the current version and you will not receive an error message.

Answer 3

Make sure you do not have limited versions of FBSDK in the Podfile , for example:

 pod 'FBSDKCoreKit' pod 'FBSDKLoginKit' pod 'FBSDKShareKit' 

Then do pod update . Do not put --no-repo-update to update local specifications.

The latest local spec stores allow you to download the latest version of FBSDK , which is 4.19.0 .
