Question

这是我如何复制错误。所以这里是我登录的代码：

@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
        }
    }
 }

如果我登录两次，然后再次运行该应用程序，此行将在appdelegate中崩溃。

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

如果我只登录一次，再次运行应用程序，则不会发生崩溃。崩溃的完整堆栈如下：

Answer 1

我恢复到Facebook SDK的4.17.0版本，我不再受到崩溃。

Answer 2

如果您使用的是Facebook SDK版本4.18.0，请将其更新为4.19.0或当前版本，这样您就不会崩溃。

Answer 3

确保FBSDK中没有Podfile的限制版本，如下所示：

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

然后执行pod update。不要使用--no-repo-update来更新您的本地规格库。

最新的本地规格存储库可让您下载最新版本的FBSDK，即4.19.0。
