Facebook SDK登录不适用于iOS 10，Xcode 8上的模拟器 [英] Facebook SDK Login doesn't work on simulator on iOS 10, Xcode 8

问题描述

我尝试通过viewWillAppear中的Facebook SDK登录系统登录，如下所示:

I try to login via the Facebook SDK login system in viewWillAppear like so:

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)

    if !loggedIn {
        if let token = FBSDKAccessToken.current() {
            loggedIn = true
            self.accessToken = token
        } else {
            let login = FBSDKLoginButton()
            login.center = view.center
            view.addSubview(login)
        }
    }
}

此可以在真实设备上正常运行，但是最近在iOS 10模拟器上，使用Xcode 8和Swift 3似乎失败了.登录按钮正常工作，并提示登录和授权页面，但是在授权/登录后，令牌(FBSDKAccessToken.current())仍为nil.
同样，该问题仅适用于使用iOS 10，Xcode 8和Swift 3的模拟器.

This does work properly on a real device, but lately on the iOS 10 simulator, using Xcode 8 and Swift 3 it seems to fail. The login button works normally and prompts to login and authorization page, but after authorizing/logging in, the token (FBSDKAccessToken.current()) remains nil.
Again, the problem only applies on the simulator, using iOS 10, Xcode 8 and Swift 3.

可能是问题所在，如何使它在模拟器上运行?预先感谢.

What could be the problem and how can I get this to work on the simulator? Thanks in advance.

推荐答案

如果它在真实设备上可以正常运行，则表示您已成功集成 Facebook SDK .为了使事情在iOS 10模拟器上正常运行:
转到Project Target然后转到Capabilities并切换钥匙串共享 ON .
它将首次要求一个团队.选择一个团队，它将为您添加一个钥匙串组.

If its working fine on a real device, this means that you have successfully integrated the Facebook SDK. In order to make things working on iOS 10 simulator :
Go to the Project Target and then Capabilities and switch Keychain Sharing ON.
It will ask for a Team for the first time. Select a team and it will add a Keychain Group for you.
