好的，我已经实现了 Facebook 登录按钮:
loginButton.readPermissions = ["public_profile", "email", "user_friends"]
loginButton.center = (self.view?.center)!
loginButton.delegate = self
self.view?.addSubview(loginButton)
但每次我完全关闭应用程序并再次打开它时，我都需要重新加入，所以我的问题是如何让应用程序记住我已经登录过一次？
最佳答案
尝试使用这个
将此代码放入您的 appDelegate
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
if((FBSDKAccessToken.currentAccessToken()) != nil){
//user is sign in
//Put here something what you want to do if user is sign in
}
return FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
}
关于 swift 。记住 Facebook 登录信息，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/35687088/
