我目前正在使用以下代码通过自定义的精灵节点按钮登录Facebook:
func runLoginForFacebook() {
print("logging in with facebook...")
print("FACEBOOK CURRENT TOKEN ---->\(FBSDKAccessToken.current())")
let login = FBSDKLoginManager()
let viewController = UIApplication.shared.keyWindow?.rootViewController
login.logIn(withReadPermissions: ["public_profile"], from: viewController, handler: { result, error in
if error != nil {
print("Process error \(error!.localizedDescription)")
} else if result?.isCancelled != nil {
print("Cancelled \(error?.localizedDescription)")
} else {
print("Logged in")
signIntoFirebase()
}
})
}
现在,这使我可以登录并单击“继续”按钮,以便关闭屏幕,但始终将isCanceled返回为yes,而不是登录。
我已经在这个网站上搜索了所有答案,他们都说应用程序委托是问题所在,这是我的应用程序委托,这似乎很好:
class AppDelegate: UIResponder, UIApplicationDelegate, MessagingDelegate {
var window: UIWindow?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions:
return FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
}
func application(_ application: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
let handled: Bool = FBSDKApplicationDelegate.sharedInstance().application(application, open: url, sourceApplication: options[UIApplication.OpenURLOptionsKey.sourceApplication] as? String, annotation: options[UIApplication.OpenURLOptionsKey.annotation])
// Add any custom logic here.
return handled
}
下一个解决方案是我在Facebook的开发人员门户上的应用程序中没有我有任何测试用户,但我并没有使用与测试用户/管理员相同的帐户来登录该应用程序。
我还检查了我的info.plist文件,一切似乎都很好(请参阅下文。我将XXXX放在了姓名和号码中以表示原因),该数字可以很好地检查并与开发人员门户网站ID)

有人可以帮助我吗?任何想法都将不胜感激,因为我已经在这里待了一天,但我想不通。
答案 0 :(得分:1)
您正在检查if result?.isCancelled
是否为nil,因此,如果有结果,则该结果将始终为true或false,从不为null。请尝试以下代码(请注意,此代码未经测试,因此,如果我弄乱了语法,请使用正确的代码随意编辑答案)
func runLoginForFacebook() {
print("logging in with facebook...")
print("FACEBOOK CURRENT TOKEN ---->\(FBSDKAccessToken.current())")
let login = FBSDKLoginManager()
let viewController = UIApplication.shared.keyWindow?.rootViewController
login.logIn(withReadPermissions: ["public_profile"], from: viewController, handler: { result, error in
guard let result = result else {
print("No result found")
}
if result.isCancelled {
print("Cancelled \(error?.localizedDescription)")
} else if let error = error {
print("Process error \(error.localizedDescription)")
} else {
print("Logged in")
signIntoFirebase()
}
})
}
