Question

我已经多次浏览了Facebook的“快速入门”指南，但似乎无法弄清楚导致此错误的原因。我正在尝试使用以下函数调用通过FB进行身份验证：

FBSDKLoginManager().logIn(withReadPermissions: ["public_profile", "email"], from: self) { (result, error) in

}

但是，我得到以下错误控制台输出：

-canOpenURL：URL失败：“ fbauth2：/”-错误：“操作无法完成。（OSStatus错误-10814。）”

这是我的AppDelegate方法：

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    return FBSDKApplicationDelegate.sharedInstance()!.application(application, didFinishLaunchingWithOptions: launchOptions)
}

func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
    return FBSDKApplicationDelegate.sharedInstance()!.application(app, open: url, options: options)
}

我已按照《快速入门》指南的说明，在我的Info.plist中添加了以下键/值：

<key>CFBundleURLTypes</key>
<array>
    <dict>
        <key>CFBundleURLSchemes</key>
        <array>
            <string>fb719997618357318</string>
        </array>
    </dict>
</array>
<key>FacebookAppID</key>
<string>719997618357318</string>
<key>FacebookDisplayName</key>
<string>Test</string>

<key>LSApplicationQueriesSchemes</key>
<array>
    <string>fbapi</string>
    <string>fb-messenger-share-api</string>
    <string>fbauth2</string>
    <string>fbshareextension</string>
</array>

您需要在AppDelegate中实现此方法

func application(_ application: UIApplication, open url: URL, sourceApplication: String?, annotation: Any) -> Bool{

    return FBSDKApplicationDelegate.sharedInstance().application (
        application,
        open: url as URL!,
        sourceApplication: sourceApplication,
        annotation: annotation)
}

当用户从应用程序登录时，将调用此方法。尝试一下，让我知道它是否有效，否则将尝试帮助您解决其他问题。

由于最近的Xcode 10.1更新，这是Facebook SDK中的错误。 UIApplicationDelegate的功能签名已略有更改：

// before
func application(_ app: UIApplication,
                 open url: URL,
                 options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool
// before
func application(_ app: UIApplication,
                 open url: URL,
                 options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool

关键的变化是options字典不再由String类型键入。而是将键键入为UIApplication.OpenURLOptionsKey，其定义如下：

// Inside definition of `UIApplication`
public struct OpenURLOptionsKey : Hashable, Equatable, RawRepresentable {

    public init(rawValue: String)
}

目前的解决方案是针对此线程讨论的Facebook SDK的特定版本：https://github.com/facebook/facebook-swift-sdk/issues/301。
